- GGGreenEyedMom69Dec 1, 20251.0I went in to the Portsmouth PO 11/29/25.The employee (man) was RUDE!! Crammed my item in a box that was clearly too small. When I asked him to “please” find a better sized box, his demeanor changed. Went out back, 2 people popped their heads out as if he was complaining about my request. Too bad, you get paid to do your job and be curtious to the customers. Never was I rude or unappreciative.
- LHLori HiltsOct 17, 20251.0Haven't received mail in Seabrook for THREE DAYS. Tried calling Portsmouth over a dozen times, two different numbers - no one answers. Seabrook post office says they have no control since mail delivery is handled through Portsmouth.
- DBDrew BaileyOct 17, 20171.0Not a post office, just a shipping and receiving facility.
- MAMelody AdamsMar 19, 20173.0Sorting Facility. Cannot go past the first parking lot. First parking lot contains 4 or 5 mail drop boxes that anyone can drive up to and drop mail off in.
- WLWesley LeFevreJan 12, 20163.0Do not use the parking lot!!!!!!! Use the street
