Mail & Photos to Barnwell County Detention Center

Two Addresses, Two Purposes

Barnwell County Detention Center splits its incoming mail into two categories, each with its own address. Personal letters are routed through a third-party processing address in San Antonio, Texas, a common setup at jails that use a mail-scanning vendor, though the county’s site doesn’t name the specific vendor behind this address. Money orders, legal correspondence, and books shipped directly from a manufacturer go to the physical facility instead.

Personal Letters

Address personal letters to:

[Inmate's Name]
PO Box 2925

San Antonio, TX 78299-2925

Money Orders, Legal Mail, and Books

Address money orders, legal mail, and books shipped directly from the manufacturer to:

[Inmate's Name]
Detention Center
57 Wall Street
Barnwell, SC 29812

What Isn’t Published

The county’s site doesn’t name the vendor processing personal mail at the San Antonio address, nor does it specify a photo limit, package policy, or approved reading-material vendor list. If you’re planning to send photos, a package, or reading material beyond a standard letter, call the facility to confirm current rules before mailing anything.

What to Ask When You Call

• Are photos accepted in personal letters, and is there a limit?
• Are packages accepted, and if so, what’s the process?
• Do books need to come from a specific approved vendor, or is direct-from-manufacturer sufficient?
• Are there restrictions on paper, cards, or envelope types?

What’s Never Allowed Anywhere

Regardless of Barnwell County’s specific policy, some rules are universal across virtually every jail and prison: never mail cash directly to an inmate, and don’t include anything that could be mistaken for a prohibited substance or contraband, since that risks the entire letter being rejected or destroyed, and can create legal trouble for the sender.

If Your Mail Doesn’t Seem to Be Getting Through

If it’s been more than two weeks with no acknowledgment, call the facility to check on it. First confirm you used the correct address for what you sent, personal letters and money orders or legal mail go to two different places here, and sending to the wrong one is the most likely explanation if something hasn’t arrived.
