Now that you have your own police scanner, you find that some conversations make little to no sense, especially when they’re coming from law enforcement agencies. Things like “Code blue” and “10-7” might have you scratching your head. If you don’t understand these things, you won’t get the full use out of your device.

What are Police Scanner Codes?
The words and numbers that made it to your scanner radio (or your smartphone, if you have any of these top police scanner apps) are collectively called police scanner codes.
Number or color codes were devised to refer to particular situations encountered by the police, firemen, and the like – but in an abbreviated way.
The use of these in a call has obvious benefits, such as being direct with the circumstance at hand and giving the information a veil of secrecy, no matter how thin. Of course, there are some things they don’t want the public to hear.
Codes reduce speech on radio so available services can address the situation in the fastest time possible. However, their use has not been practical in certain instances.
Do the Codes Apply to All Radio Users?
It’s important to note that the codes used on police radio are not universal. Sometimes, the police may also use direct abbreviations like ADW for “assault with a deadly weapon” instead of code 245.
While there are standardized codes, certain states and even particular departments (such as fire or emergencies) might require some codes to be more specific to them. The purpose is to help with differentiation.
Now, if you don’t have a police scanner yet, you can check this page for options.
Private citizens also often have their own set of codes. This lack of uniformity in the whole nation led the United States Federal Emergency Management Agency (FEMA) to not recommend the use of the codes on the radio in 2005.
Why Does the Police Use Codes?
Police scanner codes, specifically those in use by law enforcement agencies, originated in the 1940s. The first set was standardized and consequently published by the Association of Public Safety Communication Officials (APCO).
Today, however, some of the codes were replaced and used with simpler terms to prevent having to refer to the set often, especially considering that the lists are usually hefty. Newer codes also placed a priority on becoming brief yet clear because older codes failed to give a short yet holistic indication of what is happening.
The codes are meant to help and address a myriad of emergencies, such as fire situations, burglaries, road accidents, medical accidents, and bomb threats. They can be numeric, or expressed by way of colors to give information.
You can learn what the law enforcement codes are for by referring to the list we have below. Here are some of the codes currently used in the United States:

Introduction
A police scanner is a radio receiver able to tune or scan frequencies. It monitors UHF and VHF hand-held mobile radio systems. It can receive messages one at a time, and send out multiple signals at the same time. A scanner device is further enhanced with the use of codes, like number or color codes. To reduce the negative effects of radio static, short codes are used. Police scanner color codes reduce sentences and phrases into two-word signals.

Code 3 Use lights and siren
Code 4 No further assistance needed
Code 5 Stakeout
Code 6 Stay out of area

Police Scanner Color Codes
Police scanner color codes have been a great help in police emergency operations for years. Also known as an efficient mode of radio communication among ten-eleven codes, police scanner color codes have saved countless lives and properties.
A robber on the run is escaping from law enforcers and jumps into a public bus. The passengers are in danger and more police back-up is needed. An officer reaches out for the radio in the police car unit and says, “We have a code blue.” Then the officer adds other details. This is how police scanner color codes are used in an actual police emergency.
What are Police Scanner Color Codes?
These are among 10-11 (ten-eleven) codes that identify radio frequency quickly. They also enable law enforcers and other relief or rescue operators to report situational updates and receive instructions. For requesting immediate help fast, like police back-up, police scanner color codes are also used. There are, to date, only three color ten-eleven codes.
What are the Three Scanner Color Codes?
- Code Blue – Bus or taxi in trouble
- Code Red – VARDA (Voice Activated Radio Dispatched Alarm) activated
- Code Purple – Gang activity
First, Code Blue. This indicates that a public vehicle, like a bus or cab, is in trouble. Like in the example above, police operatives need not say, “We have trouble here. An armed suspect boarded a bus and is endangering the passengers.” All the law enforcer has to say over the radio is, “We have a code blue.” Police scanner color codes make reporting and updating fast and easy.
Second, Code Red. It means the Varda alarm has been set off. VARDA is an acronym that means Voice Activated Radio Dispatch Alarm. It is placed or installed on an object, like a car engine or chassis. When someone moves the car unaware, an alarm is automatically set off at a nearby police station. A voice recording programmed to announce ten-eleven codes will be sent to all police car units and an officer will be dispatched to the site immediately. Police scanner color codes enables law enforcers to act fast within minutes.
Third, Code Purple. When a mob or gang in a neighborhood gets violent or threatening, and it is reported to the station, a code purple is sent to all units. Any available unit should respond at once to the scene. Or, if a lone law enforcer sees a gang activity, immediate back-up should be requested by merely saying the code and location details. Police scanner color codes and other ten-eleven codes make a potential danger easy to contain within minutes.
Police Scanner Penal Codes
When trouble strikes, fast and efficient police response is of utmost importance. Reporting the situation to police headquarters in a long-winded or rambling way will not do. Thus, practical police scanner penal codes were formulated for fast and efficient police radio communication.
For Criminal Acts
Police scanner penal codes are designed to be used during monitoring of or pursuing suspected criminal elements. When surveying acts worthy of punishment by the law, and especially when danger seems inevitable or impending, police radio communication uses police scanner penal codes. This makes radio conversations efficient and fast. Among criminal activities monitored with penal codes are homicide, kidnapping, robbery, assault, rape, and illegal possession of arms, among others.
Penal Codes Exclusive to Some Departments
Some police scanner penal codes are common to various police departments, while others are exclusive to a particular department or station. Some state law enforcers may use a different police radio communication signal from another. Similarly, some scanner codes used by police departments, fire departments, and rescue and relief teams, differ from each other. This is due to some special tasks specific to the nature of their work. Ambulances, fire trucks, tow trucks, and police car units, for instance, have different uses, though all are for emergency uses. Hence, they use different radio communication signals.
Among common codes used for penal monitoring purposes is code 217. When a pre-meditated murder is in progress and an officer needs back-up, code 217 or assault with murder attempt is the right code to use. The officer may simply say over the radio, “Code 217 at Madison Avenue. Requesting for 11-99!” This is a combination of police scanner panel codes and eleven codes, another set of emergency radio codes. A report on assault with intent to murder and request for back-up at a certain location is quickly done with a short one-line radio communication.
A 273D Police Report
Reports should be done in such a way that details are relayed accurately without divulging them to civilians who may be present in the operation or at the time of reporting. For instance, the family of a woman who is a victim of cruel wife-beating is around the police premise. If family members are not supposed to know how grave the incident is, officers may talk of the case in front of them without revealing any sensitive detail. This is possible by simply saying 273D (another common police scanner penal code) when referring to it.

