Facility Mailing and Service Information
Texas Minimum Jail Standards Rule 291.2 requires every county jail to maintain an approved correspondence plan covering privileged and non-privileged mail.
Statewide rules allow inmates to send as many letters/pages as they desire and allow incoming correspondence in any quantity, subject to the jail's local security and property procedures.
This page uses the facility mailing address already associated with the jail record. Before mailing, include the inmate's full booked name and booking/inmate number if known, plus a complete sender return address. Verify any county-specific envelope, scanning-vendor or enclosure rules with the Sheriff's Office.

Texas statewide jail standards do not establish one universal photo size or quantity limit for every county jail. Photo rules are set in the facility's local correspondence/property plan.
Before sending photos, confirm the county's current quantity, size, Polaroid/self-developing-photo and content restrictions. Avoid sexually explicit, gang-related, weapon/drug-related or contraband-related images.

Texas county jails can apply local publication and package rules. The statewide correspondence standard does not create one publisher/source rule that applies identically to every county.
Confirm with the Sheriff's Office whether books must come directly from a publisher/retailer, whether hardcover or used books are prohibited, and whether packages require pre-approval.
