Photographs and official records
Matches come back as people, not rows — the registry photograph, date of birth, addresses and offense, with a link to the official Washington record so you can verify at the source.
The whole country in one search
People move. One search here covers Washington and every other US registry at once, so a registration in Idaho and Oregon shows up on someone now living in Seattle.
Every search, kept
Each check is stored with the results you saw — an audit trail you can reopen, share with teammates, and stand behind later. Upload a CSV to screen a whole list in one pass.
Searching the Washington state site vs searching here
Washington's own public search is Washington State Sex Offender Registry (WASPC) — free, official, and the right place for a one-off look at a single state. The official search is operated by a third-party notification vendor and runs one law-enforcement agency at a time rather than statewide in one query. Here is what changes when you run the same search here instead.
| On the Washington state site | Searching here | |
|---|---|---|
| Coverage per search | Washington only. A registration in any other state never appears. | Every US registry at once — the 50 states, DC and the territories. 58 registries in one search. |
| Your search history | Nothing is saved. Checking the same person next month means starting over, with no record you ever looked. | Every search is stored with the results you saw — a real audit trail you can reopen. |
| Narrowing a common name | Whatever the search form offers, one attempt at a time. | Date of birth, age give-or-take, city, ZIP, street address — and misspellings caught when you want them. |
| Checking a whole list | One name at a time, by hand. | Upload a CSV and screen everyone in one pass. |
| Working as a team | No accounts, so no way to share what has been checked. | Add teammates to one workspace with a shared history. |
| Building it into your product | No API. | A full REST API on the same data, when you are ready for it. |
Start with 25 free searches — create an account and run the first one in under a minute.
The Washington dataset, specifically
| Scope | Washington is in every nationwide search by default, and one setting narrows to it alone — in the dashboard a dropdown, in the API jurisdictions: ["WA"]. |
|---|---|
| Date-of-birth matching | A date-of-birth criterion in Washington resolves against age within the tolerance set by ageTolerance and returns age_match. Match strength is a label on every record — age_match — rather than a boolean, so you set your own threshold instead of inheriting ours. 7 of the 56 jurisdictions we cover resolve it the way Washington does. |
| Best criteria to send | Send dob whenever you hold one — it is accepted in Washington exactly as it is everywhere else, and it narrows rather than filters, so a record with thinner birth evidence still comes back on the name. In Washington it resolves against age, returning age_match; send age instead when a date is not something you hold, and widen or tighten with ageTolerance. |
| Location search | Narrow to a Washington city or ZIP, or search a radius of up to 100 miles around a point. Addresses come back as typed entries — residence, secondary, employment, school — so a work address in Seattle is distinguishable from a home address. |
| Freshness | Continuously updated, so a Regular result is close to live. Send a live block to re-verify named jurisdictions at the source in the request, and every record returns its own lastCheckedAt. |
| Verification | Every Washington match links to the person's official entry on Washington State Sex Offender Registry (WASPC), so any record can be confirmed at the official registry before you act on it. Registry data is not a consumer report, and decisions made on it are regulated in that use. |
How Washington behaves next to the jurisdictions around it
Registration follows the person, not the state line, so screening that covers Washington almost always has to read Idaho, Oregon and Alaska in the same breath. One search here covers every row below at once.
| Jurisdiction | Date-of-birth match | matchState returned | Registered population |
|---|---|---|---|
| Washington | Age precision | age_match | — |
| Idaho | Full date | dob_match | — |
| Oregon | Full date | dob_match | ≈ 34,600 |
| Alaska | Full date | dob_match | ≈ 3,730 |
The step-by-step procedure is on the Washington search guide.
Building Washington screening into your product?
The same dataset behind the search above is a full REST API: one request covers Washington or all 58 jurisdictions, every match scored and labelled, per-source status on every response. A last name is the only required criterion. Send dob whenever you hold one — it is accepted in Washington exactly as it is everywhere else, and it narrows rather than filters, so a record with thinner birth evidence still comes back on the name. In Washington it resolves against age, returning age_match; send age instead when a date is not something you hold, and widen or tighten with ageTolerance.

