Clear information.
Clear boundaries.

Jail411 lists the public agencies that make arrests so families can find the right door. We are not a government agency, a police department or a live custody-records service.

Is the sheriff's office the same as the jail?

Often the sheriff runs the county jail, but the jail is a separate facility with its own address, phone and rules. Open the jail page for booking, visiting, mail and money details.

How do I find out which department made the arrest?

Ask the person, check any paperwork or citation, or call the sheriff's non-emergency line. City arrests belong to that city's police; unincorporated areas and county roads usually belong to the sheriff; freeways usually belong to the state patrol.

Can these agencies tell me if someone is in custody?

The jail can. The arresting agency may confirm an arrest but does not hold the person. Call the jail's booking or information line first.

What if a listing needs correcting?

Send us the page and the detail that needs attention. Include the agency's official page when you have it. Do not send private booking documents or other sensitive personal information.
