What are the rules to writing an inmate a letter?

When writing to an inmate, it's important to include the inmate's full name, ID number, and the correct address of the correctional facility. Be sure to follow the facility's guidelines for content and format, avoid discussing prohibited topics like escape plans, and refrain from including any prohibited items like cash or stamps. Letters may be subject to inspection by prison staff, so it's advisable to be respectful and follow all rules and regulations.
