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.
