Key facts

Send mail to Ironwood State Prison, P.O. Box 2199, Blythe, CA 92226 — the institution's inmate-mail address, not its street address.
Ironwood State Prison is located at 19005 Wiley's Well Road, Blythe, CA, but inmate mail must go to the mailing address above — a letter sent to the street address can be returned.
California delivers inmate mail to each prison directly — but to the institution’s inmate-mail P.O. box, not its street address. Address it to the person’s full committed name, CDCR number, and housing/bed.
Several CDCR prisons use a different P.O. box for each housing facility (yard). Confirm the person’s current housing and use the matching box, or the letter is delayed.
Include your full name and return address. Mail without the correct CDCR number, or without a return address, can be rejected or returned.
Incoming personal mail is opened and inspected for contraband before it is delivered. Keep to plain letter-size paper; send copies of anything you are not willing to lose.
People are transferred between prisons without notice — check CDCR’s inmate locator for the current institution and housing before you mail anything.
PostPal prints and mails your letter for you the next business day for $5 — with your return address printed so the inmate can write back, and no printer, envelope, or stamp needed.

1
Confirm the person is still at Ironwood State Prison

Plain letter-size paper is safest. Do not enclose cash, stamps, gift cards, or any object other than paper — prohibited items get the whole letter rejected. Check the mail rules above before adding photos.
