Person Lookup in King County gives you direct access to public person records that reveal name variations, current and previous addresses, phone details, and linked property or court documents. By entering a full name, first and last name, or even a partial name, you can narrow results with location filters such as city, ZIP code, county, or state. The search portal also supports person lookup by address, phone number, or a combination of details, helping you distinguish people with common names and avoid incorrect matches. Users often ask how to find someone by phone number or how to identify the correct person from public records; the system returns data that includes residential and mailing locations, phone history, and associated businesses, all drawn from up‑to‑date public record sources. This approach meets the need for reliable individual records search while respecting privacy limits on restricted information.
Person Lookup also serves researchers looking for genealogical clues, property owners, or legal histories. When you perform a person lookup by address or by location, the results show address history, ZIP code changes, and county records that can confirm identity matches. Common questions like how to find a person by city and state or how to locate someone’s previous address are answered through integrated public records search, which aggregates property, marriage, and court data. By focusing on accurate, verifiable information, the service reduces the frustration of too many matching people and helps you quickly pinpoint the individual you need.
How to Search for a Person
Person Lookup in King County gives you a direct way to find records about residents using official public data. You can begin with a name, a phone number, or an address, and then narrow the results by adding a city, ZIP code, including address lookup, or county filter. The portal pulls data from property files, court filings, and other government sources to help you confirm identity. Once you enter your search criteria, the system displays a list of possible matches for you to review.

Steps to Search
- Open the King County Assessor eRealProperty portal using the URL listed above.
- Type the full name, last name, or business name into the owner search field.
- Add a location filter such as city, ZIP code, or street name to narrow the list.
- Press the search button and wait for the results page to load with all matching entries.
- Review each result and click the parcel number to see full property and owner details.
- Compare addresses, names, and parcel data across results to identify the correct person.
Search by Full Name
Entering a full name, such as a first and last name together, often returns the most accurate results. The search engine looks for exact matches first and then shows close variations. This method works well when you know the spelling and want to skip unrelated records. A full name search cuts down the number of possible identity matches you must review.
Search by First and Last Name
If you only know part of a name, you can search using a first name and last name in separate fields. The portal will return any record that contains both entries, even if a middle name or initial appears in the file. This approach helps when you are unsure about spelling or want to check relatives who share a surname. Results will show all linked parcels and property records for that name combo.
Search by Location
Location-based searches start with a city, ZIP code, or street address rather than a name. This method helps you find residents in a specific neighborhood or district. When you enter a location, the system lists all owners tied to parcels in that area. You can then scan the list to find the person you are looking for.
Search by City and ZIP Code
Combining a city with a ZIP code tightens your search range. Many cities in King County share ZIP codes, so adding both fields removes overlap from nearby towns. The portal will then show only records tied to that exact area. This is helpful when you want to find a person living in a specific part of Seattle, Bellevue, or another city.
Search by Phone Number
Some public records link a phone number to a name or address. You can type a phone number into the search field and see if any parcel or record ties back to that line. The result will show the owner name and the property address on file. Phone searches work best with landline numbers, which are more often listed in public filings.
Search by Address
Searching by address shows the current owner of a property at that location. Enter the street number and name, and the portal returns the parcel owner on record. This method helps when you want to know who lives at a certain home or business site. It also shows past owners if address history is available.
Search Using Multiple Details
Adding more than one piece of data to your search, such as a name plus a city, often gives you sharper results. The system will filter for records that match all the details you entered. This cuts down on common name problems and reduces duplicate entries. The more you know about the person, the faster you can confirm a match.
Information Needed for a Person Lookup
Before you start, gather any data you already have about the person. Useful details include a full name, a known address, a phone number, or a city and ZIP code. Even partial information can guide the search in the right direction. The table below shows common search inputs and what they help you find.
| Search Input | Best Use | Result Type |
|---|---|---|
| Full name | Confirming identity | Owner and parcel records |
| Phone number | Tracing a line | Name and address link |
| Street address | Finding a resident | Property owner |
| City and ZIP code | Narrowing by area | List of nearby owners |
Person Lookup Results
Once your search runs, the portal returns a list of possible matches tied to public records. Each entry shows a name, an address, and a parcel or record number. You can click on any entry to see more details. The results page is the main hub for confirming identity and gathering contact data.
