Union City Police Department Holding Facility Lookup

Union City Police Department Holding Facility Overview

The RAJ/BSCC July 2024 table lists Union City Police Department as type THJ, status open, with 0 rated capacity. The Facility Map describes it as short-term holding and processing and specifically warns that it should be treated as a processing or holding location rather than a jail comparable to Santa Rita. That zero-capacity figure is the main accuracy point for Union City.

The Facility Map includes 34009 Alvarado-Niles Rd, Union City, CA 94587, with a note to verify through official Union City Police materials. No official facility phone number was captured from an opened source, so none is invented. RAJ indicates Union City PD can book at Fremont Police Department or Santa Rita Jail. That routing explains why someone arrested by Union City police may appear in a different facility record path.

For county jail custody, use the Alameda County Sheriff's Office Inmate Locator and Santa Rita Jail. For formal charges, use Alameda Superior Court. For state prison, federal prison, or immigration custody, use CDCR CIRIS, BOP, or ICE ODLS respectively.

Union City Holding Capacity and Population

The sourced RAJ/BSCC capacity is 0. That does not mean Union City police cannot arrest or process someone; it means the facility should not be described as having a public jail population or normal long-term detention capacity. No current daily population count, visit schedule, roster count, or annual booking count was captured for this facility.

A zero-capacity listing is also a warning against copying Santa Rita Jail statistics onto a local police page. Alameda County's 2025 jail population snapshot belongs to Santa Rita Jail. Union City is part of the booking and routing map, so the useful public question is where the person went after local processing.

How to Look Up a Union City Arrest

No separate Union City public jail roster was captured. If the arrest is new, the useful question is whether the person was released, taken to Fremont Police Department, transferred to Santa Rita Jail, or routed to court. Search the ACSO Inmate Locator for current Santa Rita custody. Use the Alameda Superior Court criminal portal for charges, hearings, and warrants after a case is filed.

1. Use official Union City Police channels for immediate post-arrest processing questions.
2. Check whether the person was booked at Fremont Police Department or Santa Rita Jail.
3. Search ACSO by PFN, first and last name, DOB, sex, phonetic search, or last-24-hours bookings.
4. Use court records after formal charges or a hearing appear.

Union City Police Department Holding Facility Address and Contact

The available research provides a facility-map address but no verified phone number from an opened official source. Confirm the address and any public lobby routing through official Union City Police materials before travel. County custody and release questions belong with Santa Rita Jail after transfer.

The research's safer fallback is the countywide sequence. Santa Rita Jail handles the main Alameda County jail custody line. ACSO public records requests handle sheriff-held booking records not shown online. Alameda Superior Court handles filed charges, hearings, and warrants. Those channels are more reliable than assuming Union City has a separate public jail desk.

Visiting Someone at Union City Police Department Holding Facility

The research did not capture public visiting hours, and the zero-capacity listing makes normal social visitation unlikely as a public workflow. Do not publish Santa Rita Jail's appointment rules as if they apply to Union City. If the person is transferred to Santa Rita, confirm custody and then use Santa Rita's current visiting schedule and identification rules.

Mail, Phone, and Money for Union City Holding

No Union City-specific public mail, commissary, deposit, video, or phone vendor details were captured. A zero-capacity processing location should not be given county jail service instructions. If the person is in Santa Rita Jail, use Santa Rita Jail's confirmed mail, video, phone, and money rules at that point.

Booking and Intake for Union City Arrests

Union City's records path can move through more than one location. RAJ says Union City PD can book at Fremont Police Department or Santa Rita Jail. The public may therefore need to check immediate local police status, Fremont-related processing, ACSO county custody, and court filing status. A missing Union City jail roster is not a records dead end; it means the search belongs in the next custody or court system.

The zero-capacity listing makes this especially important. It points to processing and transfer, not a facility where a public inmate population is held for days. A person may be released after local action, moved to Fremont for booking support, taken to Santa Rita for county jail custody, or linked to a court case after prosecutor review. Each path creates different records.

About Union City Police Department Holding Facility

Union City carries a strict caveat: it is listed, open, and relevant to booking routes, but RAJ/BSCC assigns zero rated capacity. Long-term jail language and unsupported phone, roster, visiting, mail, or money claims are avoided. Santa Rita Jail remains the primary public jail lookup for Alameda County custody after transfer.

The Facility Map also shows why Union City cannot be handled like Santa Rita Jail. Santa Rita has a sheriff locator, visiting rules, mail-routing notices, population statistics, and a public phone line. Union City's captured source detail is mainly facility classification and routing. The content therefore stays focused on how to move from a Union City arrest question to the correct official system.
