Dallas Police Department (DPD) Radio Codes and Signals Practice Exam 2026 - Free Radio Codes Practice Questions and Study Guide

In DPD radio practice, numeric codes quickly label the type of activity, so everyone knows what kind of incident is being discussed. Code 33 is used to indicate prostitution. This makes it the best answer because the code name directly matches the activity being reported, signaling the appropriate response, such as vice or undercover operations, and triggering the right procedures and units. The other activities—suspicious person, open building, and a dead person—are assigned different codes, so they wouldn’t be indicated by Code 33.
