Two Mailing Addresses for RADF: When to Use the Phoenix P.O. Box vs. the El Centro Legal‑Mail Address

For personal (non-legal) mail to someone at RADF, use the Phoenix P.O. Box address exactly as published: Imperial County Jail, Incarcerated Person's Name, SPN# P.O. Box 247 Phoenix, MD 21131. Write the person's name and SPN number exactly the way the facility lists them. Leaving either one off can slow delivery or prevent the mail from reaching the right person.

For legal mail to RADF, use the El Centro address exactly as published: Imperial County Jail, Incarcerated Person's Name, SPN# 1328 Sperber Road, El Centro, CA 92243. The same rules apply here: the name and SPN number are what make the mail deliverable. Double-check both before you seal the envelope.

How to Address Mail

• ✓ Put the incarcerated person’s full name on the envelope.
• ✓ Include the SPN number.
• ✓ Match the address to the type of mail you are sending (personal mail to the Phoenix, MD P.O. Box, legal mail to the El Centro, CA address).

If you're sending something other than a standard letter, or you're not sure which address applies, call the facility first. Getting clarification up front is faster than having something returned or delayed.

RADF publishes two separate mailing addresses: a Phoenix, MD P.O. Box for personal (non-legal) mail, and an El Centro, CA street address for legal mail. Only use the legal-mail address when it actually applies. If you're sending something that might be treated differently than regular personal correspondence, call the facility to confirm which address to use.
