- SFSteven FMar 19, 20265.0Friendly and helpful staff every time I have been here. Thank you.
- EBElizabeth BrownJan 26, 20265.0I’m surprised by these reviews because I personally have had nothing but great experiences with Merrimack post office. Yes, I get random mail inserts but I feel as though that’s the norm everywhere. I really want to shout out Beth because I had a package that was going to be delivered late due to the snow storm. I was getting no updates on the location. I submitted a request to find my package and Beth called me personally to give me updates. She even called me during the snow storm to tell me she had the package and it would be delivered the next day. Thanks for the great customer service!

- JIJa IJul 5, 20231.0Ignorant, rude, disgusting behavior from the post master Kathleen.
- BCBrian CampbellApr 25, 20225.0I ship books from this Post Office all the time, and am always impressed with the service. This is an excellent group of people and it's a pleasure doing business with them.
