About MCC San Diego
MCC San Diego is a Metropolitan Correctional Center run by the Federal Bureau of Prisons in San Diego, California (San Diego County). The BOP lists its security level as Administrative and says it holds men and women. It is in the BOP's Western Region.
Visiting
You can only visit if the person has put you on their approved visiting list and the BOP has cleared you. The person mails you a Visitor Information Form after they arrive; you fill it in and send it back. Federal law gives each person at least four hours of visiting a month, and the warden can limit visit length or the number of visitors.
Visiting days and times differ by institution and can be cancelled for safety reasons. Read the MCC San Diego visiting regulations (PDF) and call 619-232-4311 before you leave. More in how to visit someone in prison.

Use the person's committed name (no nicknames) and register number. Letters are opened and inspected by staff, except specially marked legal mail. Packages from home need written approval first; books and magazines must come straight from the publisher. See how to send mail to an inmate.
Sending money
Never send money to MCC San Diego's address. All federal inmate deposits go through the BOP's national systems, whatever prison the person is in:
- MoneyGram (receive code 7932) or Western Union (code city FBOP, DC). The account number is the 8-digit register number with no spaces, then the last name (for example 12345678DOE).
- By mail: a money order or cashier's check (no cash or personal checks) to Federal Bureau of Prisons, the person's committed name and register number, Post Office Box 474701, Des Moines, Iowa 50947-0001.
Wait until the person has physically arrived at the BOP facility. Full steps in how to send money to an inmate.
Phone calls and email
Calls are monitored, and usually the person in prison pays for them. Email runs through TRULINCS: text only, up to 13,000 characters, and both sides must agree to monitoring. More in phone calls with someone in prison.
