At minimum Concealed Carry Weapons (CCW) applicants must provide their valid California driver’s license, proof of residency in the county such as a current utility bill, tax bill, voter registration, rental agreement etc. Vehicle registration is not enough. These documents should be uploaded during the CCW application process or provided to the investigator during the interview. Additional documentation, such as the firearm training certificate, can be added later by uploading it through the Order Tracker.
