What information does purpose code Z provide in the NCIC?

Purpose code Z in the NCIC (National Crime Information Center) serves a critical function as it allows law enforcement agencies to access Criminal History Record Information (CHRI), including both conviction and non-conviction details. This information is integral for various law enforcement purposes, such as background checks and investigations, ensuring that officers have a comprehensive view of an individual's criminal history.

By utilizing purpose code Z, authorized users can obtain relevant data that assists in making informed decisions during various law enforcement processes. This includes understanding not only the history of convictions—where individuals have been found guilty of crimes—but also non-conviction information, which can be vital in assessing the context and background of an individual being investigated or screened.
