Who Can Send Letters to Inmates?

06/02/2026

Understanding correspondence eligibility is crucial for staying connected. Here is a breakdown of who can and cannot send mail to a U.S. prison facility:

  • Relationship Status: In most U.S. Federal (BOP) and State (DOC) prisons, you do not have to be a relative. Friends, mentors, and pen pals are allowed to write, though some high-security facilities may limit mail to an approved list.

  • Age Limits for Minors: Anyone 18 or older can freely send mail. However, minors under 18 generally cannot write to an inmate without the express written consent and supervision of a parent or legal guardian.

  • Restricted Individuals: Inmate-to-inmate correspondence is strictly prohibited unless given rare, special permission by both wardens. Additionally, co-defendants or victims of the inmate's crime are banned from sending mail to avoid witness intimidation..
