Sending Mail to Someone at Monroe Detention: What Gets Through and What Gets Returned
Sending mail to someone at Monroe Detention is straightforward—if you get the details right. Miss a name or include something prohibited, and your envelope comes right back through the U.S. Postal Service.
All incoming mail at Monroe Detention gets inspected and delivered to inmates daily. Staff review everything before it reaches anyone inside.
Mail that doesn't meet the rules won't be held with the inmate's property. The entire piece gets returned through the U.S. Postal Service - back to you.
Always include your return name and address on the front of the envelope. Monroe requires this - skip it or write something unacceptable, and your mail comes back.
Use the inmate's complete first and last name - exactly as it appears in their booking record. Nicknames won't work. Mail addressed with a nickname gets returned marked "insufficient name" or "undeliverable as addressed."
Note: Gang monikers as the sender's name will get your mail returned marked "insufficient return name."

Sending reading material? Monroe has strict source rules. Newspapers, magazines, periodicals, and softbound books must come directly from a publisher or an internet website. Copies from retail bookstores or private individuals won't be accepted. Hardback books require Jail Commander approval.
Heads up: Unacceptable mail - whether due to contents or addressing issues - gets returned in full through the U.S. Postal Service.
Outgoing mail from inmates must be in standard white, business-size envelopes purchased through the inmate commissary.
Inmates must use this return address on all outgoing mail: Monroe Detention Center, 140A Tony Diaz Drive, Woodland, California 95776.
Troubleshooting Returned Mail Checklist
- ✓ Recheck the inmate’s name and use their complete first and last name exactly as it was used at booking (no nicknames).
- ✓ Make sure your return name and return address are written on the front of the envelope.
- ✓ Don’t use gang monikers as the sender name (mail may come back marked “insufficient return name”).
Got a newspaper, magazine, periodical, or softbound book sent back? Resend it the approved way - directly from a publisher or internet website, not from a retail bookstore or private individual. Hardback books need Jail Commander approval before Monroe will accept them.
