The Identification Unit (previously known as the Central Identification Bureau and Central Identification Services) is a 24/7 operation which processes incoming Live Scan arrest submissions from every agency within Contra Costa County in order to verify the identity of subjects in custody.

A notification is then submitted back to the arresting agency with any differences being noted so that proper warrant checks can be conducted.

The Identification Unit serves as the county’s Custodian of Records, housing all arrest fingerprint records for Contra Costa County. The local Automated Fingerprint Identification System (AFIS) is comprised of arrest fingerprint Tenprint cards from Contra Costa County as well as Alameda County with funding being supplied by the Regional RAN Board. Contra Costa County has a staff of Fingerprint Technicians as well as Supervising Fingerprint Technicians who work around the clock to provide services to the public and law enforcement agencies.
