Colorado inmate mail
Send a letter to an inmate in Colorado
Colorado mail goes to the current CDOC facility, but photocopy rules can vary by institution. Confirm the DOC number, address, and current mail notice first.

Use the current Colorado facility address
Colorado personal mail is facility-direct. Confirm the person’s current CDOC location and use that facility’s official inmate-mail address, then check whether its current notice requires photocopy delivery.
Colorado’s photocopy restriction can change by facility. Check the current CDOC contact page before mailing.

Helpful inmate-mail rules
- Letter length
- No universal short page limit applies to normal letters; check the facility before sending an unusually long letter
- Letter format
- Use plain white paper and dark ink so the letter remains legible if the facility photocopies it
- Envelope and address
- Use the full committed name, DOC number, current facility mail address, and a complete sender name and return address
- How it arrives
- The current facility may deliver the accepted original or a photocopy under a facility-specific contraband restriction

Common questions
How do I send a letter to an inmate in Colorado?
Confirm the person’s DOC number and current facility, then copy that facility’s inmate-mail address. Write online and PieterPost will format, print, add the envelope and postage, and mail the physical letter.
Which address should I use for Colorado inmate mail?
Use the inmate-mail address published for the person’s current CDOC facility. Colorado does not provide one statewide address, and a private or contract prison may publish additional instructions.
How do I find a Colorado DOC number and facility?
Search the Colorado inmate locator for the person’s record, DOC number, and current location. Then use CDOC’s facility list to find the correct mail address and recheck it after a transfer.
Will the recipient get my original Colorado letter?
Delivery depends on the facility’s current restriction. A facility subject to CDOC’s contraband-related photocopy rule may give the recipient a copy, while another may deliver the accepted original. Treat every original as replaceable.
Does this guide apply to Colorado jails or federal prisons?
No. It covers adults in CDOC state-prison custody. County and city jails, federal prisons, juvenile facilities, and private or contract facilities may use different mail routes or added rules.
