How to send a book to CSP-LA County — MSF

State prison · Lancaster, CA

⚠️ A prison has two addresses — only one delivers mail. Never mail to the facility's street address (that's the front gate — it comes back). The address below is the verified inmate mailing address. Put the person's full name and register number on the top line — that's what the mailroom matches on.

How mail works here

Softcover books only. Most facilities require books to arrive directly from a retailer or publisher — a used copy or one mailed from home often gets rejected. Address the label with the inmate's full committed name and register number so the mailroom can match it.