What comes back for WA
| Identity | legal name and name parts, every recorded alias, sex, race and ethnicity, and the matched name that actually answered your query |
|---|---|
| Birth evidence | dob, birthYear and age, each populated to the precision available, with dobPrecision naming that precision explicitly |
| Physical description | height, weight, eye and hair colour, and scars, marks and tattoos |
| Addresses | residence, plus secondary, employment and school addresses as separate typed entries, each with line1, city, county, state, ZIP and coordinates where geocoded |
| Offense | offense description, statute, conviction and offense dates, conviction county and state, case number, conviction count, and victim age and sex |
| Registration | tier or risk level, registration start and end dates, last verification, compliance and custody status, absconder and predator flags, and the registering agency |
| Media | images[], newest first, with images[0] as the current photograph |
| Match & provenance | matchConfidence, matchBasis[], matchState, and lastCheckedAt on every record |
The same shape in all 58 jurisdictions — the reason the Washington integration is the nationwide integration. Field-by-field definitions are in the Record object.
Washington offender search FAQ
How many registered sex offenders are there in Washington?
Washington is a jurisdiction where the size of the register moves week to week, and a single headline number would be out of date the day it was published. A search answers the question that actually matters — whether a named person appears — with a scored, labelled result rather than a count.
Should I search Washington's official registry site or here?
Washington State Sex Offender Registry (WASPC) is free and covers Washington. Searching here covers Washington and every other US registry in the same search, keeps a stored history of every check you run with the results you saw, narrows by date of birth, age, city, ZIP or street address, takes a whole CSV list at once, supports teammates on one workspace, and has a full API behind it. If you check people more than once, or people who may have lived anywhere else, that is the difference that matters.
How do I search Washington sex offender records by name and date of birth?
Type a last name and add whatever else you hold — first name, date of birth, city or ZIP. In the dashboard that is a form; through the API it is one request with jurisdictions: ["WA"] to scope the answer to Washington. Send dob whenever you hold one — it is accepted in Washington exactly as it is everywhere else, and it narrows rather than filters, so a record with thinner birth evidence still comes back on the name. In Washington it resolves against age, returning age_match; send age instead when a date is not something you hold, and widen or tighten with ageTolerance.
Does a Washington search include people registered in other states?
It does when you let it. A search with no state scope runs across every US registry in one pass, which is how a prior registration in Idaho and Oregon surfaces on someone now living in Washington. Scoping to Washington narrows deliberately to the WA roster — the two are one setting apart, and every response reports which registries answered.
What does a Washington record contain?
Every WA record returns under the same normalized shape as the other 57 jurisdictions: identity and aliases, birth evidence with its precision stated, physical description, typed addresses, offense and conviction detail, tier or risk level, registration and compliance status, photographs newest-first, and match scoring on every record. One integration — or one dashboard — reads all of them.
Can I search Washington by city or ZIP code?
Yes. Narrow to any Washington city or ZIP, or sweep a radius of up to 100 miles around a point. Addresses come back as typed entries — residence, secondary, employment, school — so a work address in Seattle reads differently from a home address, and each entry carries its own city, county, ZIP and coordinates where geocoded.
How current is a Washington result?
The dataset is continuously updated, so a Regular result is close to live — and when a decision needs a current, moment-of-decision check, a live block re-verifies the named jurisdictions at the source in the same request. Every record returns its own lastCheckedAt, so currency is a value you read off the response rather than a claim you take on trust.
Get alerts for Washington
We'll email you when a registered offender is added or moves near your Washington address. A monitor is a recurring watch on our continuously updated data, checked every morning — set one on an address and radius, or on one person by name and date of birth.
Area monitoring is $10/mo; watching one person by name is $3/mo. Send the alerts to yourself and anyone else who should know, and turn a monitor off any time.
This is not a consumer report and must not be used for FCRA-governed hiring, tenancy, or credit decisions.
