I had to dig for the information but it looks like there’s at least a mail drop and a good place to buy stamps.

User-Submitted Information

Robert sent a postcard late in 2022 with the following information:

North Terminal: Silver mailbox first floor in wall by “AK Tourist Info”.
South Terminal: blue mailbxo upper level cubside by door 2 (Alaskan)

Pickup times are Monday-Friday 5:45pm, Saturday 3:45pm.

Official Information

Drop boxes

For the South Terminal, there’s a pre-security mail drop on the departures level by the Starbucks and the Alaska Airlines e-ticket check-in terminals. Note that the mail drop might be outside; take the necessary precautions if it’s cold outside.

The FAQ also states that there’s a drop box for the North Terminal “just inside the North entry doors”. No map is provided; the link is broken.

Purchasing Stamps

The FAQ indicates that Alaska Luggage and Seafood Shipping, in the South Terminal level 2 (departures) across from the United/Delta check-in counters, has stamps for purchase. This is on the other side of the elevators relative to the South Terminal mail drop.
