Police Codes for Crimes

Most individuals, at least once in their lifetime, have been intrigued by police codes. Over the years, different sets of police codes - Ten-codes or scanner codes – have been utilized by the American police. These codes are signals which were often used by government agencies and law enforcement agencies while communicating through a two-way voice radio, as numbered or numeric code words for frequently used messages.
The first set of codes, police 10 codes, originated in the United States Law Enforcement Community and was first published by the Association of Public-Safety Community.  The significance of these codes was to provide certain secrecy during communication and to reduce the amount of speech through the police radio.

These codes, however, were not a standardized system and varied from agency to agency, and could cause serious misunderstandings, leading to serious consequences. In 2005, the United States Federal Emergency Management Agency (FEMA) discouraged the use of these codes, due to the varied understanding of the codes.
New sets of codes are now being used in order to have a unique set of codes. The California Highway Patrol, which uses “eleven-codes” and the Port Authority Police uses “eight-codes”.