Full Name
The first result field shows the full name on file, which may include middle names or initials. Public records often list the legal name used at the time of filing. This field helps you confirm whether the person you searched for is the same as the one on record. Spelling differences may point to name variations rather than a different person.
Possible Name Variations
The system may display alternate spellings or shortened versions of a name. Common variations include nicknames, hyphenated last names, and married or maiden names. Reviewing these entries helps you spot a person whose name has changed over time. Each variation links back to the same record set for easy cross-checking.
General Location
Each record shows a general location, such as a city or ZIP code, tied to the person. This field narrows the result to a specific area within King County. Comparing locations across results can help you rule out people who live too far away. General location data supports faster identity matching.
Current or Previous Addresses
The portal lists both current and past addresses linked to a person when available. You may see a home address, a mailing address, or a business location. Older entries help you track address changes over time. This data is useful when you need to confirm a long-term resident or trace a move.
Phone Numbers
Some records display a publicly listed phone number next to the name and address. These numbers often come from landline filings or business registrations. Mobile numbers are less common in public files but may appear in court or business records. Phone numbers help you verify that you have found the right individual.
Associated Businesses
Results may list businesses owned or linked to the person on file. These entries often include a business name, a registration number, and a business address. Business ties help you confirm identity for self-employed individuals or company owners. They also help researchers trace commercial activity tied to a name.
Public Record References
Each result includes a record reference number or parcel ID tied to the entry. This number lets you open the full file for more detail. Public record references also link you to court, marriage, or property filings. The reference number is the best way to follow a person across multiple data sets.
Identifying the Correct Person
Public records often list several people with the same name, so you need a clear method for picking the right one. Start by matching the strongest data points, such as age, location, or known addresses. The portal gives you enough detail to compare entries side by side. A careful review saves time and prevents errors.
Matching Names
Begin by checking the full name and spelling on each result. Look for middle names, initials, or suffixes that match what you know. Even small spelling differences can point to a different person. Name matching is the first filter you should apply when reviewing a list of results.
Comparing Locations
Locations help you rule out people who live in the wrong city or ZIP code. A person living in Seattle is likely not the same as one living in Renton if you know the correct area. Use location data to narrow your list to records that match your target’s known area. This step is key when dealing with common names.
Comparing Ages or Birth Information
Birth years or age ranges help you confirm identity when names overlap. Some records show an approximate birth year or age tied to a property filing. If you know the age of the person you seek, use this data to rule out older or younger entries. Age checks are helpful for genealogical research.
Matching Addresses
Address matching is one of the strongest tools for confirming a person. If you know a past address, you can search for that address first and see who lived there. The portal will show current and past owners for each parcel. This approach works well for tracing a single individual over time.
Comparing Phone Numbers
Phone numbers on file can verify whether two records belong to the same person. If a number from your search matches a known contact, the match is likely correct. The portal shows numbers in a list tied to each record. Cross-checking numbers across entries helps you confirm a match.
Distinguishing Between Similar Records
When many results look alike, use every field together rather than one alone. Combine name, age, location, and phone data to form a full picture. The table below shows how to weigh each field when results look close.
| Field to Check | Why It Matters | Weight in Matching |
|---|---|---|
| Full name | Core identifier | High |
| City or ZIP code | Filters out wrong area | High |
| Age or birth year | Removes wrong age groups | Medium |
| Phone number | Confirms contact line | Medium |
| Associated business | Adds work link | Low |
Person Information
Each record on the King County portal shows several layers of personal data drawn from public files. The system compiles name, address, phone, and business data into a single profile. You can use this profile to confirm identity or build a contact list. All data comes from open public record sources, so accuracy depends on how often each source is updated.
Name and Identity Details
The name and identity section shows the legal name tied to a parcel or court record. It may also list a date of birth, a middle name, or an alternate spelling. These details help you tell two people apart when other fields overlap. Identity details form the base layer of every search.
Address Information
The address field shows a street address, a city, a ZIP code, and sometimes a county. You may see more than one address if the person has moved or owns several properties. Address data ties a person to a physical location. It is also the fastest way to confirm you have the right record.
Phone Information
Phone information includes any publicly listed number tied to the name or address. These numbers may come from landline filings, business registrations, or court documents. Phone data is useful when you want to call or text the person. It also helps confirm identity when paired with an address.
Location History
Location history tracks where a person has lived or owned property over time. You can see moves between cities, ZIP code changes, and past counties. This data helps with genealogy, legal research, and reconnecting with old contacts. A history trail often tells a clearer story than a single address.
