Generally, all firearms purchases and transfers, including private party transactions and sales at gun shows, must be made through a California licensed dealer under the Dealer’s Record of Sale (DROS) process. California law imposes a 10-day waiting period before a firearm can be released to a purchaser or transferee. A person must be at least 18 years of age to purchase a rifle or shotgun. To purchase a handgun, a person must be at least 21 years of age. As part of the DROS process, the purchaser must present "clear evidence of identity and age" which is defined as a valid, non-expired California Driver's License or Identification Card issued by the Department of Motor Vehicles (DMV). A military identification accompanied by permanent duty station orders indicating a posting in California is also acceptable. If the purchaser is not a U.S. Citizen, then he or she is required to demonstrate that he or she is legally within the United States by providing the firearms dealer with documentation containing his/her Alien Registration Number or I-94 Number.
If the buyer is not a U.S. Citizen, then he or she is required to demonstrate that he or she is legally within the United States by providing to the firearms dealer with documentation that contains his/her Alien Registration Number or I-94 Number.
Purchasers of handguns must provide proof of California residency, such as a utility bill, residential lease, property deed, or government-issued identification (other than a drivers license or other DMV-issued identification), and either (1) possess a Firearm Safety Certificate (FSC) plus successfully complete a safety demonstration with their recently purchased handgun or (2) qualify for an HSC exemption.
