This is a private reference site, not a Costilla County office. We cannot confirm whether someone is in custody, release a person, post bond, schedule a visit, or pull an official booking record. For those actions, use the government office or locator that controls the record.

Use the match below before calling or writing, because Costilla County jail custody, court records, prison custody, and federal or immigration detention are separate systems.
- For a person recently booked into the county jail, start with jail inmate records and the Costilla County Sheriff's Office.
- For booking-photo access, review jail roster mugshots and Colorado booking-photo limits under C.R.S. 24-72-305.5.
- For charges, hearings, and filings after an arrest, use court records after a jail arrest and Costilla Combined Court.
- For a facility-specific question, use the Costilla County Jail, Conejos County Jail, and Las Animas County Jail pages linked in the footer.
- For a sentenced Colorado prisoner, search the Colorado Department of Corrections Offender Search.
- For federal custody or immigration detention, use the BOP inmate locator or ICE Online Detainee Locator System. VINELink can also help with custody-status notifications where available.
