Mail & Photos to Trenton Correctional Institution

The Mailing Address

Address your letter to:

[Inmate's Legal Name, SCDC Number]
Trenton Correctional Institution
84 Greenhouse Road
Trenton, SC 29847

Always include your complete return address on the envelope.

Mail Is Opened and Inspected

Every piece of incoming mail at Trenton is opened and inspected before it reaches the inmate. This is standard across all SCDC institutions. Inspection can add processing time, so build that into your expectations if you’re sending something time-sensitive.

Photos

Photos are generally accepted as part of a letter. SCDC doesn’t publish a facility-specific limit on the number of photos per envelope on its public site, if you’re sending a large batch, call (803) 896-3000 to confirm there isn’t a per-envelope limit currently in effect.

Books and Magazines Require an Approved Vendor

Effective Oct. 1, 2025, SCDC requires that books and magazines come from an approved vendor, paid for in advance, with a receipt enclosed. You can’t mail a book you already own or one purchased secondhand.

Packages Go Through SCDC’s Inmate Package Program

Trenton is one of the facilities where SCDC packages products for its statewide Inmate Package Program, which lets family and friends order approved package combinations for shipment to an inmate anywhere in the SCDC system. This is a different process from mailing a package directly, you order through the program instead. Check doc.sc.gov/family for current package options and ordering steps.

What’s Never Allowed

Regardless of Trenton’s specific rules, some restrictions are universal at every SCDC institution and most facilities nationwide: never mail cash directly to an inmate, and never include anything that could be mistaken for a prohibited substance or contraband. Doing so risks the entire piece of mail being rejected or destroyed, and can create legal exposure for the sender.

If Your Mail Doesn’t Seem to Be Getting Through

If it’s been more than two weeks since you sent something with no acknowledgment, call Trenton at (803) 896-3000 to check on it. Mail flagged during inspection for any reason can be delayed or rejected, and a phone call is the fastest way to find out what happened.
