I thought "coded ammo" was where the bullet and casing have matching serial numbers/markings from the manufacturer that are tied to a purchaser at the time of sale, while microstamping puts the imprint on the casing only at the time it is fired. Am I incorrect? Thanks for any info.

Sounds correct:

"Coded ammunition" = serialized ammunition

Microstamped is as above.
