Locating an Inmate at the 4th Ave Facility

Step-by-Step Inmate Search Procedure
- Access the official Maricopa County Sheriff's Office Inmate Information portal through a secure browser.
- Enter the individual's legal first and last name, or their unique Maricopa County Sheriff's Office booking number if known.
- Review the search results list, which typically displays booking photos, date of birth, booking date, and current housing location.
