Like Browning, Winchester, Remington, marlin, Mossberg, and dozens of other major manufacturers, Colt offers verbal, (telephone) date of manufacture service. FREE

Colt has a detailed certification archive service that costs $100 or so, but that is used to authenticate collector pieces like the SAA's or similar where the date of mfgr. mean a difference of $1,000's in a  cowboy SAA.
