What does the code "10-90 N" signify in police reporting?

The code "10-90 N" signifies "Unfounded or Unnecessary Alarm." In law enforcement communications, particularly within the NYPD, codes are used to convey specific situations succinctly. When officers encounter an alarm that is determined not to be valid or necessary upon verification, they will communicate this situation using the code "10-90 N."

This categorization is vital in police reporting because it helps to manage resources effectively. By identifying alarms that are unfounded, law enforcement can focus on more serious matters and prevent wasting time and manpower on false alarms. This is especially important in busy urban environments where timely response to genuine emergencies is crucial.

Understanding the significance of such codes assists officers and support staff in ensuring clear and efficient communication, thus enhancing overall operational effectiveness and safety within the community.
