To indicate that a message has been received, which code would be used?

The code used to indicate that a message has been received is 10-26. This specific code is standardized within law enforcement communication to confirm receipt of information, ensuring clear and efficient communication among officers.

In the context of law enforcement operations, using a dedicated code helps maintain brevity and clarity in radio transmissions, which is crucial in time-sensitive situations. The ability to quickly acknowledge the receipt of messages promotes smoother coordination during operations and enhances overall situational awareness.

The other options represent different meanings; for instance, 10-25 typically refers to a request for a telephone call, while 10-23 denotes that an officer is on the scene, and 10-29 usually indicates a check for wanted persons or stolen property. None of these codes relate specifically to confirming message receipt.
