Where to Send Mail to Waukesha County Jail (and Which Address to Use)
Waukesha County Jail uses two different mailing addresses depending on what you're sending. Use the wrong one and your mail could be delayed—or sent back.
The jail separates mail into two tracks. Personal letters from friends and family go to a mail-scanning address - a P.O. Box in Phoenix, Maryland. Legal mail and anything related to inmate funds (checks, money orders) go to the jail's facility P.O. Box in Waukesha, Wisconsin.
Why two addresses? Personal mail goes through a scanning process, but legal mail and monetary items follow separate handling rules. That's why legal correspondence, checks, and money orders must go to the facility address - not the scanning address.
For personal (non-legal) mail, use this address. Include both the inmate's name and inmate number so it gets matched correctly: Waukesha County Jail, WI Inmate Name, Inmate # P.O. Box 247 Phoenix, MD 21131
Heads up: Don't send legal mail to the Phoenix, MD address - it will be returned to you, not forwarded. Also, physical (non-scanned) mail is only kept for 30 days.
If you accidentally mail a check or money order to the scanning address, the jail says it will be forwarded. But you're supposed to send checks and money orders directly to the facility address - doing it right the first time avoids delays and confusion.
For legal mail, checks, and money orders, use this address. Include the inmate's first and last name, plus their inmate number when required: Inmate's First and Last name Waukesha County Jail P O Box 0217 Waukesha, WI 53187-0217
- ✓ Send funds only as a certified check, cashier’s check, or money order.
- ✓ Do not send cash.
- ✓ Do not send personal checks.
- ✓ Don’t address inmate funds to a specific inmate - follow the jail’s deposit/addressing instructions so it will be accepted.
Common mistake: Legal mail sent to the Phoenix, MD scanning address gets returned to you - it won't be forwarded to the jail.
Common mistake: Cash and personal checks aren't accepted for inmate funds. Use a certified check, cashier's check, or money order instead. Follow the jail's addressing and deposit instructions - including not addressing funds to a specific inmate.
Yes, the jail says checks or money orders sent to the scanning address will be forwarded - but don't rely on that. Send them directly to the facility P.O. Box in Waukesha. Getting the address right from the start is the best way to avoid delays or misrouted payments.
