Sometimes it’s nice to get a postcard with a postmark from a tropical island. HNL is a good place to drop off those postcards!
Their page on Postal Services is a pretty good reference. Where they shine is their interactive map: one loaded, click on “Services” and then “Postal Drop Boxes” for USPS drop boxes.
Definitely check the interactive map first – but if you’re on a slow connection, this is what the airport says on their Web site.
U.S. Postal Service Drop Boxes are provided as a customer service by Daniel K. Inouye International Airport. Boxes are opened daily and mail taken to the Post Office. Drop boxes are located:
- Main Terminal near Gate 13.
- Main Terminal just past Security Checkpoint #2 within the secured area.
- Inter-Island Terminal near the Security Checkpoint.
The page also mentions a business center that has full postal services:
The Business Center in the Center Lobby of the Overseas Terminal provides full mailing services. Hours: Daily 7:30 a.m.-7:30 p.m.
This business center might be post-security around Gates 14-23, but it also may be in the connector between the other two portions of the terminal.
The interactive map also has locations of other business centers – you may want to try these as well.
Walkable Post Office!
There is no official post office on airport property – but a Google search provided the nearest post office on Aolele St. This is definitely walkable from the airport terminal if you have lots of time before your flight – or if you’re rushed and need to drop off something before returning a rental car.
From the airport terminals: head to the inter-island terminal. Get to the ground floor. Exit the building, turn left, and walk out from underneath the airport structure. Cross the street (be mindful of traffic!). You should see a building in front of you – that’s the post office facility. When in doubt, open the link above. I expect that it will take 10-15 minutes to travel there in each direction (probably 20-25 from the far terminals like Gate 9), so I wouldn’t head there on foot if you don’t have 2-3 hours before your flight out.
This post office is full service, open until 8pm on weekdays (4pm on Saturday), has a lobby open 24/7 with PO Box access, and has automated postal machines should you need to mail parcels. Note that anything that doesn’t meet First Class Parcel requirements (such as Priority Mail) may need to be mailed when the counter is open.
Fair warning: reviews posted on Google indicate that this is not a highly rated post office for customer service.
