How to put money on their books

Money on their account pays for phone calls, email, stamps, food and hygiene items from commissary. Get one detail wrong and the money bounces back or sits in limbo for weeks. Here is exactly how to do it.

Federal prison (BOP): the account number

Every BOP method uses the same account number: their 8-digit register number with no dash, followed right away by their last name exactly as the BOP has it.

Register number 12345-678, last name Smith12345678SMITH

Hyphenated or two last names are where families get stuck. The BOP doesn't always file a name the way the family writes it. Someone known as Jose Hernandez-Reyes may be on record as last name HERNANDEZ-REYES, or last name REYES with HERNANDEZ as a middle name. Our inmate search shows the name exactly as the BOP filed it and builds the account number for you.

Three ways to send it

MoneyGram and Western Union post seven days a week, including holidays. Sent between 7 a.m. and 9 p.m. Eastern, it usually posts in 2 to 4 hours; after 9 p.m., the next morning.

Mistakes that send the money back

A deposit problem? The BOP's deposit line is 202-307-2712, weekdays 8:00 a.m. to 4:30 p.m. Eastern. For a MoneyGram or Western Union transfer, call that company.

County and private jails (before BOP)

While the US Marshals hold someone, they're in a county or private jail, and that jail's rules apply, not the BOP's. Every jail picks its own company for deposits, and fees vary a lot.

Not sure which jail? Find the US Marshals office for the court; they can tell you where someone is held.
