How to Mail Original Documents for an Inmate to Sign at St. Charles County DOC
Need an inmate at St. Charles County DOC to sign an original document—like a Power of Attorney or vehicle title transfer? Mail it using the county's specific format so it goes directly to the caseworker, not through regular mail processing.
Some paperwork requires a wet signature on the original document. St. Charles County DOC calls these "transactional documents" - things like a Power of Attorney or vehicle title transfer. These must be mailed as originals using their caseworker routing format so the inmate can review and sign.
Use the county's exact addressing format so your document gets routed to the caseworker. Include the inmate's name and inmate number, then address it "C/O Caseworker" at 301 N. Second Street, St. Charles, MO 63301. This is different from regular personal mail - it's the direct-to-jail format for originals that need staff handling.
Use this address format: SCCDOC - Inmate Name/Inmate Number, C/O Caseworker, 301 N. Second Street, St. Charles, MO 63301.
Adding "C/O Caseworker" to the envelope routes your document through the caseworker process. The inmate can then review and sign it. This is a separate handling path from everyday mail - use it for any original that requires a signature.
Personal (non-legal) mail doesn't go directly to the jail. It's sent to a central processing facility (JailATM), where staff opens it, scans it, and delivers it electronically to the inmate.
Legal mail works differently. The central processing facility won't open it - if legal mail ends up there, it gets returned to sender. That's why legal mail and official documents should go directly to St. Charles County Department of Corrections at 301 N. Second Street, St. Charles, MO 63301, with the inmate's name included.
Practical Tips
- ✓ Put the inmate’s full name and inmate number on the address (and keep it consistent across anything you include)
- ✓ For originals needing a signature, address it exactly as: SCCDOC - Inmate Name/Inmate Number, C/O Caseworker, 301 N. Second Street, St. Charles, MO 63301
- ✓ For legal mail and official/business documents, mail directly to: St. Charles County Department of Corrections, Inmate Name, 301 N. Second Street, St. Charles, MO 63301
- ✓ Use a traceable shipping method if you need proof of delivery
- ✓ Make and keep copies for your records before you mail the originals
- ✓ Plan for processing time - there isn’t a published timeline for how quickly signed originals will be handled and returned
Keep in mind: There's no published turnaround time, so don't plan around a specific deadline. Make copies of everything and use a trackable shipping method for your originals.
