Let’s start by nailing down the basics.
Police Radio Codes: A Quick History
What Are Police Radio Codes?
Police radio codes are standardized signals used by law enforcement to communicate effectively over radios. Their core purpose is minimizing radio chatter, protecting sensitive details, and speeding up responses. While “10-codes” (like 10-4) are the most famous, agencies also use numeric and “signal” codes.
Why Were Codes Developed?
The primary reasons for radio codes are:
- Brevity: Short codes take less time to speak than full sentences.
- Clarity: Codes reduce misunderstanding in noisy or tense environments.
- Operational Security: Coded language prevents the public from easily deciphering sensitive police actions.
Agencies began adopting codes as early as the 1930s, with 10-codes gaining popularity in the 1940s thanks to the Association of Public-Safety Communications Officials (APCO).
Do All Police Departments Use the Same Codes?
No. While many departments in the U.S. initially used APCO’s original 10-codes, the list has evolved. Departments also developed their own region-specific codes to address local incidents, leading to a patchwork of meanings.
Police Code 23 Unpacked
What Does Police Code 23 Mean?
The meaning of “code 23” can depend on geography and agency. However, in many U.S. law enforcement contexts, the most widely accepted meanings are:
- Code 23: Missing person (in several states, including Florida and Oregon)
- Alternatively, some departments assign “code 23” to “Drunk Driving” (found in select regional code lists)
- It may also refer to a general “Arrived at Scene” or “Arrived at Location” in some emergency response teams
It’s essential to note that police code 23 does not have a strict, national definition. Always check the specific jurisdiction’s code list for accurate interpretation.
Examples in Practice
- Florida: Code 23 = Missing person (as per Florida Department of Law Enforcement)
- California: “23” is generally not standardized, but individual agencies might assign it ad hoc
- Scanner Apps: You’ll find “code 23” flagged for different incidents, usually matching local usage

Why All the Variation?
Police codes were intentionally designed to be flexible and customizable. Departments adjust them to fit local needs, crime rates, and procedures. This variability is one reason why movies and police TV shows sometimes get these codes wrong.
Decoding Police Radio Codes
10-Codes, Signal Codes, and Plain Language
Police radio language falls into three broad categories:
- 10-Codes
Like “10-4” (message received) or “10-20” (location).
- Signal Codes
Unique to local agencies, often numbered (“Signal 23”).
- Plain Language
Some newer agencies now minimize code use in favor of plain English for clearer communication, especially in multi-agency emergencies.
How Are Codes Assigned?
Agencies decide what each number or signal means based on local priorities. For example:
- Rural departments might have many animal-related codes.
- Urban departments may detail homicide, burglary, and narcotics.
There are attempts to standardize codes regionally, but most remain unique.
Should Civilians Know Police Codes?
Benefits
- Transparency: Understanding codes can help community members and journalists follow emergency activity.
- Public Awareness: Real-time police scanners inform about possible dangers or emergencies.
- Civic Engagement: Awareness promotes trust and accountability in policing.
Ethical Considerations
Listening to scanner traffic is legal in most states, but be mindful:
- Don’t interfere with active police scenes.
- Do not use codes for impersonation or misleading others.
- Respect privacy and reporting rules, especially after sensitive incidents.
Frequently Referenced Police Codes
For context, here are other common police codes to know:
- 10-4: Message received/acknowledged
- 10-20: What’s your location?
- Code 6: Stay out of area / busy
- Code 99: Emergency – all units respond
