When clearing from a call, is a suffix added to the IDF code?

• A. No suffix is ever used
• B. Suffix is optional
• C. A suffix must be added to the IDF code when clearing from a call
• D. Suffix is used only for certain calls

Answer: (C)

When you clear from a call, adding a suffix to the IDF code communicates the final status of that incident. The IDF code on scene shows what happened and what actions are in progress, and the suffix flags that the call has been completed and the unit is returning to service or freeing up resources. This keeps radio traffic and the incident log unambiguous, so dispatch, supervisors, and other units know immediately that no further action is required on that call. Because this final status needs to be consistently recorded for every clearance, the practice is to include a suffix each time, not just sometimes or for only certain calls.
