As a non-American citizen, you will need your passport to enter the building - a simple ID will not suffice.

It’s inside a federal building Enter from C & 3rd and bring a photo ID. You have to go through a security check to get in the lobby. Really nice staff!

I've been coming to this Post Office frequently. The staff has always been very friendly and helpful. I've been trying to leave an experience rating on the Post Office web site but they don't recognize the zip code that's associated with this Post Office.
