Confirm Where the Person Is Before You Call
The Denver Sheriff Department publishes a free online inmate search that tells you which facility holds a person in its custody.3City and County of Denver. Find and Visit Someone In Our Care Checking there first saves you from calling both numbers. Search by name. If nothing comes back, the person may have been released, transferred to a state facility, or booked under a name variation.
What to Have Ready When You Call
Jail staff take a lot of calls, and the right details on hand move things along. At minimum, know the person’s full legal name, including middle name or suffix, and their date of birth. Many people share names in a system this size, so the date of birth is often how a clerk narrows the record.
If you have the person’s City Department (CD) number or booking number, lead with that. Those are unique identifiers and pull the exact record immediately. Without one, staff may not be able to share housing location or court-date specifics.
Posting Bond
You can post bond in person at the Van Cise-Simonet Detention Center 20 hours a day, seven days a week, including holidays. Denver County Court also runs an online bonding platform that you or a bail bond agent can use remotely.4Denver County Court. Bonding and Warrants Division For questions about a specific bond amount or conditions, call the bonding office at 720-337-0062.

Visiting in Person or by Video
Denver offers remote video, lobby video, and in-person visits. Both video types at either facility have to be scheduled through Securus at least 24 hours ahead.6City and County of Denver. Family and Friends Guide Remote visits work from a computer, tablet, or phone through the Securus app. If online signup is giving you trouble, the kiosks in the facility lobbies are a workable backup.
In-person visits are available only at the Denver County Jail on Smith Road, not at the downtown detention center. Each visit runs up to 30 minutes, with a cap of two visits per week and one per day. For current hours and eligibility, call the County Jail at 720-913-3600.
Sending Mail

Denver Sheriff Department

The processing center scans mail and uploads it to a password-protected account the person reads on a tablet or housing-unit kiosk.9Denver Sheriff Department. Inmate Mail Policy Prohibited items include credit card and bank account numbers, Social Security numbers, government documents, gang-related material, sexually explicit content, and anything sent through a third-party mailing service.
