The Code 37 police code meaning for the police forces is Subject/Property Wanted.

The Code 37 police code is a commonly used signal in law enforcement that alerts officers to a “Subject or Property Wanted” status. When police personnel use Code 37, it typically means there is an individual or item—often a vehicle—that is flagged in a database as being wanted in connection to a criminal investigation, warrant, or report. This could involve anything from a stolen car to a suspect being sought for questioning or arrest.

So, what is Code 37 Police Code exactly in law enforcement communication? It’s a shorthand message that helps police units quickly and clearly understand that someone—or something—has been listed as wanted, which requires immediate verification and possible action. The moment a Code 37 is triggered, dispatchers and officers coordinate to confirm details through systems like the NCIC (National Crime Information Center), local law enforcement databases, or BOLOs (Be on the Lookout alerts).

Why the Code 37 Police Code Is Essential in Modern Policing

Understanding Code 37 police code usage is crucial for effective communication and fast response in the field. Law enforcement agencies use a system of numbered codes to simplify radio chatter, reduce misunderstandings, and ensure quick information exchange during high-pressure situations. A Code 37 is often associated with vehicle stops or when running plates through a database—if the system pings a match, it’s flagged with Code 37: Subject/Property Wanted.

For example, an officer might pull over a vehicle and request a license plate check. If the dispatcher replies with a Code 37, it means the vehicle has been reported stolen or is otherwise flagged, and the officer should proceed with caution and follow specific protocol. Similarly, if an officer encounters an individual during a stop and runs their ID, a Code 37 hit would indicate an active warrant or investigative interest.

Over time, these numeric codes became an essential part of police procedure, streamlining everything from emergency response to routine checks.

While the exact codes may vary by state or jurisdiction, Code 37 remains widely recognized across many law enforcement agencies in the United States.

Interestingly, the roots of police radio codes go back even further. As early as 1935, APCO proposed brevity codes adapted from the U.S. Navy’s Morse Code symbols.
