- About the Jail
- The Isanti County Jail and work release operate under the Isanti County Sheriff's Office. The jail is a separate government function from the court: the jail holds people in custody, while the court decides release conditions.
- Checking Inmate Custody
- The county publishes an official In Custody page that embeds the Sheriff's custody roster. Use that government-operated page directly — GPS does not operate it, and its information can change. Call Jail Master Control at 763-689-2397 to confirm.
- Posting Bail at the Jail
- Before traveling, confirm current custody, whether bail has been set, any court-ordered release conditions, which payment methods are authorized, whether an eligible surety bond is permitted, and whether any holds or restrictions apply. Call Jail Master Control at 763-689-2397.
- Release Information
- Once release is authorized, the jail must complete its own procedures. Other holds, warrants and court orders can affect timing — no one can promise immediate release or a fixed processing time.
