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 Kansas record so you can verify at the source.
The whole country in one search
People move. One search here covers Kansas and every other US registry at once, so a registration in Colorado and Missouri shows up on someone now living in Wichita.
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 Kansas state site vs searching here
Kansas's own public search is Kansas Offender Registry (KBI) — free, official, and the right place for a one-off look at a single state. Here is what changes when you run the same search here instead.
| On the Kansas state site | Searching here | |
|---|---|---|
| Coverage per search | Kansas 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 Kansas dataset, specifically
| Scope | Kansas is in every nationwide search by default, and one setting narrows to it alone — in the dashboard a dropdown, in the API jurisdictions: ["KS"]. |
|---|---|
| Date-of-birth matching | A date-of-birth criterion in Kansas resolves at full-date precision on part of the roster and at year precision on the rest, and the label on each record says which. Match strength is a label on every record — dob_match / year_match — rather than a boolean, so you set your own threshold instead of inheriting ours. 1 of the 56 jurisdictions we cover resolve it the way Kansas does. |
| Best criteria to send | Send dob whenever you hold one — it is accepted in Kansas 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. Kansas returns both full-date and lower-precision matches in the same result set, and matchState distinguishes them per record. |
| Location search | Narrow to a Kansas 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 Wichita 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 Kansas match links to the person's official entry on Kansas Offender Registry (KBI), 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 Kansas behaves next to the jurisdictions around it
Registration follows the person, not the state line, so screening that covers Kansas almost always has to read Colorado, Missouri, Nebraska and Oklahoma in the same breath. One search here covers every row below at once.
| Jurisdiction | Date-of-birth match | matchState returned | Registered population |
|---|---|---|---|
| Kansas | Date or year | dob_match / year_match | — |
| Colorado | Full date | dob_match | ≈ 10,400 |
| Missouri | Full date | dob_match | — |
| Nebraska | Full date | dob_match | — |
| Oklahoma | Full date | dob_match | ≈ 8,330 |
The step-by-step procedure is on the Kansas search guide.
Building Kansas screening into your product?
The same dataset behind the search above is a full REST API: one request covers Kansas 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 Kansas 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. Kansas returns both full-date and lower-precision matches in the same result set, and matchState distinguishes them per record.

What comes back for KS
| 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 Kansas integration is the nationwide integration. Field-by-field definitions are in the Record object.
Kansas offender search FAQ
How many registered sex offenders are there in Kansas?
Kansas 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 Kansas's official registry site or here?
Kansas Offender Registry (KBI) is free and covers Kansas. Searching here covers Kansas 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 Kansas 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: ["KS"] to scope the answer to Kansas. Send dob whenever you hold one — it is accepted in Kansas 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. Kansas returns both full-date and lower-precision matches in the same result set, and matchState distinguishes them per record.
Does a Kansas 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 Colorado and Missouri surfaces on someone now living in Kansas. Scoping to Kansas narrows deliberately to the KS roster — the two are one setting apart, and every response reports which registries answered.
What does a Kansas record contain?
Every KS 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 Kansas by city or ZIP code?
Yes. Narrow to any Kansas 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 Wichita reads differently from a home address, and each entry carries its own city, county, ZIP and coordinates where geocoded.
How current is a Kansas 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 Kansas
We'll email you when a registered offender is added or moves near your Kansas 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.
