How to Send Mail to an Inmate at Dallas County Jail (Address, Legal Mail, and Prohibited Items)
Sending mail to someone at Dallas County Jail is straightforward once you know the exact address format and what items the jail won't accept. Here's the mailing address, how legal mail works, and what happens if your person gets released.
Use this address for all inmate mail to Dallas County: Inmate's Name and Booking (Book-In) Number c/o Mail Processing Center PO Box 9226 Seminole, FL 33775-9226
Don’t skip the booking number: Include the inmate’s full name and booking (book-in) number on the address. Missing or incorrect information can cause delivery problems.

Legal mail is opened in the inmate's presence. That's the standard handling process at Dallas County Jail.
