Police Eleven Codes

In addition to police ten codes, some law enforcement officers, police departments, and security forces create alternative coding systems to make their particular form of radio communication unique and private.

While most agencies use 10 codes, some departments use police 11 codes to facilitate radio communication among officers and dispatchers. As with any coding system, these form a “language” unique to a particular department or unit.

The use of these codes is not as common as police ten codes and are only used in certain areas.

List of Eleven Codes Used by Law Enforcement Officers

Following is a sample list of the most commonly used police 11 codes used by cops in the United States, primarily during radio communications and intra-departmental communication. The codes or signals are written with the number eleven, then a dash, and then another number.

When the codes are spoken verbally, they are pronounced simply as eleven, and then the appropriate number. For, example, an officer might say, “I have an eleven twenty-six and I need an eleven eighty-five. This translates to, “I have a disabled vehicle and need a tow truck.”

The codes may also be used by fire departments, EMT’s and other emergency responders:

11-6 = The illegal discharge of a firearm
11-7 = Prowler
11-8 = Person Down
11-10 = Take a police report / conduct an investigation
11-12 = Injured animal
11-13 = Dead animal
11-14 = Dog bite victim
11-15 = Ball game in street
11-24 = Abandoned vehicle
11-25 = Traffic hazard
11-26 = Disabled vehicle
11-27 = Driver’s license check, please rush
11-28 = Vehicle registration check, please rush
11-29 = Person is clear, no warrants
11-30 = Missing person
11-31 = Need help (Officer needs assistance)
11-41 = Ambulance needed
11-44 = Fatality / Death
11-45 = Suicide / attempted suicide
11-48 = Transport

Why are Police 11 Codes important to private investigators?

Private investigators may need to understand or decode police 11 codes during the course of certain investigation cases. For example, an investigator may be hired in a civil case to investigate police behavior in a particular arrest. In this example, the police may have used 11 codes to communicate before, during, or after the arrest. Having knowledge of these signals may be helpful in your investigative efforts.

  1. Chicago, is one of few if not the only PD that uses basic language over the radio. They do use codes but, if you listen to them. 95% of radio traffic is everyday talk. Which is….I think best over all, except in bad reception/signal situations. But thought that bit of info would be somewhat helpfull. Anyways…* Cutter408… I’m 10-7…out ∞Insert RogerBeep here∞ lol

    • Some of the codes could be considered standard across all police departments, while others vary. Some departments use the universal list and add a few unique codes of their own. In some cases, we’ve seen departments that create a completely unique list of codes to serve their own purposes.
