Not yet covered: Game Day USA (no bat rule found on its rules page), Dixie Youth, AABC, AAU and Nations Baseball. Each state page also lists the tournament operators found in that state.
All state associations follow NFHS Rule 1-3-2. A ✓ means we also checked that state's own document (CO, CT, NC, WA). WA allows USA and USSSA bats at the middle-school level.
BatCode lists current bats with their certifications and shows which of these rules each one fits.
One email for GloveCode, ArmRules, BatCode and BatRules: new glove and bat data, plus pitch-count and bat-rule changes. (Placeholder: signup is not connected yet.)