Associated Names
Associated names include relatives, business partners, or co-owners on a property. The system may show spouses, children, or joint owners on a deed. These names help you expand a search or verify family ties. They are useful when you need to find a related person on file.
Associated Businesses
Business ties include any company where the person is listed as an owner, officer, or registered agent. Each business shows a name, a registration number, and a business address. This data supports research on self-employed individuals and company officers. It also helps confirm professional identity.
Publicly Available Records
The portal links to all publicly available records tied to the person, including property, court, and marriage filings. These records form the full picture of the individual. Each record type carries its own update cycle and source agency. Together, they form the public profile you can search.
Address History
Address history is one of the strongest features of the King County portal. You can see where a person lived at each stage of their life, based on property filings and public records. This trail helps you confirm identity, trace moves, and build a timeline. Older entries often come from historical deeds or property transfers.
Current Address Information
The current address is the most recent location tied to the person on file. It appears in property tax records, voter rolls, or court filings. This field is the starting point for most contact efforts. If the entry is recent, it likely shows where the person lives now.
Previous Address Information
Previous addresses show every known location from past filings. Each older address has a date range or filing year, when available. This data helps you trace the person across King County or out of state. It is also useful for genealogy and family research.
Address Changes
Address changes show the pattern of moves between homes, cities, or states. You can see the gap between filings, along with residents directory and how often a person relocated. This data is useful for skip tracing, legal notices, and personal reconnect efforts. The system logs each change as a separate record when it can.
Historical Locations
Historical locations cover older filings, some going back decades. These entries often come from scanned deeds, hand-indexed ledgers, or archive boxes. You may need to request older files in person at the Assessor’s Office. Historical data is key for long-term research.
Mailing and Residential Addresses
The portal sometimes lists a mailing address that differs from the residential address. Property owners may use a P.O. Box or a separate office for mail. The residential address is the actual home location. Comparing the two helps you avoid sending mail to the wrong place.
- Mailing address: used for tax bills and official notices
- Residential address: the physical home or property site
- Business address: the work or office location, when listed
- Historical address: a past home or property no longer on file
Phone Information
Phone information in public records comes from filings where a number was tied to a name or address. Landlines appear more often than mobile numbers because they are listed with utility and public filings. You can use phone data to confirm identity or to reach a person directly. Each number links back to a record source.
Associated Phone Numbers
Associated phone numbers show every line on file for the person. You may see a home number, a work number, or a fax line. The portal lists each number with its source, when available. This helps you pick the right line for your needs.
Mobile Numbers
Mobile numbers appear less often in public records but may show up in court filings or business registrations. When listed, they give you a direct contact line. Keep in mind that mobile data may be older or outdated. Always verify before using it.
Landline Numbers
Landline numbers are the most common type on file. They show up in property tax filings, utility listings, and voter rolls. Landlines are tied to a fixed address, which makes them useful for identity checks. These numbers tend to be more stable over time.
Business Numbers
Business numbers appear in corporate filings, trade name registrations, and license records. They are tied to a company rather than a private home. If the person owns a business, the work number is often the easiest line to reach. The portal lists business numbers next to the company name.
Phone Number History
Phone history shows older numbers that may no longer be active. Past numbers help you trace contact history and confirm identity over time. They also help with legal research where past contact data matters. You can request older phone records from public archives when needed.
Publicly Listed Numbers
Publicly listed numbers come from open sources, such as phone directories, public filings, and government databases. These numbers are open for anyone to view under public record laws. Numbers not in public files do not appear in search results. Always check the source before relying on a number for legal use.
Person Lookup by Location
Location-based searches help you find people in a specific city, ZIP code, county, or state. This method is useful when you only know where the person lives but not the exact name. The portal returns all owners and records in the chosen area. You can then scan the list to find the right individual.
Search by City
A city search shows every person on file within that city limit. You may see hundreds of results in larger cities like Seattle. Adding more details, such as a street or ZIP code, cuts the list down. City searches work well for narrow neighborhoods or small towns.
Search by ZIP Code
ZIP code searches pull records from a defined postal area. This method helps you focus on a small section of a city or a rural area. ZIP codes often cross city lines, so be ready for results from nearby towns. Use this search when you know the postal code but not the full address.
Search by County
County searches return all records filed within King County. This is the broadest location filter, so expect a large list. You can use it for general research, but pair it with a name to get sharper results. The county search draws from the Assessor’s office and other public agencies.
