How to locate an inmate in Natrona County
After an arrest anywhere in Natrona County, whether in Casper, Mills, Evansville or on the highway by Wyoming Highway Patrol, the person is taken to Natrona County Detention Center, operated by the Natrona County Sheriff's Office. Booking takes one to three hours. Once complete, custody information, charges, and the bond set by the court are available.
Three ways to find someone
- Let us do it. Use the form above or call (307) 439-0555. We check the jail for you at no cost and call back with charges and bond.
- Call the detention center. (307) 235-9521 can confirm custody and bond type, but the call is not confidential.
- Visit in person. The lobby at 1100 Bruce Ln, Casper, WY 82601 can confirm custody during business hours.
What we'll tell you
- Whether the person is in custody and their booking status
- The charges and whether they're misdemeanor (Circuit Court) or felony (District Court)
- The bond amount and type: cash or surety, cash only, or personal recognizance
- Any holds from other counties or agencies
- Your options and an exact bail bond quote
If the bond type is cash or surety, we can post it right away. If it's cash only, call us anyway: we'll explain your options, including asking the court to modify the bond at the next hearing.

How long after an arrest does someone show up in the system?
