How to Send Mail and Photos to California State Prison, Corcoran

Correct Mailing Address

Write the person’s full legal name and CDCR number on the first line.

[Full Legal Name] [CDCR Number]
[Full Legal Name] [CDCR Number], the housing-unit P.O. Box, Corcoran, CA 93212

Corcoran uses a separate P.O. Box for each housing facility, all in Corcoran, CA 93212:

Housing Facility	P.O. Box
Facility 3A	3461
Facility 3B	3466
Facility 3C	3471
Facility 4A	3476
Facility 4B	3481
Facility Z (Minimum Support, Hospital, Firehouse)	3456

If you’re mailing to the institution generally, not a specific person, the address is P.O. Box 8800, Corcoran, CA 93212-8309.

Look up the person’s housing facility on CIRIS, then use the matching P.O. Box. Housing can change if the person transfers between facilities, so confirm at ciris.mt.cdcr.ca.gov before you mail anything, especially if a letter was recently returned.

Letters and Envelopes

• Use plain white envelopes. No glitter, stickers, tape, perfume, or crayon.
• Standard greeting cards are accepted if they follow the same rules.
• Do not include cash, stamps, or blank paper for the person to reuse.
• All non-legal mail is opened and inspected before delivery.

Photos

• Standard photo prints are usually accepted.
• No Polaroids and no photos taped together.
• Nothing explicit, sexual, gang related, or violent.
• You can also send digital photos to the person’s tablet through the prison messaging provider.

Books, Magazines, and Newspapers

• Books and magazines must generally come from an approved retailer or publisher.
• Confirm current publication rules before ordering. Some titles are disapproved.

Legal Mail

Legal mail is handled separately and is opened only in front of the incarcerated person. Mark attorney mail clearly as legal or confidential.

Mailing Prints to a Corcoran Housing Box

On your phone, you can write a letter or pick photos, and Pigeonly prints them and mails them to the person’s housing-unit box from the table above, like P.O. Box 3471 for Facility 3C. You won’t need a printer, envelope or stamps. It travels as regular mail, so it’s opened and inspected before delivery like any other letter.
