How to Send Mail to Someone at Clay County Jail (why standard mail now goes to Kentucky and where to send legal mail)
Sending mail to someone at Clay County Jail is straightforward once you know the right address. Standard personal mail now goes through a third-party processor in Kentucky, while legal mail and a few other items still go directly to the jail.
Clay County Jail uses a third party to process all incoming inmate mail. The jail says this change is meant to reduce the risk of contraband entering the facility, so the address you use depends on what you’re sending.
Standard mail from friends and family goes to the jail's processing center in Kentucky. Include the inmate's name and inmate ID number on the envelope, then use this address: Clay County Jail, FL, PO Box 76550, Highland Heights, KY 41076. Missing the name or ID? Your letter probably won't reach them.
Remember: Put the inmate’s name and inmate ID number on every piece of mail you send.
Not everything goes to Kentucky. Legal mail, packages, publications, and money orders should be sent directly to the jail. Include the inmate's name and inmate ID number, and address it to: Clay County Jail, 901 North Orange Avenue, Green Cove Springs, FL 32043.

- ✓ Include a return address on the envelope
- ✓ Keep pages no larger than 8.5" x 11" (letter size)
- ✓ Don’t send anything thicker than light card stock

Why the strict format limits? All incoming mail runs through a sheet-fed scanner. Anything oversized, too thick, or awkwardly shaped won't feed through cleanly - and gets rejected.
