Allegheny County Jail

Can you send letters /cards

Yes, you will need the inmate's DOC#, the jail will not provide this to you, you will need to get it from the inmate, which will be put on every letter to the inmate, the format should be:
ALLEGHENY COUNTY JAIL
"Inmate's name"
DOC #(Inmate's Doc number"
950 SECOND AVENUE
PITTSBURGH, PA 15219

On a side note photos are allowed too, but no more than 5 in a letter at a time. Do not mail books or magazines, they will need to come directly from a publisher, the only exception would be if you ordered it from like Amazon.com or Barnes and Nobels.com (internet book retailer). If you are not sure talk to a counselor at the jail.
