Putting money on a loved one's books is one of the most direct ways to improve their daily life inside. Commissary funds cover phone calls, food supplements, personal care, and the small daily necessities that make incarceration more bearable. But every facility uses specific approved money transfer services and sending money through an unapproved channel means delays, fees, or the money not arriving at all. This section covers which money transfer services are approved at federal and state facilities, how to find the right service for a specific institution, how long transfers take to post, deposit limits and frequency restrictions, how to send money from outside the United States, and what to do when a transfer does not post as expected. The practical guidance here is built around getting money where it needs to go efficiently and without unnecessary fees. See also our sections on Commissary, Money Transfer, and Inmate Phone Calls.