Search by State
State searches show records filed across Washington State. This option is useful when a person has moved out of King County but still has files on record. The portal links out to state-level sources for older or out-of-county records. You may need to check other state portals for full data.
Location-Based Results
Location results group people by area, showing names and addresses tied to each parcel. The system sorts results by parcel number, street, or ZIP code, depending on your filter. This layout helps you scan a list quickly. Each entry links to a full record for deeper review.
Narrowing Results by Location
You can narrow results by adding more location details to your search. Try a street name, a neighborhood, or a specific ZIP code. The more precise your filter, the smaller and more accurate the list. Narrowing is the fastest way to find one person among many common names.
Public Records Connected to a Person
Public records include property files, court cases, business filings, marriage and divorce records, and genealogy data. These records form the full public profile of a person. The King County portal links many of these sources in one place. You can use them to confirm identity or research a person’s history.
Property Records
Property records show who owns a parcel, how much it is worth, and what taxes are due. They include deeds, mortgages, and transfer filings. These records are useful for finding current and past owners. They form the core of most person lookup results.
Business Records
Business records list every registered company tied to a person. They include trade names, LLC filings, and corporate officer roles. You can see when a business started and where it operates. These records help confirm self-employment or company ownership.
Court Records
Court records show civil, criminal, and small claims filings tied to a person. Each case shows a case number, a filing date, and the court where it was heard. Court records are open to the public unless sealed by a judge. They are useful for legal research and background checks.
Marriage and Divorce Records
Marriage and divorce records show legal unions and dissolutions. They include names of both parties, dates, and the court that handled the filing. These records help with genealogy and family research. They also confirm a spouse or former partner tied to a person.
Publicly Available Government Records
Government records include filings from city, county, and state agencies. They cover licenses, permits, voter rolls, and public contracts. Each agency has its own rules for public access. The King County portal links to many of these files.
Genealogical Records
Genealogical records help you trace family history and family ties. They include birth indexes, census data, and historical deeds. The portal may link to archives for older entries. These records are useful for family researchers and historians.
- Property files from the Assessor’s Office
- Court filings from King County Superior Court
- Marriage and divorce filings from the county clerk
- Business filings from the Washington Secretary of State
- Genealogy archives linked through public libraries
Person Lookup Accuracy
Public records are reliable, but they are only as current as the last filing. Some data may be outdated or incomplete. Understanding how records are updated helps you set the right expectations. Always cross-check key details before relying on a match.
Matching Records to the Correct Individual
Matching records takes care when names are common. Start with the strongest data points, like full name, age, and address. The portal gives you several fields to compare. A careful review lowers the risk of picking the wrong person.
Names and Duplicate Results
Common names, such as Smith or Johnson, often return many results. Each entry may look alike at first glance. Use additional filters like city, age, or business ties to narrow the list. Duplicate entries are common and not a sign of error.
Outdated Information
Public records can lag behind real life. A person may have moved, changed a phone number, or changed a name since the last filing. Always treat older data as a starting point, not a final answer. Recent filings carry more weight.
Incomplete Records
Some records are missing data because the original filing did not include every detail. For example, a deed may not list a phone number. Incomplete records are normal in public systems. You may need to check several sources to fill the gaps.
Conflicting Information
Different agencies may list different data for the same person. One filing may show a current address, while another shows a past one. Conflicting data is not always an error. It may reflect different points in time.
Record Update Frequency
Record update frequency depends on the source. Property files update with each transfer. Court files update with each filing. Business files update with each annual report. Voter rolls update each election cycle. Knowing the update cycle helps you judge how current the data is.
Limitations of Person Lookup Results
Person lookup results have limits based on what is on file. Restricted personal data, unlisted numbers, and sealed court cases do not appear. The portal only shows publicly available data. Use the results as a guide, not a complete record.
Person Lookup Privacy and Public Information
Public records respect privacy laws while still giving you access to open data. The portal only shows what the law allows. Restricted and private information is kept off the search results. You should also use the data responsibly.
Publicly Available Information
Publicly available information includes names, addresses, property ownership, court filings, and business roles. These records are open by law. You can view them without asking for permission. They form the base of any person lookup.
Restricted Personal Information
Restricted personal information includes Social Security numbers, financial account details, and medical data. These fields are not in public files. The portal removes them to protect privacy. You cannot find them through a standard person search.
