THE ARCH Building at Seattle Convention Center 

The Seattle Convention Center (SCC), formerly the Washington State Convention Center (WSCC), is a convention center in Seattle, Washington, United States with exhibition halls and meeting rooms. The entire facility was renamed to the Seattle Convention Center in 2022, with the first two buildings named "The Arch", located along Pike Street and the recent expansion named "The Summit" on the north side of Pine Street.

The selected venue for World Congress 2024 is the Arch building.

We are making every effort to add more government rooms, in the meantime we recommend making a reservation for the available nights and sending an email to to be waitlisted for any extra nights.
