Alameda County
Inmate Search

Use the Alameda County Sheriff inmate locator above, or call CityWide at 1-833-385-5245 for an immediate lookup without navigating county websites. Search requires a full legal name and date of birth for best results. If no results appear within 8 hours of arrest, the person may still be in a city holding cell pending transfer to county, calling is faster than refreshing the search.

Alameda County operates 2 jail facilities. Santa Rita Jail at 5325 Broder Blvd, Dublin, CA 94568 ((925) 551-6500), Primary county facility, handles all Alameda County Sheriff bookings and overflow from city jails. Glenn E. Dyer Detention Facility at 550 6th St, Oakland, CA 94607 ((510) 268-7777), Downtown Oakland facility; primarily holds male pre-trial detainees from OPD arrests. CityWide can confirm which facility currently holds your person.

Several reasons a person may not appear in results: (1) They were arrested less than 4–8 hours ago and processing is not complete. (2) They are still in a city police holding cell before county transfer. (3) They were booked under a slightly different name, try last name only. (4) They may be held in a neighboring county. Call CityWide at 1-833-385-5245 and we verify status directly with the facility in minutes regardless of system lag.

The Alameda County inmate locator displays: booking number (keep this, you need it for mail, calls, and bail), current facility and housing unit, booking date, arresting agency, charges by California Penal Code section, bail amount set by the court, arraignment or next court date, and projected release date for sentenced inmates. Bail amount is the most important field, 10% of that number is what you pay CityWide to secure release.

Release from Alameda County after bail typically takes 4–8 hours. Weekday morning and afternoon releases are fastest. Nights, weekends, and holidays can add 1–2 hours due to reduced jail staffing. CityWide posts bail at all Alameda County facilities 24 hours a day and monitors the processing queue until the person walks out.

Alameda County bail schedule: DUI at $5,000, domestic violence at $25,000, assault at $25,000–$50,000, burglary at $30,000, most felonies $25,000–$250,000. California law sets bail bond premiums at exactly 10% of the full bail amount, this rate is the same for all bail agents in all 58 counties. CityWide offers payment plans for qualified co-signers. Call 1-833-385-5245 for an exact quote based on the charges and booking record.

Santa Rita Jail visits are video-based and appointment-required through the Alameda County Sheriff portal. Glenn E. Dyer allows in-person visits on a limited schedule. Both facilities require prior registration. Contact Santa Rita at (925) 551-6500 or Glenn Dyer at (510) 268-7777 for current visiting hours. All visitors must present government-issued photo ID.

Alameda County has two main jail facilities. Oakland arrests by OPD typically go to Glenn Dyer Detention Facility downtown. Arrests by the Alameda County Sheriff or agencies outside Oakland usually go to Santa Rita Jail in Dublin. The two-facility system means verifying which one holds your person is the critical first step. CityWide confirms location instantly at 1-833-385-5245.

Alameda County's inmate search uses an image captcha. Type the letters or numbers shown in the distorted image to proceed. Search by last name and first name, or by booking number. Glenn Dyer and Santa Rita are on the same system. If no results appear within 8 hours of arrest, the person may still be at a city holding facility. Oakland, Berkeley, Hayward, and Fremont all have short-term holding before county transfer.
