How to Address Mail to Someone at Decatur Correctional Center
Getting the address right matters—especially the P.O. Box and IDOC number. Use the format below so your letter reaches the right person at Decatur Correctional Center.
When sending personal mail to someone at Decatur Correctional Center, address the envelope to the facility's P.O. Box - not the street address. The business mailing address is 2310 East Mound Road, P.O. Box 3066, Decatur, IL 62524, but mail for an individual in custody goes to P.O. Box 3066, Decatur, IL 62524. Include the person's full name and IDOC number on the envelope. Staff use this information to match mail to the correct individual.
Example: Write it like this on the envelope: Individuals in Custody Name & IDOC# P.O. Box 3066 Decatur, IL 62524
Put the IDOC number right next to the person's name - either on the same line or directly below it. The format doesn't matter as much as making sure both the name and IDOC number are clearly visible on the address.
Sending books, magazines, or newspapers? Plan ahead. Beginning September 30, 2025, publications will only be accepted if mailed directly from the publisher. Visitors won't be allowed to drop off publications at the facility.
Photos are an exception. Original photographs mailed directly from a photo printing vendor will be delivered - even if they have the vendor's watermark or logo - unless the photos are otherwise unauthorized.
Time Sensitive Confirmation
- ✓ Double-check that the envelope includes the individual’s name and IDOC number.
- ✓ If you need confirmation, consider using a mail service with tracking and keep your tracking number.
- ✓ For questions or follow-up, call or fax the facility with the details you have (including the person’s name and IDOC number).
