If you’ve ever listened to police scanners or watched crime shows, you might have heard mysterious codes like “Code 10” or “Signal 30.” These are police codes—short, efficient radio codes used by law enforcement to communicate quickly. In the United Kingdom, police codes are widely used by officers to describe incidents, locations, or actions without broadcasting sensitive information over open radio frequencies.

In this guide, we will help you understand UK police codes, how they are used, what they mean, and how PoliceCode makes it easier for everyone to check them free of charge. You’ll also learn how to start using PoliceCode’s fast, simple lookup tool online without any login or registration.

What Are Police Codes?

Police codes are a series of numbers or letters used by police officers and emergency services to communicate efficiently. Instead of describing a situation in full detail, officers can use short codes to save time and maintain confidentiality.

Why Use Police Codes?

• Speed: Helps officers convey critical information quickly

• Clarity: Removes ambiguity by standardizing phrases

• Discretion: Keeps information from being easily understood by the public

• Coordination: Ensures consistent language across multiple departments
  
  

In the UK, police codes can vary slightly between constabularies, but many follow a standard national code system for clarity and operational efficiency.

Commonly Used Police Codes in the United Kingdom

Let’s explore a comprehensive list of police codes that are frequently used by law enforcement agencies in the UK. The list includes incident types, officer statuses, and emergency response codes.

1. 10 Codes (Ten Codes)

While the 10-code system is more common in the United States, some UK services have adapted it informally. Here are a few examples:

• 10-1 – Unable to copy, change location

• 10-4 – Acknowledged

• 10-7 – Out of service

• 10-8 – In service

• 10-20 – Location

• 10-33 – Emergency, all units stand by
  
  

Note: These may vary or not be officially adopted in some UK departments, but are widely recognized in radio communication.

2. Status Codes

These are used to inform dispatchers or fellow officers about the status or activity of a unit.

• Code Zero – Officer requires urgent assistance

• Code One – Proceed immediately (response time under 15 minutes)

• Code Two – Proceed without emergency equipment

• Code Three – Proceed using blue lights and sirens

• Code Four – No further assistance needed
  
  

3. NATO Phonetic Alphabet

UK police forces use the NATO phonetic alphabet for clear radio communication of letters or vehicle registrations.

• A – Alpha

• B – Bravo

• C – Charlie

• D – Delta

• … to Z – Zulu
  
  

This is essential when officers are describing names, codes, or vehicle plates over the radio to avoid miscommunication.

4. Incident Codes (Used in Police Reports and Dispatch)

• IC1 – White – North European

• IC2 – White – South European

• IC3 – Black

• IC4 – Asian (Indian, Pakistani, Bangladeshi)

• IC5 – Chinese, Japanese, or Southeast Asian

• IC6 – Arabic or North African

• IC9 – Unknown
  
  

These codes refer to ethnic appearance classifications used by officers during incident reporting.

5. Call Signs and Response Grades

Police in the UK also use call signs and response grades to classify urgency:

• Grade 1 – Emergency response required

• Grade 2 – Priority, but not an emergency

• Grade 3 – Scheduled response

• Grade 4 – Telephone or online resolution

How Police Codes Are Used in Daily Situations

Let’s take a few real-life examples to show you how codes are used:

Example 1: Pursuit Situation

Officer 21 to Control, in pursuit of a vehicle failing to stop, request Code Zero backup. IC3 male driver. Vehicle: Golf GTI, registration Delta-Bravo-20-Charlie-Romeo-Kilo.

This quick message tells control:

• An emergency backup is needed (Code Zero)

• The suspect is a Black male (IC3)

• Vehicle registration is clear using the NATO alphabet
  
  

Example 2: Stop and Search

Control to Bravo Unit 14, stop and search report filed. IC2 subject, complying. No weapons found. Status Code Four.

Translation:

• The suspect is a white South European male (IC2)

• No danger, no further assistance required (Code Four)
