Calling the Port of Seattle? The Prefix for Our Phone Numbers Has Changed

All Port of Seattle phone numbers now share the same prefix – 787. So whether you’re calling the main number at Port headquarters or a Port Seaport office or Sea-Tac Airport - the first three digits of the number are now 787. The last four digits stay the same. For example, our main number was 728-3000; it is now 787-3000.

The new prefix affects Port phones only; not the phone numbers of outside businesses operating on Port of Seattle properties. Examples of outside business include airlines at Sea-Tac Airport and cruise lines and cargo carriers at Seaport terminals.

If you need to reach a specific person and don’t know their extension, just dial our main number, 787-3000, and press 5 for a directory.

The former Port phone numbers are no longer rolling over. Please note the new prefix. We don’t want to miss your call.
