How bat stamps work
The stamp on the barrel (or taper) is what umpires check — not the brand name on the ad. This applies in every U.S. region.
USA USA Baseball (USABat)
Wood-like performance standard for most recreational / town youth baseball since 2018. Used by Little League, Babe Ruth / Cal Ripken, PONY, AABC, NABF (youth), Dixie Youth, Dizzy Dean (among others), and many park districts.
Look for: the permanent USA Baseball mark. Solid one-piece wood bats generally don’t need the mark.

USSSA USSSA BPF 1.15
