If you’ve ever listened to a police scanner or watched a gritty crime drama, you’ve likely heard officers communicating in a series of “10-codes.” These shorthand signals allow for quick, clear communication over radio frequencies. One of the most frequently used signals is 10-7. But what exactly does it mean when an officer goes “10-7”?
In this article, we’ll break down the meaning of police code 10-7, its variations, and why these codes are still vital in modern law enforcement.
The Short Answer: What is 10-7?
In the official APCO (Association of Public-Safety Communications Officials) ten-code list, 10-7 means “Out of Service.”

When an officer broadcasts “10-7,” they are notifying the dispatcher and other units that they are currently unavailable for calls. This doesn’t necessarily mean they are off duty for the day; it simply means they cannot respond to a new emergency at that specific moment.
Common Scenarios for Using 10-7
An officer might go 10-7 for several reasons throughout their shift. These include:
- End of Watch: The most common use is at the end of a shift. When an officer’s workday is over, they log off by going 10-7.
- Meal Breaks: Officers need to eat. Often, they will radio in as 10-7 (sometimes followed by a location) to indicate they are taking their lunch or dinner break.
- Mechanical Issues: If a patrol car breaks down, has a flat tire, or needs radio repairs, the officer is 10-7 until the vehicle is functional again.
- Administrative Tasks: If an officer needs to go into the station to process evidence or complete paperwork that requires their full attention, they may go out of service.
- Personal Breaks: Routine stops for fuel or restroom breaks are also categorized under this code.
Regional Variations and Sub-Codes
While 10-7 generally means “out of service” across North America, some departments use suffixes to be more specific:

- 10-7B: Often used to specify a meal break (B for “Break”).
- 10-7C: Used in some jurisdictions to indicate the officer is out of service for “Case Work” or “Court.”
- 10-7 OD: Out of service, Off Duty.
It is important to note that not every police department uses the same code system. Some agencies have transitioned to “Plain Language” (speaking in clear English) to avoid confusion during multi-agency responses, but the “10-7” remains a staple in police culture.
The Emotional Meaning: The “Final 10-7”
In law enforcement culture, 10-7 carries a deeper, more symbolic meaning during funeral services. A “Final 10-7” or “End of Watch” (EOW) call is a radio ceremony performed for an officer who has retired or, more solemnly, for an officer killed in the line of duty.
The dispatcher will call the officer’s unit number over the radio several times. When there is no response, the dispatcher will announce that the officer is “10-7 for the final time,” signifying their service has ended and they are “going home.”
Why Use Codes Instead of Plain English?
You might wonder why police don’t just say “I’m going to lunch.” There are three main reasons:
- Brevity: Radio airtime is precious. “10-7” is faster than saying “I am going to be unavailable for the next thirty minutes.”
- Clarity: In high-stress situations or areas with poor radio reception, short, distinct codes are easier to understand than long sentences.
- Privacy: While the public can listen to scanners, codes provide a small layer of professional distance and privacy for routine administrative movements.

Conclusion
In the world of law enforcement, 10-7 is a fundamental signal of transition. Whether it’s an officer heading to a well-deserved meal break, a patrol car needing repairs, or a solemn tribute to a fallen hero, “Out of Service” is a phrase that keeps the department organized and the lines of communication clear.
