Horrible post office, if you're a berwick resident from anything from 20+ years they don't care, they won't deliver your packages just because they don't feel like. They laugh every time I yell at them for sending a package back and they tell me "don't order so much". Reported to inspector general and talked to the regional as well, hopefully these postmasters get fired.


The South Berwick Postmaster went above and beyond to find a missing package for us. It was amazing that he took the information and didn't stop until it was located!! Thank you so much Steve!!


I deliberately leave my home town of South Berwick to do my USPS service at the Dover, NH or Eliot, ME locations. In the 4 times I've been to the South Berwick location I've had less than polite experiences. I waited 20 minutes behind one customer who had to weigh several boxes and bicker over rates while 2 other employees chatted behind the counter out of sight. The person at the counter didn't acknowledge me or even say "we'll be with you momentarily", nothing. No manners. My husband went in a couple weeks ago, 20 minutes before close. Again, trapped in line. At 4:25 another customer walked in the door, to which the postal worker hollered "WE ARE CLOSING!" Rude. Today, one came out made eye contact with my husband, continued chatting with his coworker, then eventually spoke to my husband who just popped in to ask about a passport package. Despite the website saying they offer this service, they said they don't. THIS is why people don't want to deal with USPS. Thank god I have 2 WONDERFUL offices nearby, who are friendly and appreciative of my business. There's a reason South Berwick isn't a 5-star location. I suggest employing people who actually want to do their job, rather than these schlubs.
