What is the signal code for Bomb Threat?

• A. 73P
• B. 73
• C. 75
• D. 74

Answer: (B)

Understanding signal codes is about how officers label incidents in radio traffic with a concise numeric cue. This quick labeling lets responders grasp the situation at a glance and act without delays. For a bomb threat, the recognized numeric code is 73. Using this code immediately signals to everyone listening that a bomb threat is involved, prompting the standard response procedures, such as securing the area, coordinating with specialized units, and communicating with other agencies as needed. Other numbers point to different incident types, so they wouldn’t convey the specific threat here. A suffix like P on a similar code isn’t the standard way to denote a bomb threat in the regular code set. Memorize that 73 is the code used to indicate a bomb threat, so responders can mobilize appropriately and quickly.
