Good local post office. I come here a few times a week to mail things. Staff friendly and efficient.


Great post office. Super Helpful. I have always found the people behind the front counter very friendly and take their time when waiting on you. I have dealt with the back office and they are also, very, very cooperative and helpful. Quaint post office in a lovely location.


I live 3 mins away from my post office and I get my mail at 7pm and sometimes never. This is ridiculous. My post office Is NORTHPORT post office. Long Islands worse post office. I’ve called and complained. Problem gets fixed for 2 weeks. The. Then it’s back to bad delivery time!!! Worse delivery service ever, bar none!!


Super rude, unfriendly and not helpful. Phone line not working to ask questions prior to going.


I have just discovered this site and would like to echo the Old Fisherman in saying we residents are very grateful the post office has remained open. We are a walking community and many can't access other locations. Also, the employees are as nice as has been said. They embody the spirit of the village.


Then let me be the first since noone has commented. Thank you for keeping this location open. The people that work here are some of the nicest people I know. They go out of their way to help an old WW2 veteran as well as the other people in Northport. The building is part of the locale and I hope the location remains as long as I live.
