San Mateo County operates 2 jail facilities. San Mateo County Correctional Facility (SMCCF) at 150 Middlefield Rd, Redwood City, CA 94063 ((650) 312-5100), Primary facility for all San Mateo County arrests from all 20 cities in the county. Maple Street Correctional Center at 1565 Maple St, Redwood City, CA 94063 ((650) 363-4300), Minimum security sentenced inmates and work programs, adjacent to SMCCF campus. CityWide posts bail at all San Mateo County facilities 24 hours a day.

Several reasons an inmate may not appear in search results: (1) The arrest was recent, allow 2–4 hours for booking to complete and records to update. (2) The person may still be at a city police holding cell awaiting county transfer. (3) Try searching last name only, a spelling variation may cause missed results. (4) For phone-only counties or very recent arrests, calling CityWide at 1-833-385-5245 is the fastest way to verify status directly with the facility.

The San Mateo County inmate locator displays: booking number (needed for mail and bail paperwork), 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. The bail amount is the key figure. CityWide charges exactly 10% of that to post a bail bond.

Release from San Mateo County typically takes 3–5 hours after bail is posted. Weekday daytime hours are fastest. Nights, weekends, and holidays can add 1–3 hours due to reduced jail processing staff.
