Located on the first floor of Tripler Army Medical Center on Oceanside. The post office is located next to the mail room and near the credit union(can’t remember the name) and across from the barbershop, florist, and optical shop. A very small post office which serves your basic postal needs. You can purchase stamps, mail out Media Mail, First Class Mail, Priority Mail, Express Mail, and International Mail items. They have a small supply of «flat rate» Priority boxes inside the post office as well as «decorated» packaging that you can purchase. The post office itself can only fit about 7 people in line(comfortably) and it can get tight as people are filling out addresses or forms on the counter. During Christmas I’ve seen the line out the door(as expected with any post office) but since this one is small it makes it that much more busy. There is also a blue bin outside where you can drop off your letters and First Class packages(less than 16 oz) which will be picked up at the close of business. Hours: Mon-Fri: 10:00am-2:00pm. Sat-Sun: Closed. Even though the hours are limited, it’s nice to have a post office inside the hospital… if you really need something mailed out and you’re at work, this is a great convenience! Staff is friendly and the line usually moves quickly.(so long as no one holds it up!)
