Which code number represents 'Call by Telephone'?

• A. 10-21
• B. 10-22
• C. 10-23
• D. 10-24

Answer: (A)

Knowing how 10-codes map to actions in police radio communications helps you quickly interpret requests and statuses. The code for making a telephone call is 10-21, which signals a call by telephone when an officer needs to reach someone by phone or relay information orally over the line. The other codes in this set are tied to different operations (not a telephone call), so they don’t fit the meaning of “Call by Telephone.”
