Costilla County Jail Inmate Lookup

Costilla County Jail Overview

Costilla County Jail is tied to the Costilla County Sheriff's Office campus in San Luis. The research file identifies the official detention function as the Costilla County Jail / Costilla County Sheriff's Office, operated by the sheriff. The current sheriff page lists Joe Smith as Sheriff, while older official sheriff PDFs still carry prior leadership names. For present-day jail contact and records routing, use the current sheriff page and the published sheriff contact block.

The facility is a county jail, not a state prison, federal prison, or immigration detention center. It is the local starting point for people arrested by the Costilla County Sheriff's Office, Blanca Police Department, Colorado State Patrol, or another agency and presented for local custody. The jail population can include pretrial detainees, people awaiting advisement or bond review, people waiting for transfer, and people serving short local sentences as allowed by Colorado law. A person sentenced to Colorado prison should be searched through the Colorado Department of Corrections, not through the local jail.

Costilla County Jail Capacity and Population

The strongest population source in the research file is the Vera Institute Incarceration Trends county dataset for Costilla County, FIPS 08023, accessed June 1, 2026. Those figures should be treated as historical trend data rather than live jail counts. The research did not locate a current county-published rated capacity, current average daily population, jail handbook, or daily booking report. Vera's recent rows show zero or blank values in several 2024 and 2025 fields, and the research specifically cautions that those rows likely reflect a reporting gap or changed reporting rather than proof that no jail custody occurred.

How to Look Up an Inmate at Costilla County Jail

No official public Costilla County Jail roster or recent-bookings page was located. The practical lookup path is therefore a fallback chain: start with the sheriff's phone and records channels, then check court, prison, federal, immigration, and victim-notification systems based on the person's custody stage. For a general overview of local record access, see Jail Inmate Records.

1. Call the Costilla County Sheriff's Office at 719-672-0673 or dispatch at 719-672-3302. Ask whether the named person is currently in Costilla County Jail, recently released, or transferred.
2. Have the person's full legal name, date of birth or approximate age, and arrest date ready. If the person was booked under a different name, tell staff about the possible variation.
3. If phone confirmation is unavailable or not enough, submit a written Sheriff's Office records request by email to costillacountyco@gmail.com, by mail to Attention: Records Request, P.O. Box 6, San Luis, CO 81152, or in person at 103 Gasper or Gaspar Street in San Luis.
4. Check Colorado Judicial Branch dockets for a court appearance after the arrest. A docket is not a jail roster, but it can show that a criminal case or hearing exists.
5. If Costilla says the person was housed out of county, call the named receiving jail. The research file identifies Conejos County Jail and Las Animas County Jail as official Costilla housing discussion or agreement locations in 2025.
6. If the person has been sentenced to state prison, use CDOC Offender Search. If the matter is federal, use BOP or federal court channels. If immigration detention is possible, use ICE ODLS and attorney or ICE contacts.

Costilla County Jail Address and Contact

The Costilla County Sheriff's Office is the local custodian for jail booking, custody, and population questions identified in the research. The official sheriff materials use the address spelling Gasper in several places, while one current records section uses Gaspar for the in-person location. Use the official address block when mailing and confirm the spelling when using a map or delivery service.

Map and Directions

Use 103 Gasper Street, San Luis, CO 81152 as the map address because that address appears in official sheriff materials. Costilla Combined Court is listed separately by the Colorado Judicial Branch at 304 Main Street, P.O. Box 301, San Luis, CO 81152. Jail custody questions and court-case questions can require different counters, so confirm the destination before traveling.

Visiting Someone at Costilla County Jail

The research file did not locate an official Costilla County Jail visitation schedule, video-visit vendor, appointment system, dress code, minor-visitor rule, or visit-length rule. Do not rely on a schedule from another jail. Conejos County Jail has its own published weekend visitation schedule, but that schedule applies only if the person is actually housed at Conejos. For Costilla County Jail, call the sheriff or dispatch number before traveling and ask whether visits are currently allowed, whether they are in person or remote, and whether an appointment is required.

Mail, Phone, and Money at Costilla County Jail

Official Costilla-specific inmate mail format, commissary vendor, phone vendor, video vendor, deposit fees, and money-order rules were not found in the research file. The Sheriff's Office address and P.O. Box are available, but that is not the same as a confirmed inmate-mail format. Before mailing anything, sending funds, or setting up a phone account, call the jail and ask for the current inmate name line, booking or ID requirement, approved envelope or postcard rule, prohibited items, and vendor name if one is in use.

Booking and Intake at Costilla County Jail

Costilla-specific written booking procedures were not located, so the local page should use careful Colorado process language. A person arrested in Costilla County may be brought to the jail or sheriff campus for identification, warrant checks, fingerprints, property inventory, safety screening, charge entry, and bond or hold review. A booking photo may be taken during intake, but no official public Costilla booking-photo gallery was located. Later court charges can differ from the arrest or booking charge once the 12th Judicial District Attorney files the case.

After booking, the person may be released on bond or personal recognizance, held for advisement, transferred to another county jail, held for another agency, or later moved into CDOC after sentencing. That is why a complete lookup should not stop at one source. Jail staff may know current local custody, Costilla Combined Court may show the case path, CDOC tracks sentenced state prisoners, BOP handles federal sentenced inmates, ICE ODLS handles immigration detention lookups, and VINELink can be used for custody or release notifications where coverage is available.

About Costilla County Jail

Costilla County is a rural San Luis Valley county along the New Mexico border. Vera classifies it as rural and lists a land area of 1,227.593 square miles. The county seat is San Luis, where the sheriff and court addresses are clustered but still separate. That local geography matters for jail users because small rural counties often publish fewer online custody tools than larger counties. In Costilla, phone, in-person, written records requests, court dockets, and state or federal locators carry more of the practical search burden.

Recent context also supports careful confirmation. The research file notes 2025 and 2026 reporting about Costilla County Sheriff's Office evidence-handling concerns, indictments, resignation, and a leadership change, while the current official sheriff page lists Joe Smith as Sheriff. Static jail pages should avoid stale assumptions about procedure and should tell readers to verify current custody, visit rules, and records routing directly with the originating office.
