Which code represents a request for a specific location?

The correct choice for a request for a specific location is represented by 10-20. This code is used in law enforcement communications to ask or indicate the current location of a person or unit. Understanding this code can enhance spatial awareness and coordination during various operations, ensuring that officers can effectively respond to incidents or communicate their whereabouts to dispatch or fellow officers.

In contrast to this code, other options represent different meanings; for instance, 10-21 typically requests a phone call, 10-23 is used to indicate that an officer is on the scene, and 10-30 refers to an inappropriate or unlawful situation. These distinctions highlight the importance of knowing specific codes for clear and efficient communication in police work.
