What message should the entering agency respond with after receiving a YQ message?

When an entering agency receives a YQ message, the appropriate response is the YR message. The YQ message is an inquiry about a specific record, typically to locate or verify information. The YR message serves as the acknowledgment from the agency that clarifies the inquiry's results or provides the necessary information regarding the status of the individual or property in question.

Responding with the YR message is crucial as it maintains the communication protocol within the NCIC system, ensuring that the queries and responses are accurately documented and tracked. This helps the originating agency to understand the outcome of their inquiry, enabling them to take the necessary next steps based on the information provided.

The other options do not align with the standardized communication process within the NCIC framework. Messages like "Locate," "Request," or simply "Response" do not accurately represent the formal reply needed after a YQ inquiry. The YR message is specifically designed for this interaction while ensuring compliance with NCIC operational procedures.
