I have received a few phone calls from people about the zip code for mailing letters to the NH State Prison for Men in Concord. Some say it is 03301 and others think it is 03302.
Well....they're both right. One is for the physical location and the other is for the post office box.
Letters mailed to the physical location of 281 North State Street, Concord, NH, should have 03301.
Letters mailed to P.O. Box 14, Concord, NH must have 03302. All Concord, New Hampshire Post Office boxes are at the 03302 location, which is Loudon Road, Concord where the Post Office is situated. A prison mail officer goes over there mornings to pick up the mail. It is STRONGLY RECOMMENDED that you use the PO Box to mail letters to inmates.
So if your mail has been delayed it could be due to the improper zip code.
Remember - 281 North State Street - 03301
PO Box 14 - 03302
