What Does Police Code 27 Mean?

Written by Neil Norris

Understanding police codes can feel like trying to decode a secret language. “Code 27” is one such term you’ve probably encountered in movies, radio chatter, or true crime TV shows. Yet, despite its frequent appearance, this code doesn’t carry a universal meaning across all law enforcement agencies. If you’re curious about what police code 27 means, how and where it’s used, and why codes vary, you’re in the right place.

This blog will break down the basics of police radio codes, reveal the most common meanings for code 27, explore regional variations, and explain why police shorthand still matters. Whether you’re a true crime enthusiast, a writer looking for authenticity, or simply want to understand your local scanner, this guide has you covered.

Decoding the Basics of Police Radio Codes

Police radio codes, sometimes called “ten-codes” or “signals,” were first developed in the 1930s and 1940s. The goal was efficiency and clarity on crowded airwaves, especially as police departments adopted new radio technology. Instead of long explanations, officers could use brief codes to convey critical information about incidents, status, and emergencies.

Common Police Code Types

Police codes generally fall into three categories:

  • Ten-Codes (e.g., 10-4, 10-20): Used to describe situations, requests, and statuses. “10-4” means “acknowledged” or “message received.”
  • Signal Codes (e.g., Signal 27): Often unique to a city, county, or department, these indicate specific events or statuses.
  • Numeric Codes (e.g., Code 27): Standalone numbers that each represent a type of crime, event, or officer request.

The result? A system designed to streamline communication while preserving privacy and sometimes even officer safety.

The Meaning of Police Code 27

No National Standard

Here’s the tricky part with police code 27: there is no nationwide, standardized definition. Code 27 can mean several different things depending on the agency, state, or even the era. This is because law enforcement agencies often customize their code lists to suit local needs and priorities.

Common Usages of Code 27

Despite variations, here are the most widely reported and documented uses for police code 27:

1. Warrant or Wanted Person Check

One of the most common meanings, especially in jurisdictions across the United States, is:

Code 27 = Check for wants and warrants on a subject/person (often using the individual’s ID or license data).

Example radio call:

“Dispatch, 1-Adam-12. Running a Code 27 on John Smith, California license 123ABC.”

(This means the officer is requesting dispatch to check if “John Smith” is wanted for any outstanding warrants.)

2. Arrest Warrant Hit

Some departments use code 27 specifically to confirm that an individual has an active warrant.

  • Dispatcher to officer: “You have a Code 27 hit on your subject.” (Translation: The person is wanted, proceed with caution.)

3. Other Meanings (Less Common)

  • Ambulance or Medical Emergency: Some older or region-specific code books use 27 to indicate a medical call.
  • Special Reports or Paperwork Needed: Rarely, it can mean an officer needs to file a particular report.

Always refer to your local agency’s codebook or website, as variations persist.

Why Police Codes Vary Across Regions

Evolution of Communication

Over time, police forces shifted from strict codes to plainer language, prompted in part by federal guidelines after major emergencies (notably post-9/11). Still, many codes remain deeply rooted in tradition or offer vital brevity in fast-moving, high-pressure situations.

Examples of Regional Differences

  • California Law Enforcement: Many agencies use “Code 27” for warrant checks or wanted person checks.
  • Florida: “Signal 27” is sometimes a request for a backup unit.
  • Texas: “27” may appear with other signals or be replaced entirely with plain language.

This lack of uniformity is why context matters when interpreting police scanner traffic or media reports.

How to Find the Meaning for Your Area

If you’re listening to a scanner or reading about a police incident and hear “Code 27,” the only way to be sure of its meaning is to:

  • Consult Local Law Enforcement Resources: Many police websites publish their codes online.
  • Use Community Forums: Dedicated radio and scanner hobbyist communities often maintain regional code lists.
  • Ask Directly: Local law enforcement public affairs officers can often answer non-sensitive code questions.

Are Police Codes Still Relevant Today?

Despite calls for plain language in emergencies, codes like 27 are still relevant in everyday policing for several reasons:

  • Brevity: Saying “27 on license plate ABC123” is faster and clearer than a long explanation.
  • Privacy and Security: Certain information isn’t intended for the public, suspects, or media listening in.
  • Tradition: Many officers and dispatchers are trained in radio code from early in their careers.

However, for major incidents, agencies increasingly use plain English to avoid confusion when multiple units (sometimes from different regions) respond.

Police Code 27 in Popular Culture

From classic TV like “Adam-12” to more recent shows like “Cops,” police code references can add realism to screenplays or novels. But it’s crucial to research local code usage to avoid inaccuracies. Using the wrong code can undermine credibility, especially with detail-oriented readers or viewers.

Key Takeaways and Next Steps

Understanding police code 27 begins with recognizing the lack of a one-size-fits-all definition. Its most common usage is as a warrant or wanted person check, but local variations abound. If you’re monitoring police traffic, writing fiction, or satisfying a curiosity, check your local resources for specifics.
