Mail at California State Prison, Sacramento is simpler than at some other CDCR prisons. CDCR’s official facility page for CSP-Sacramento publishes one general P.O. Box for personal mail instead of splitting it by housing unit, the way facilities like California State Prison, Los Angeles County do. Address a letter to the person’s full legal name, their CDCR number, and P.O. Box 290001, Represa, CA 95671, and it should reach them regardless of which housing unit they’re currently in.
Unlike some CDCR prisons that split personal mail across several P.O. Boxes by housing unit, CSP-Sacramento’s official CDCR facility page lists one general address for personal mail:
[Full Legal Name, CDCR Number]
California State Prison, Sacramento
P.O. Box 290001
Represa, CA 95671
Always include the person’s full legal name and CDCR number. CDCR sorts mail internally once it reaches this address, so you don’t need to know the person’s specific housing unit to address a letter correctly here.
CDCR also lists a second P.O. Box, 290002, for the Warden’s Office at Represa, CA 95671. That address is for staff and administrative business, not personal letters to an incarcerated person. Sending a personal letter there instead of the general P.O. Box 290001 can delay it reaching the person you’re writing to.
People do get transferred between CDCR institutions. Check CIRIS at ciris.mt.cdcr.ca.gov, or ask the person directly, to confirm they’re still at CSP-Sacramento before you send a letter, especially if some time has passed since you last heard from them.
Standard letters, greeting cards, and photos are generally accepted. Keep to plain paper and cards without stickers, glitter, tape, or anything glued on, since those items get mail rejected.
Photos are generally allowed within CDCR’s limits: no Polaroids, since the backing can conceal contraband, and nothing larger than 8x10. Avoid nude or sexually explicit images, gang-related content, and anything depicting drugs or weapons, which will be rejected. There’s usually a limit on how many photos per envelope, so send a reasonable number and confirm current limits with the institution if you plan to send many. You can also send photos through Pigeonly without printing anything yourself. Upload the photos online and Pigeonly prints and mails them to CSP-Sacramento for you.
Legal mail from an attorney, court, or public official should be clearly marked as legal mail on the outside of the envelope. It’s opened only in the presence of the incarcerated person to check for contraband, not read. If you’re an attorney or a legal representative, confirm CSP-Sacramento’s exact legal-mail handling by calling (916) 985-8610, since the facility’s public page doesn’t publish a separate legal-mail box distinct from the general address.
Incoming personal mail is opened and inspected for contraband before delivery. If a piece is rejected, the person is typically notified and told why, and the item may be returned to sender or held. Following the plain-paper, no-attachments rules is the best way to avoid a rejection.
You can’t mail a personal package straight to the person. Approved packages, including quarterly packages, come through CDCR’s contracted package vendor, which the person or an approved family member orders from. Contact the institution at (916) 985-8610 or check CDCR’s approved vendors page for the current process.
Don’t mail cash. Use an electronic deposit through GTL/ConnectNetwork, JPay, or Access Corrections, or send a check or money order following the process on the CDCR send-money guide.