Police Scanner Eleven Codes
Police scanner eleven codes were primarily designed to address the needs of the California Highway Patrol. Traffic operatives and officers from this service felt the need to expedite radio communications. So they came up with these radio communication codes. The eleven codes were closely applied alongside the ten-codes to simplify radio conversations especially during emergencies. Here are some of their uses:
For Emergencies and Others on the Road
Police scanner eleven codes are mostly about highway and road emergency situations. They range from accidents, road crimes, car chases, traffic, transportation assistance, automobile repairs, parades, and escort or convoy protection. It would be difficult for operatives to drive while reporting road updates, especially when mounted on a motorcycle. This is where scanner radio communication codes come in handy.
For Short and Simple Reports
The nature of work the California Highway Patrol group (CHPG) has, keeps it out on the main roads and highways often. These are noisy places where short and simple radio communication codes are needed. Instead of saying, “There is a vehicle collision at the corner of interstate 24 and highway 7. We need an ambulance, quick! There may be casualties!” the operative can simply say, “11-79 at i-24 and highway 7. Possible 11-44.” With such short and simple police scanner eleven codes, the dispatcher gets the whole picture. Immediate and accurate help is then dispatched.
For Calming Down a Tense Situation
Police scanner eleven codes are also used to keep sensitive information from becoming public knowledge. For instance, a bomb is sniffed by a k-9 dog inside a public bus and there are passengers on board. A CHPG operative would know that, but not the passengers. To report the emergency update, the law enforcer would use radio communication codes. Even if the people hear the updates, they won’t panic.
For Protecting Classified Information
Radio communication codes are supposed to be exclusive to law enforcement operatives. But sometimes, the signals can be intercepted by lawless elements adept at electronic technology. When this happens, police scanner eleven codes are useful. They keep vital information confidential, though communicated in the hearing of unauthorized persons. Or, reporting of sensitive update details can be shifted to a landline transmission. This is done by simply saying, “11-58.” The receiver of the code will immediately understand that radio communication codes are being intercepted. Telephone communication will have to be resorted to.
For Quick Back-Up
A highway patrolling job can be quite hazardous. One can never know what danger may be waiting out there in the byways and highways. In case an immediate back-up support is needed, a mere “11-99” radio report is all that is needed. The station will immediately dispatch reinforcement to the location.

Police Scanner Ten Codes
What are Police Scanner Ten Codes?
These codes are used to replace actual words or phrases used in radio communications. They are often used by police and fire departments. In most cases, they are used in ambulances during emergencies. Those involved in rescue operations during disasters also use them. Among popular police scanner ten codes is “10-4.” It means a radio message or signal is received loud and clear.
Why “Ten” Codes?
There are some dozens (not just ten) of police scanner ten codes generally in use today. They are all prefixed with the number ten. Hence, the term “ten” codes. “Ten” was chosen way back in 1937. It was the time when radio communication codes began to be used. This was to hasten police reporting through radio and remedy the problem of radio static. The first few seconds of transmission was blurred by static. Hence, to make sure messages were not affected by it, a preliminary code “10” was first sent immediately followed by the main code.