Unlisted Information
Unlisted information covers phone numbers, addresses, and other details that a person chose to keep private. These data points may not appear in public searches. Some unlisted data shows up in court or property filings. Most does not.
Privacy Considerations
Privacy considerations matter when using public record data. Always handle results with care and respect the law. Do not use the data for harassment, fraud, or unlawful purposes. The portal gives you access, but the responsibility sits with you.
Responsible Use of Public Records
Responsible use means using public records for legal and fair purposes. Common uses include reconnecting with relatives, verifying identity, conducting research, and supporting legal work. The data is a tool, not a weapon. Always act within the law.
Information That May Not Be Available
Some information may not be available through public sources. Sealed court cases, juvenile records, and protected identity filings stay private. Unlisted phone numbers and confidential addresses also stay off the search. The table below shows what you can and cannot find.
| Data Type | Publicly Available | Restricted |
|---|---|---|
| Full name | Yes | No |
| Phone number | Sometimes | Often unlisted |
| Email address | Rarely | Yes |
| Court filings | Yes, unless sealed | Sealed cases only |
| Financial records | No | Always private |
Person Lookup Problems
Person lookup can hit roadblocks when data is missing, outdated, or repeated across many entries. Knowing the common issues helps you solve them. Each problem has a clear cause and a practical fix. The portal gives you tools to work around most issues.
Person Not Found
A person not found result means the portal has no matching record. The person may live in another county, have a different name, or never have filed public paperwork. Try a broader search with fewer filters. You can also check nearby counties or state files.
Too Many Matching Results
Too many matching results often happens with common names. The portal returns every record that shares the name. Add filters like city, ZIP code, or age to narrow the list. A multi-field search cuts down the noise fast.
Incorrect Match
An incorrect match happens when you pick the wrong entry from a list. The system cannot know which person you want without filters. Always cross-check age, address, and known history before confirming a match. A second search helps verify the pick.
Similar Names
Common or similar names return duplicate entries. Spelling variations also add to the count. Search using full name plus a location to separate the entries. Middle names and initials often clear up the confusion.
Outdated Address Information
Outdated address information comes from older filings. A person may have moved since the last record. Use address history to find past and current locations. The most recent filing is usually the most accurate.
Missing Phone Information
Missing phone information is common for mobile-only users. Public files lean toward landlines. Court filings and business registrations may carry a number. If no number shows up, the person likely has an unlisted line.
Limited Public Records
Limited public records happen when a person has few filings. Young adults, renters, and people new to the area often have thinner files. You may need to check other counties or state systems for more data.

Frequently Asked Questions
Find quick answers about using the King County Person Lookup tool for name, address, phone and other public record searches.
How can I do a person lookup by name?
Start at the King County Assessor’s online portal. Enter the full or partial name in the search box and click Search. The system matches the input against public records such as property ownership, court filings and voter registrations. Results show a list of possible matches with basic details like address and parcel number. You can refine the list by adding a city, ZIP code or county filter to narrow down the correct individual. Each record links to more detailed property and court information.
What info appears in a King County person search?
The search returns publicly available data tied to the person. Typical fields include current residential address, mailing address, property parcel ID, ownership history, and any associated court cases. Phone numbers appear only if they are part of a public record, such as a business listing. The portal may also show tax assessment values and land use codes. All data comes from government sources and is updated whenever the underlying records are refreshed by the county.
How do I find a person using an address?
Enter the known address in the search portal’s address field. The system looks up the parcel record linked to that location and displays the owner’s name and contact details. If the address has multiple units, each unit appears as a separate entry. You can then click the owner’s name to view additional records like tax assessments or prior ownership. Adding a city or ZIP code helps eliminate nearby addresses that share similar street names.
Can I search for someone by phone number?
Phone numbers are searchable only when they appear in a public record, such as a business license or court filing. Input the full number, including area code, into the phone search field. If the number is indexed, the portal returns the associated name and address. Many residential numbers are not listed, so results may be limited. For best results, verify the number’s format and try variations without dashes or spaces.
Why might a person not appear in the search?
A missing record often means the individual has no publicly filed documents in King County. Common reasons include recent moves, name changes not yet recorded, or ownership of property outside the county. Privacy restrictions can also hide certain details, especially for minors or protected individuals. If you expect a record, double‑check spelling, try alternate name forms, and ensure you are searching within the correct jurisdiction.
