For families
When someone moves, the first question is often where to write
Federal incarceration can separate people from home by hundreds of miles. PieterPost turns the public lookup step into a family-contact flow: find the person, confirm the facility, then send a letter or photo while the address details are still in front of you.
A transfer can leave family members unsure where to send the next note.
A printed letter gives children, parents, and partners something simple to hold onto.
Finding the correct facility first helps avoid mail delays and returned envelopes.
Inmate lookup
Search for a prisoner
Enter an exact name or register number to find a federal inmate, confirm the facility, and start a letter or photo order.
Why this matters
Family contact starts with a correct address
