How to Mail Letters and Photos to Someone at Grant County Jail (addresses, format rules, and photo limits)
Mail for someone at Grant County Jail goes to different addresses depending on what you're sending. Regular friends-and-family mail is addressed to the PO Box in Highland Heights. Legal mail (from a lawyer or legal representative) goes to the street address on Barnes Road in Williamstown. The jail warns that mail sent to other addresses can be rejected, so double-check before you drop anything in the mailbox. One thing to watch for: the Barnes Road street address appears online with a different ZIP code than the one shown in the mail-instructions PDF. Verify the correct ZIP for legal mail with the facility before you send it.
