How to Write to Inmates: Prison Mail Tips

Tip 01

Check the Facility's Rules First

Every prison, jail and detention center has its own mail policies. These rules can change at any time and what's allowed in one facility may be banned in another. Always review the facility's website or contact their mailroom before sending anything.

Tip 02

Keep Your Letter Simple and Clean

Most facilities only accept plain white or lined paper, blue or black ink and standard envelopes. Avoid stickers, glitter, colored paper, drawings with heavy marker, or scented items — these are common reasons mail gets rejected.

Tip 03

Avoid Gel Pens or Colored Ink

Many facilities reject letters written in gel pens, metallic ink, or brightly colored pens because they cannot be scanned properly or may be considered a security risk. Stick to standard blue or black ballpoint ink.

Tip 04

Photos Have Strict Rules

Many facilities allow a small number of printed photos, but they must follow strict content guidelines. Photos cannot include nudity, gang symbols, hand signs, weapons or anything considered inappropriate. Polaroids are almost always rejected.

Facilities in Florida, Texas, Georgia, Indiana, Ohio, New Mexico, West Virginia and Alabama have implemented mail-scanning vendors — meaning all physical photos are scanned and originals are at risk of being destroyed. Some facilities do not allow photos at all.

Tip 05

Do Not Send Money Orders, Checks, or Cash

Most prisons will reject any form of money sent through the mail. Cash, personal checks, and money orders are typically returned or destroyed. To add funds, use the facility's approved deposit system — usually an online service, kiosk, or a designated mailing address specifically for financial transactions.

Tip 06

Avoid Any Content That Could Be Viewed as a Threat

All incoming mail is screened or read by staff. Anything that could be interpreted as a threat may cause your letter to be rejected. Avoid discussing violence, escape plans, weapons, illegal activity, security procedures, or anything that could endanger the facility, staff or other incarcerated individuals.

Tip 07

Address the Envelope Exactly as Required

Include the incarcerated person's full legal name, ID or DOC number, housing unit (if known) and the facility's complete address. Missing or incorrect details can cause mail to be returned.

Tip 08

Ask the Person You're Writing for Guidance

They often know the most up-to-date rules for their facility. If you're unsure about something — photos, stamps, content, or formatting — they can usually tell you what's allowed and what gets rejected.
