The 10-47 police code most commonly means “complete assignment quickly” — a dispatcher’s instruction for an officer to wrap up what they are doing and become available for the next call. It is not a code for a traffic accident, despite what many websites claim. And because 10-codes are not standardized nationally, a handful of agencies assign 10-47 a different meaning entirely.
What “Complete Assignment Quickly” Actually Signals
When a dispatcher transmits 10-47 under the most widely used definition, the message is prioritization, not description. The officer is being told to finish the current task so they can move on to something more pressing. There is no incident type attached to it. No crash, no suspect, no address. It is a directive aimed at the officer rather than a report about the world.
That makes 10-47 fundamentally different from the codes that describe what is happening on the ground. If you hear it on a scanner, the useful information is usually in the surrounding traffic: what the officer was doing, and what call they are being redirected toward.
Why the Meaning Isn’t the Same Everywhere
Police departments across the country modified the original 10-code list to fit local needs, and the same number can carry different meanings from one agency to the next. At least one published code list defines 10-47 as “emergency road repairs” — a report of a road hazard, which has nothing to do with telling an officer to hurry up and finish a task.
This variation is not a rare quirk. The Federal Emergency Management Agency has pointed to inconsistent 10-code meanings as a real problem when officers from multiple agencies need to coordinate on shared channels. If you want certainty about what 10-47 means in a specific jurisdiction, the only reliable answer is the code list published by that department. Many agencies post theirs on their official websites.
The Common Confusion With 10-50
A lot of online sources list 10-47 as “vehicle accident” or “vehicle disabled.” That definition almost certainly belongs to 10-50, which appears as “vehicle accident” on multiple widely used code lists. The error seems to have spread through websites copying one another without checking department references.
If what you heard on a scanner was clearly tied to a crash, the officer was far more likely transmitting 10-50 than 10-47. You might also hear 10-51 in the same sequence, which many departments use to mean “dispatch a wrecker” or “tow truck needed.” A 10-50 followed by a 10-51 fits the arc of a real traffic incident in a way that 10-47 does not.
If You Heard 10-47 on a Scanner
The most likely explanation is routine: a dispatcher told an officer to finish up and move on. It is not an incident code in most systems. Check whether the department you were monitoring publishes its 10-code list, because the specific meaning depends on the agency.
Scanner traffic without context can mislead. A single code rarely tells the whole story, and the same transmission usually includes unit numbers, locations, and additional codes that shift the picture. Agencies that have moved away from 10-codes toward plain language make this easier, since officers simply say what they mean instead of using numeric shorthand that changes from one county to the next.
