Federal inmate mail: how to send a BOP letter
Federal inmate mail
Federal inmate mail starts with BOP, not a random address search. The Federal Bureau of Prisons gives you the register number, custody status, and facility path you need before a personal letter makes sense.
The pulled U.S. flow already supports this path: it searches BOP records, fetches the facility mail address, and then opens the letter step.
BOP check
Verify the person before writing
BOP records can show released people, in-transit status, and many similar names. The register number is the cleanest way to reduce guesswork.
- • Search by register number when available.
- • Use exact name search only with extra verification.
- • Open the current facility page from the result.
- • Copy the correspondence address, not the funds address.

What this federal page helps with
- • Finding the BOP register number before writing.
- • Checking the current BOP facility and correspondence address.
- • Keeping a first letter plain enough for general correspondence.
- • Knowing when TRULINCS is a separate digital message path.
Before you continue
- • Search the BOP Inmate Locator by register number when you have it.
- • If you search by name, compare middle name, age, sex, race, facility, and register number before choosing a result.
- • Open the BOP facility page and use the correspondence address for inmate mail.
- • Do not send funds, packages, publications, stickers, or glitter with a regular personal letter.
- • Treat IN TRANSIT, Released, or Not in BOP Custody as a warning to verify the current destination.
Do not mix BOP mail paths
These paths can look similar to families, but BOP treats them differently.

Frequently asked questions
How do I find a federal inmate address?
Use the BOP Inmate Locator. It can search by register number or exact name. Name searches can return similar people, so verify the register number and facility.
What goes on a federal inmate envelope?
Use the full committed name, BOP register number, and the facility correspondence address from the BOP facility page.
Should I use TRULINCS instead?
TRULINCS is the BOP's electronic messaging system for approved contacts. A physical letter is still useful when you want paper mail or when digital contact is not set up.
Can I send money or books with the letter?
No. Funds, publications, packages, and special mail have separate BOP instructions. This page is for regular personal correspondence.
