How to Send Mail to an Inmate at Brown County Jail (New JailATM Address)
If your mail keeps getting returned, you're not alone. Brown County Jail changed how personal mail works, and the old address no longer works. Here's how to send mail the right way so it actually reaches your loved one.
Starting October 6, 2025, all personal mail for Brown County Jail (WI) must go to an off-site JailATM.com processing address - not to the jail itself. Send it directly to the jail after that date? It'll be returned, even if everything else on the envelope looks correct.
What does "processed off-site" actually mean? Your letter gets opened at a JailATM.com mail facility, scanned, and delivered digitally to the inmate at Brown County Jail. You still write a normal letter - your loved one just receives a digital version instead of the original paper.
Warning: Personal mail sent to the jail (instead of the JailATM.com address) will be returned to sender, and parcel packages aren’t accepted for inmates and will be rejected and returned.
Address personal mail exactly like this so it routes correctly through JailATM.com: JailATM.com Brown County Jail, WI Inmate Name and ID Number P.O. Box 16120 Jonesboro, AR 72401
- ✓ Put the inmate’s full name and ID number on the envelope.
- ✓ Include your return address so it can come back to you if it’s rejected.
- ✓ Send personal mail only to the JailATM.com P.O. Box (personal mail is opened, scanned, and delivered digitally).
- ✓ Don’t send parcel packages - they won’t be accepted.
Legal mail works differently. It must go directly to Brown County Jail and come from a licensed attorney of record. Business and transactional documents - like checks and money orders - also go straight to the jail, addressed to the Brown County Jail Business Office at the facility's street address.
Don’t mix these up: Checks, money orders, and other business/transactional documents should go to the jail’s Business Office (street address), not to the JailATM.com personal-mail P.O. Box.
Prohibited Senders
- ✓ Victims of the inmate’s crime
- ✓ Current inmates
- ✓ Former inmates
- ✓ Parolees
- ✓ Probationers
- ✓ Co-defendants
- ✓ Current or former jail employees
- ✓ Current or former contract employees
- ✓ Current or former volunteers
- ✓ Anyone with an active Protection from Abuse Order against the inmate that prohibits contact
If you fall into one of the prohibited categories above, the jail won't deliver your mail. The correspondence simply won't make it through.
Brown County Jail doesn't accept parcel packages for inmates - they'll be rejected and returned. After October 6, 2025, personal mail addressed directly to the jail (instead of the JailATM.com address) will also come back to you. Double-check the address before you drop it in the mailbox.
Tip: Keep it simple - send personal mail as a standard letter in a flat envelope and use the exact JailATM.com address format to avoid a return.
Sending something time-sensitive? Confirm you're using the current instructions first. The policy change takes effect October 6, 2025, but older documents may reference different vendors or processes. A quick verification saves you a returned letter.
