How to locate a person in jail
Learn how to find out if an adult is in custody at a King County jail.
Subject Lookup tool for adults in King County jails
Use the King County Subject Lookup Tool to:
- Find out if an adult is currently in custody in King County,
- Learn where an individual is being held, or
- Find an individual's booking number. This is sometimes called a Book of Arrest (B/A) number.
You may need a B/A to contact a person in custody or to send them money.
Another way to search for adults in custody is by using the jails' phone system: 206-296-1234.
If you believe a youth (under age 18) is in custody, call 206-263-9595 (24 hours a day, 7 days a week).
