How to Send Mail to Someone at Guadalupe County Jail: Privileged Mail vs. Viapath (Two Addresses)
Guadalupe County uses two different mailing addresses depending on what you're sending and who it's from. Pick the right one and label your envelope correctly — your mail will have a much better chance of reaching your loved one without delays.
"Privileged mail" gets special treatment. At Guadalupe County Adult Detention Center, this includes mail from courts, government officials, news media, and attorneys. Staff will only open privileged mail in front of the inmate, and they're just checking for contraband - not reading the contents.
If you’re sending privileged mail, address it to Guadalupe County Adult Detention Center at 2615 N Guadalupe St, Seguin, TX 78155.
If you’re sending non-privileged mail (regular personal letters), it must go to the facility’s mail vendor, ViaPath, at PO BOX 247, Phoenix, MD 21131.
Regular letters sent to ViaPath don't arrive at the jail as paper. ViaPath scans everything and forwards it digitally to the facility, where it's delivered to your loved one electronically.
Practical takeaway: For non-privileged mail, think “digital delivery.” Your letter is scanned and forwarded electronically for inmate delivery, so it won’t be handed over as the original paper you mailed.
Skip the printed photographs. Guadalupe County Adult Detention Center doesn't accept physical photos, and the facility won't print them out. Instead, photos get scanned and delivered digitally.
What to Put on Envelope
- ✓ Sender’s full name
- ✓ Sender’s complete return address
- ✓ Inmate’s full name (the name used at booking)
- ✓ Inmate’s SO number
If your scanned mail doesn't seem to be getting through, contact the mail vendor's support team at info@textbehind.com for help troubleshooting.
