What to Put on the Envelope: Return Address Requirements for Outgoing Mail from Inmates

When someone sends a letter from jail, the return address needs to be complete and formatted exactly how the facility wants it. Otherwise, the letter might not go out.

• 1 min read Verified from official sources

All outgoing letters need a full return address. This means the inmate's full name exactly as it appears in jail records, plus the facility address: Grant County Detention Center, 320 Ridge Road, Silver City, NM 88061. If the name is shortened or doesn't match what's on file, processing slows down. Double-check the spelling and use the full legal name before the envelope goes out.

Letters missing a complete return address won't go out right away. Staff will hold the mail until the sender is identified and the return address is corrected. For time-sensitive letters, this delay can be a real problem.

Warning: Any markings on the envelope beyond the return address and delivery address can trigger an inspection. Mail with extra markings may be returned instead of sent out.
