What Is the Difference Between Jail and Prison?
Jail is a county facility run by the Sheriff that holds people before trial and people serving misdemeanor sentences or felony jail terms of up to one year.
Quick answer
Jail is a county facility run by the Sheriff that holds people before trial and people serving misdemeanor sentences or felony jail terms of up to one year. Prison is the state system for people sentenced to more than a year on a felony. Bail bonds exist only at the jail stage.
What county jails do in Arizona
A jail is run by the county sheriff. In Maricopa County that is the Sheriff's Office, which operates the 4th Avenue Jail downtown for intake and initial appearances, and the Durango complex in west Phoenix: Lower Buckeye, Estrella for women, Towers, Watkins, and the Intake, Transfer and Release facility. Valley cities also run short-term holding facilities for their own arrests.
Jails hold two groups. The first is people waiting for their case to resolve who have not been released on own recognizance or bond. The second is people serving sentences: misdemeanor jail terms and felony jail terms of up to one year. A person can be in the same building for a weekend DUI sentence or for a pretrial murder hold, which is why jail populations change daily.
What state prison is for
Prison is the state system, run by the Arizona Department of Corrections, Rehabilitation and Reentry. A person goes there after a felony conviction when the sentence is more than one year. Nobody is in prison waiting for trial; by the time someone arrives, the case is over and the sentence has been imposed.
That distinction drives everything else. A prison sentence is served, reduced only by whatever release credits the law allows, and ends with release or community supervision. There is no bail from prison because there is no appearance left to guarantee. Families sometimes call asking to bond a relative out of state prison; the honest answer is that no agent can, and anyone who offers is not describing a real process. Federal prison is a separate system with its own rules, and we handle Arizona state and county cases only.
Why bail applies to jail and not prison
Bail is a guarantee of appearance, not a payment of the sentence. Under A.R.S. 13-3967 the initial appearance judge sets release conditions so a person who has not been convicted can wait for trial at home. A surety bond from a licensed agent satisfies a secured bond for a premium of typically 10% under rates filed with DIFI, and the bond stays in force until the case ends and the court exonerates it.
Once there is a conviction and sentence, there is nothing left for a bond to secure. A person sentenced to jail time serves it in the county facility; a person sentenced to prison is transported to the state. The only way back to the bail stage is a new case, which gets its own initial appearance. Our how bail bonds work page explains the jail-stage process from first call to release.
Why the difference matters to the family
When someone calls and says a relative is 'in prison,' the first thing an agent checks is whether they mean the 4th Avenue Jail. If the person was arrested within the last day or two, they are in jail, bail will be set at the initial appearance within 24 hours, and a bond can be posted. If the person has already been sentenced, the question is about release credits and dates, which an attorney or the facility can answer.
For someone in county jail waiting on a case, the MCSO inmate search shows charges, holds and the bond amount. Releases from 4th Avenue after a bond posts usually take two to eight hours; releases from the Durango complex take longer. The jail information line is (602) 876-0322.
