1. "They looked old enough." — The #1 mistake. Never rely on visual estimation. Always card.
   Fix: Implement a strict "no ID, no sale" policy. Card everyone, no exceptions.
2. Glancing at the ID without really checking. — Quick glance at the photo, done. Fake IDs pass all the time this way.
   Fix: Train staff on the 7-step ID check process. Use ID scanners.
3. Not checking the birth date — just the year. — Someone born in December 2005 is still 20 in October 2026.
   Fix: Always check the full date. Use a scanner — it does the math for you.
4. Accepting expired IDs. — An expired driver's license is not a valid form of ID in most states.
   Fix: Train staff to check the expiration date. If it's expired, refuse the sale.
5. "I know them — they're regulars." — Familiarity breeds complacency. Staff skip ID checks for people they recognize.
   Fix: No exceptions policy. Even the owner gets carded. It builds muscle memory.
6. Staff not trained (or training forgotten). — New hires don't know the rules. Long-time staff get lazy.
   Fix: Formal training program. Quarterly refreshers. Mystery shop your own store.
7. No written policy or documentation. — If you don't have a written age verification policy, you have no defense.
   Fix: Write down your policy. Have staff sign it. Document training. Keep compliance records.
8. Ignoring online sales rules. — Online retailers often skip proper age verification or use only self-attestation.
   Fix: Use third-party age verification + adult signature delivery. Comply with PACT Act fully.
