How to Send Mail to Someone at Clay County Jail (new third‑party address and legal‑mail rules)
Clay County Jail now routes incoming inmate mail through a third party to reduce the risk of contraband entering the facility. Because of this change, you need to use the correct address for the type of mail you're sending, or it will be rejected.
Clay County Jail has switched to a third party for processing all incoming inmate mail. The goal is to reduce the risk of contraband getting into the facility. What this means for you is straightforward: personal mail from friends and family goes to a different address than legal mail and certain other items.
Effective date: As of 2/24/2025, all mail must be sent to the specific addresses the jail lists. Mail sent to other addresses will be rejected.
Standard, non-legal mail from friends and family must go to the jail's PO Box used for third‑party processing: Clay County Jail, FL, PO Box 76550, Highland Heights, KY 41076. Include the incarcerated person's name and ID number on the address line so staff can match it to the right person.
- ✓ Inmate full name
- ✓ Inmate ID number
- ✓ Your full return address (on the envelope)
Reminder: As of 2/24/2025, standard friends-and-family mail must go to the PO Box listed for mail processing. Mail sent to other addresses will be rejected.
Stick to the jail's size limits. Incoming mail can be no larger than 8 1/2 x 11 inches (letter size) and no thicker than light card stock, since it needs to feed through a sheet‑fed scanner. All mail is opened and inspected (and may be read) for contraband or rule violations. If something isn't allowed, it will be destroyed and not returned.
Legal mail, packages, and publications go to the jail's physical address: Clay County Jail, 901 North Orange Avenue, Green Cove Springs, FL 32043. Mail from lawyers or other legal representatives, along with money orders, also goes to this physical address, not the PO Box.
Use the right address: As of 2/24/2025, this split matters. Mail sent to the wrong address can be rejected.
How to Address
- ✓ Inmate full name
- ✓ Inmate ID number
- ✓ Your return address (on the envelope)
Envelopes or contents that are too large or too thick may not be accepted. Clay County Jail limits incoming mail to letter size (8 1/2 x 11 inches), and everything must be no thicker than light card stock so it can go through a sheet‑fed scanner.
Date to remember: The updated mailing rules and addresses took effect on 2/24/2025.
As of 2/24/2025, mail must go to the correct address for its type: the PO Box for standard mail, the physical address for legal mail and other items. Anything received at the wrong address will be rejected.
Even when you use the correct address, all incoming mail is opened and inspected (and may be read) for contraband or rule violations. If contraband or a violation is found, the mail will be destroyed and not returned.
