For Adults
What do I need to bring?
- A photo ID with your birthdate (current or expired).
- Examples: Driver’s License, Passport, Washington ID Card, U.S. Military ID, Matricula Consular.
-
Proof of your current residential address (must be current).
- Examples: Washington Driver’s License or ID Card, utility bill (printout OK), printed checks, apartment lease, voter registration, King County tax bill, or another official/legal document.
Tip: If your photo ID already shows your current address, it counts for both ID and address verification. If it doesn’t, just bring an additional document with your current address.
For Minors
Do kids need photo ID?
- No, minors do not need photo ID.
How do kids show proof of address?
- A parent or guardian can provide proof of address (see examples above).
- Or, if a child applies without a parent/guardian, the library can mail them a “Dear Parent” postcard. Bringing back this postcard counts as address verification.
