Understanding how law enforcement communicates can give you a deeper appreciation for how safety is managed across cities and provinces. In Canada, police officers use specific codes and signals to communicate efficiently, especially during high-pressure or emergency. These are known as police codes—a language of numbers and signals that help officers transmit complex messages quickly and clearly.
Whether you’re a student, journalist, researcher, or simply a curious citizen, you can now check the full police code list of Canada for free using PoliceCode—a platform that makes these codes accessible without requiring registration.
What Are Police Codes?
Police codes are combinations of numbers and words used by officers to communicate over radio systems. These codes are essential for:
Shortening response time
Conveying messages clearly during emergencies
Maintaining operational security
Avoiding miscommunication over noisy radio channels
Rather than explaining an entire scenario over the radio, an officer might say “10-33,” which quickly informs other officers that an emergency is in progress and urgent assistance is needed.
Quick Example:
Instead of saying:
“There’s a robbery in progress at the store on 4th Street. Please send backup immediately.”
An officer might say:
“10-31 at 4th Street. Code 3.”
These brief yet powerful phrases save valuable time and ensure swift and accurate communication. You can explore a vast list of such codes using PoliceCode, completely free.
Why Do Canadian Police Use Codes?
Police officers across Canada deal with unpredictable, dangerous, and high-pressure situations. Whether managing a car chase, responding to a domestic disturbance, or dealing with suspicious activity, there is little time for long conversations.
Here’s why police codes are so important:
Time-Saving: A simple number can replace entire phrases.
Clarity: Reduces misunderstanding over noisy radio channels.
Discretion: Keeps sensitive information from public scanners.
Uniformity: Ensures officers across departments understand one another.
Security: Prevents criminals or civilians from easily understanding operations.
While modern policing is shifting toward more plain language communication, codes are still widely used across most jurisdictions in Canada.
Types of Police Codes in Canada
Police codes in Canada are not universally standardized, meaning some provinces and departments may use different codes or apply them differently. However, most follow similar systems, such as 10-Codes, Numeric Codes, and Status Codes. Let’s break these down.
1. 10-Codes (Ten Signals)
These are perhaps the most familiar set of codes. Each code begins with the number “10” followed by another number indicating the specific message.
Some commonly used 10-codes in Canada include:
10-1 – Signal weak / Unable to copy
10-4 – Acknowledgement / Message received
10-7 – Out of service
10-8 – In service / En route
10-20 – What is your location?
10-31 – Crime in progress
10-33 – Emergency / Need urgent help
10-36 – Correct time
10-42 – End of shift
PoliceCode provides a full list of 10-codes and their meanings, which you can access instantly.
2. Numeric Emergency Codes (Code 1 to Code 6 and beyond)
These codes indicate response priority levels and are crucial during dispatch or in-progress calls.
Code 1 – Routine call, no lights or sirens
Code 2 – Urgent, but non-emergency; no sirens
Code 3 – Emergency with lights and sirens
Code 4 – No further assistance needed; situation under control
Code 5 – Stakeout in progress
Code 6 – Proceed with caution
These codes are often used in dispatch to inform units how urgently they must respond. Officers responding under Code 3, for example, are authorized to use emergency lights and sirens, enabling them to navigate through traffic swiftly.
3. Status and Action Codes
These codes refer to officer activities, case statuses, or ongoing operations.
Code 7 – Meal break
Code 10 – Bomb threat
Code 12 – Officer needs assistance
Code 21 – Warrant service
Code 30 – Homicide investigation
Code 50 – Hostage situation
These codes can be province-specific and are used in real-time communication to relay important situational updates without revealing sensitive details on open radio channels.

Provincial Differences in Police Codes
Although many codes are shared across jurisdictions, some variations exist by province or department.
Ontario
Many departments are shifting toward plain language.
Still use standard 10-codes in patrol operations.
British Columbia (RCMP Districts)
RCMP officers still rely heavily on numeric and 10-codes.
Use Code 3, 5, 6, and 12 regularly during interventions.
Quebec
The Sûreté du Québec and local police services use a mix of numeric codes and French terms.
French-speaking officers use adapted versions of codes to suit linguistic needs.
Alberta
RCMP divisions use consistent code structures, often identical to those in BC.
Some rural areas rely on status codes specific to agricultural or border patrol.
Using PoliceCode, you can access these regional variations to understand how the same code might mean something slightly different depending on where you are in Canada.
Police Radio Communication Protocol
Police officers must follow strict radio protocol. Here’s how a typical communication might sound:
“Dispatch, Unit 402, Code 3, responding to 10-31, corner of King and Queen.”
Translated, that means:
“This is patrol unit 402, responding urgently (with lights/sirens) to a robbery in progress at King and Queen Streets.”
This brevity keeps communication fast and effective. It also minimizes radio usage time, keeping channels open for others.
The Evolution of Police Codes in Canada
Though police codes have existed since the early 20th century, their usage has evolved:
1930s–1950s: Early versions of 10-codes were developed in the United States and adopted in Canada.
1960s–1990s: Widespread adoption across provincial and federal departments.
2000s–Present: Gradual shift toward plain language, especially during multi-agency responses or public events.
Still, many police departments rely heavily on coded language during internal operations.
Why Civilians Need to Understand Police Codes
Police codes are not just for law enforcement. Citizens, students, journalists, and public safety workers can benefit from learning them. Here’s why:
1. Situational Awareness
Knowing what “Code 3” or “10-33” means can help you understand what’s happening in your neighborhood if you hear a police scanner.
2. Career Preparation
If you’re interested in law enforcement, private security, or emergency services, familiarizing yourself with police codes gives you a professional edge.
3. Media and Journalism
Reporters covering crime or public safety stories often encounter these codes in press briefings or scanner feeds.
4. Academic Use
Law students and criminology researchers often study communication systems in law enforcement as part of broader criminal justice studies.
Can You Listen to Police Radios in Canada?
In some provinces, police scanner traffic is encrypted, especially in larger cities. However, rural areas or small departments may still use unencrypted frequencies.
Even when you can’t listen in, understanding codes still helps when reading incident reports, news articles, or police announcements. And thanks to PoliceCode, you can stay up-to-date with the meanings behind those codes.
