King County District Court Passport Office

The King County District Court Passport Office, housed inside the King County Courthouse at 516 Third Avenue in downtown Seattle, offers a distinctive court-administered passport acceptance service in the city's civic core. Suite E327 on the third floor processes first-time applications and qualifying renewals, drawing applicants who work in or near the government and legal district of downtown Seattle.

The court operates on a walk-in basis during business hours — Monday through Friday, 8:30 a.m. to 3:30 p.m. — making it one of the few Seattle-area acceptance facilities that does not require a pre-booked appointment slot. This can be a meaningful advantage for applicants with unpredictable schedules. One important payment note: the courthouse does not accept credit cards; fees must be paid by check or money order.

Given its location at the heart of downtown, the courthouse is steps from the Pioneer Square Link station and served by multiple Metro bus routes on Third Avenue. Applicants who need an urgent passport and qualify for walk-in service at the nearby Seattle Passport Agency (300 Fifth Ave, a two-block walk) will also find this location a natural first stop for their standard DS-11 paperwork.

This is one of the only passport acceptance facilities in Seattle that accepts walk-ins without a pre-scheduled appointment — a significant perk in a city where USPS slots often fill weeks in advance. Payment is by check or money order only; credit cards are not accepted. The courthouse location is also notable for its proximity to the Seattle Passport Agency at 300 Fifth Avenue — if you have imminent international travel (within 14 days) and need an emergency passport, the Agency is a two-minute walk.
