FDC Philadelphia is a federal detention center, so most of the men and women here are waiting on a trial date or a sentencing date instead of serving a long sentence. That changes the search in two ways. First, the Federal Bureau of Prisons (BOP) locator lists federal inmates only, so someone held on Philadelphia city charges or on a Pennsylvania Department of Corrections (PA DOC) state sentence won’t be here. Second, someone arrested on federal charges yesterday may still be in U.S. Marshals Service custody and not yet booked into the BOP system, which can take a few days.
Search the 8-digit federal register number when you have it, since it survives every transfer and it’s the number required on mail and on deposits. Otherwise use the name from the court docket and try middle names and alternate spellings. Then check again, and keep checking. People move out of a detention center quickly, whether that’s a release, a transfer to a designated prison after sentencing, or a temporary court trip. If the result stops matching what you were told, call (215) 521-4000 and ask.

Detention center populations turn over fast. He may have been sentenced and designated to a prison, released, or moved for a court appearance. Search his register number to see his current facility, then call (215) 521-4000 if the result doesn't make sense.
Inmate SearchIt depends what you're sending. Letters and photos for the person go to his full name and register number at FDC Philadelphia, 700 Arch Street, Philadelphia, PA 19106. Questions about his trust fund account go to Inmate Accounts, PO Box 572, Philadelphia, PA 19105, which is a separate address and not where deposits go.
Inmate SearchPeople are often held by the U.S. Marshals Service for a few days before the BOP books them into a detention center. Keep checking the locator, and call (215) 521-4000 if several days pass with no record.
Inmate SearchYes. FDC Philadelphia holds people awaiting trial and sentencing, and they appear in BOP records with a register number the same as sentenced inmates. What's different is how fast the record can change, so confirm before every visit or deposit. A quick call to (215) 521-4000 tells you if he's still at 700 Arch Street.
Inmate SearchNot here. The BOP locator that covers FDC Philadelphia lists federal inmates only, and it doesn't reach the city's own jail system or the Pennsylvania Department of Corrections (PA DOC). If you're unsure which system arrested him, the court paperwork will say federal or state. Staff at (215) 521-4000 can speak only to people in federal custody.
