FAQs

Why Searching for an Inmate in San Mateo County Can Be Complicated?

Searching for an inmate in San Mateo County can sometimes be a complex process for a number of reasons, even with the official online tools available. Here are some of the most common complications:

  • Delays in Booking: When a person is arrested, they are not immediately entered into the online database. They must first go through a detailed booking process at one of the county’s facilities, which includes fingerprinting, photographs, and data entry. This can take several hours, especially during busy periods, leading to a delay between the arrest and when the information becomes publicly accessible.

  • Inaccurate Search Information: The online locator requires a precise search. If you misspell the person’s name, use a nickname, or have a hyphenated name that is not entered correctly, the system may not return any results. This is one of the most frequent reasons for a failed search.

  • Inmate Transfers: While the official tool is generally updated, inmates can be transferred between the two main county facilities—the Maguire Correctional Facility and the Maple Street Correctional Center or moved to a hospital for medical reasons. If you don’t use the online locator and rely on old information, you may be looking for them in the wrong place.

How long does locating an inmate in San Mateo County Jail take?

In most cases, if you search a few hours after an arrest, you should be able to find the person you’re looking for. However, if you’re unable to find them, it’s always a good idea to wait a bit longer, as the booking process might be delayed. You can also try calling the jail directly for the most up-to-the-minute information.

Can you help if an inmate has been moved to a different facility?

Yes, the San Mateo County Sheriff’s Office’s official “Inmate Locator” is the best tool for this. The system is designed to provide real-time information on an inmate’s current location within the county’s custody.

Here’s how it works:

  • Centralized Database: The online locator pulls information directly from the jail’s central database. This means if an inmate is moved from one facility (like the Maguire Correctional Facility) to another (like the Maple Street Correctional Center), the search results will be updated to show the new location.

  • Searching by Name or Booking Number: When you search by an inmate’s name or their booking number, the system will give you their most current housing location, along with other essential details. This makes it the most reliable way to track an inmate’s whereabouts within San Mateo County.

It’s important to note that this tool only tracks inmates within the San Mateo County Sheriff’s jurisdiction. If an individual is transferred to a state or federal prison, they will no longer appear in the county’s system. In such cases, you would need to use a separate state or federal inmate locator.

Do you work directly with the San Mateo County Sheriff’s Department?

For the most accurate and up-to-date information on inmates, services, or any other official business, you should always refer to the direct resources provided by the San Mateo County Sheriff’s Office. This includes their official website and their designated phone numbers. Relying on these official sources ensures you receive correct and timely information straight from the source.
