How to Send Mail to York County Prison: P.O. Box, TextBehind, Legal Mail Rules, and Denied-Mail Pickup
Sending regular (non-legal) mail to York County Prison? Don't use the prison's street address. Standard mail must go through the facility's vendor process—specifically TextBehind—rather than directly to the prison. (GTL tablet messaging is also available for communication.) Always include the incarcerated person's full name and ID number on the envelope so it gets matched correctly during processing.
