What is the purpose of the code 10-3?

The purpose of code 10-3 is to instruct personnel to call the dispatcher by telephone. This code is typically used in scenarios where radio traffic may be heavy, unclear, or when a critical matter needs to be communicated without the potential interference or delays of radio transmissions. Calls to dispatch ensure that important information can be conveyed directly and effectively, allowing for clear communication and coordination among officers.

The other codes serve different functions; “standby” indicates that an officer should be waiting for further instructions, “repeat message” requests that the last transmitted information be repeated for clarity, and “verify address” is used to confirm the accuracy of a location. Each code is essential in its own context but does not fulfill the specific communication purpose that code 10-3 does.
