County lookup

Search the name on the paperwork.

Probation, parole, or federal?

Follow the name on the paperwork.

These are separate systems. Use the agency written on the order or release instructions.

County probation directory

Choose the county named on your paperwork.

Each county runs its own department. Branches appear only when an official county page clearly ties the office name, address, and phone together. Directory order is never influenced by advertising.

Before you leave

Confirm three things by phone.

  1. 01
    The assigned office

    A county may have several field or reporting locations.

  2. 02
    The reporting time

    Hours and appointment rules can change before a website does.

  3. 03
    What to bring

    Keep the court order, release papers, identification, and officer name together.

How this directory is maintained

Official county pages first. Unclear records stay out.

Jail411 checks county probation department pages directly. A raw page crawl can mix probation offices with juvenile halls, camps, courtrooms, or unrelated county departments; those records are excluded unless the county identifies them as a public probation contact.

Information was reviewed August 17, 2026. Offices can move or change phone numbers sooner, so confirm time-sensitive instructions with the responsible county.
