Prison Mail Rules: What You Can and Can't Send

Every prison and jail sets its own mail rules, and they change often. But the same items get mail rejected almost everywhere. Knowing them saves you money, time and a disappointing returned envelope.

Usually allowed

  • Letters on plain white or lined paper, in blue or black ink.
  • A limited number of printed photos (see our photo guide).
  • Plain greeting cards at some facilities, usually without glitter, layers or electronics.
  • Printed pages like articles or recipes at some facilities, often with a page limit.
  • Books and magazines, but almost always only when shipped new from a publisher or approved retailer.

Usually not allowed

  • Stickers, glitter, glue, tape, labels, lipstick, perfume or any stains.
  • Crayon, marker, gel pen, colored pencil or anything that looks like a drawing medium.
  • Colored paper or envelopes, padded envelopes, cardboard, and staples or paper clips.
  • Cash, checks, money orders or gift cards inside a letter.
  • Polaroids, and any photo with nudity, weapons, drugs, alcohol, money or gang signs.
  • Blank paper, blank cards or blank envelopes, and often stamps.
  • Letters meant for someone else inside (third-party mail).
  • Anything about escapes, crimes, other inmates' cases, or the facility's security.

Tip: If a letter breaks one rule, the whole envelope is usually returned or thrown away. When in doubt, leave it out.

Digital mail scanning

Many prison systems and jails now route personal mail to an outside processing center that scans each page and delivers it to a tablet or kiosk. If your facility does this, send only what scans well: dark ink on white paper, and photos printed clearly. Anything that can't be scanned may be rejected.

How to find your facility's exact rules

  1. Look up the person with the state or federal inmate locator to confirm which facility they're in.
  2. Open that corrections department's website and search for "mail" or "correspondence."
  3. Look for the mailing address, any digital mail address, photo limits and the list of banned items.
  4. If anything is unclear, ask the person inside. They get the current rules at the facility.

Common questions

1.

Why was my letter returned?

The most common reasons are a missing inmate number, a missing return address, a banned item (stickers, colored paper, Polaroids, cash) or a wrong mailing address. Some facilities include a notice saying which rule was broken.

2.

Can I send money in a letter?

No. Money goes through the facility's approved deposit service instead. Cash in the mail is usually confiscated.

3.

Are the rules the same for jails and prisons?

No. County jails, state prisons and federal prisons each set their own rules, and jails are often stricter. Always check the specific facility.
