How to Search for an Inmate in King County Washington

To locate an inmate within the King County Jail system, go to the King County Department of Adult & Juvenile Detention site.

Click on the Jail Lookup Service link on the left side of the page.

Then choose from:

View Jail Register – this provides information on inmates currently in custody as well as those who were booked or released within the past 24 hours.

Search Jail Booking Service – this provides information about any person who was in custody in the King County Jail system within the past 365 days.

Using the “View Jail Register” search link you will then choose one of the following:

  1. Everyone in custody, alphabetically by last name.
  2. Those booked within the last 24 hours.
  3. Those released within the last 24 hours.

Clicking on “Everyone in Custody” brings up a list alphabetized by last name of all currently incarcerated inmates and those booked or released within the past 24 hours. The top of the page also offers letter links that allow you to narrow your search to only those with last names starting with that letter.

Clicking on “Those booked with the last 24 hours” or “Those released within the last 24 hours” brings up alphabetized lists of only those people.

Clicking on the name of the inmate provides the following information:

  • Full Name
  • Housing Facility
  • Bail Amount

Under the “Booking Events” section, click on the + sign to open the information about each arrest and booking of that inmate.

The + sign will open and offer the following information:

  • Inmate visitation schedule and any restrictions
  • Court location
  • Release date/if released-the reason for release
  • Bail allowed or denied
  • Charges

Using “Search Jail Booking System”

Enter as much information as you have about the inmate such as name, birthdate, gender, race, etc.

You must enter at least two letters of the last name to search the site.  

Click “Submit”.

The system will list all inmates matching the information you presented.

*NOTE* - If entering birthdates, booking numbers (Must start with zeros and contain nine numbers), etc. they must be correct or the search will be inaccurate.


  • This system allows you to search partial last names using the “Wild Card” feature.
  • Last Name is required for a Wild Card Search. It must contain between 2 and 29 letters followed by an asterisk (optional). No special characters or numbers are allowed. If no asterisk is entered only individuals with an exact last name match will be returned.
  • Example: "wil*" will return individuals with last names starting with "wil" such as "Williams", "Wilks" and "Wiley".
  • Example: "Williams" will return individuals with last name "Williams".
  • When using a date of birth, it must be in the following format:  mm/dd/yyyy  Example 04/09/1957

If the Seattle Police Municipal Jail - King inmate search website is not currently online or up to date, call for assistance in locating your inmate.

The Seattle Police Municipal Jail - King is "open" 24-hours-a-day. When you call, give the staff member the name of who you are looking for and a birthdate or age if you have it. That person will let you know if your inmate is there.

At minimum you will need a first and last name. If you can provide the middle name or initial that is even better. In a perfect world you will also have the inmate's birthdate, but if not, an estimated age will help.

If you are not sure what county jail the inmate is located in, it helps to at least know the geographic area. Knowing what state the inmate is in is good; knowing which county is even better.

In some cases, there will be more than one possibility. Use patience and check them all. Go here to get started on a search for any jail in the state of Washington or go to this page to begin a search for all jails in the United States.

If your inmate has been charged but not yet convicted of a misdemeanor or a felony, he or she will most likely be held in King County within the county where the crime occurred.

If they are sent to the King County Jail, either look them up here or call for assistance.

Recently convicted felons are sometimes held at King County Jail until transport to a Washington State Prison is available. Inmates sentenced to less than one year incarceration or those convicted to serve time for misdemeanors will do their time in the King County Jail system.

How to find an Inmate already convicted of a felony and sentenced in the state of Washington

State Inmate

Most states have Department of Corrections websites that allow you to type in a felon's first and last name and pull up inmates in that state. Go to this page for inmates in Washington. If you need to find an inmate in another state prison system, go here.

When you click next to the inmate's name or on a link, it will show you which jail or prison the inmate is housed in. If the inmate is no longer incarcerated, but is on parole/probation or discharged, it will tell you that as well. In addition, many state prison inmate pages show recent mug shots.

Federal Inmate

The federal prison system has its own inmate locator called the Bureau of Prisons Inmate Locator.

Type in the inmate's name and it will tell you where he or she is incarcerated and their projected release date. It also lists released federal prison inmates and the date they were released.

Federal inmates who are moved from one prison to another will show as "No longer in federal custody" on the system until they reach their next federal prison destination. This movement can take a few days to several months to complete, so keep checking back to find out where the inmate was taken.

ICE Inmates

The ICE Detainee Lookup allows friends, family members and interested parties to locate illegal and/or undocumented immigrants that are in the United States without permission.

They are held in detention centers approved by Immigration Custody and Enforcement until their hearing or date they are deported back to their home country.

To look up the detainee, users need the full legal name the person used upon their arrest and the country the person claimed they originated from. It helps to also have the "A-number", which is the number that ICE assigned to them upon their detention, which you can use instead of attempting to type the detainee's name.
