How Colorado inmate mail works
- Colorado sends mail to each facility directly. Address it to the incarcerated person’s full name and DOC number, then the facility’s own mailing address (a P.O. box for most, a street address for some).
- Include a valid return address. Mail without the DOC number or a return address can be rejected (governed by Administrative Regulation 300-38).
- Incoming mail is opened and inspected for contraband; generally only letters and photos are accepted — no packages or enclosed items.
- Confirm the person’s current facility on CDOC’s inmate locator before mailing — people are transferred without notice, and several Cañon City and Pueblo facilities share a mailroom, so the facility name on the envelope matters.
What you can't send
- Cash, checks, money orders, or postage stamps
- Anything other than paper letters and photos (no packages or enclosures)
- Nude, sexually explicit, or contraband-promoting content
- Stickers, glitter, glue, tape, perfume, lipstick, or crayon/marker
- Polaroids or laminated items
Photos: Photos are generally allowed; no polaroids or laminated photos, and nothing nude or sexually explicit.
Books & magazines: Books and magazines must come directly from an approved publisher or vendor (per AR 300-26), not in personal mail.
