Once you've found a store that does age verification properly, stick with them. Here are a few rules to help you navigate the process and avoid issues:

1. Keep your ID handy. If you're shopping on your phone, have a digital copy or your physical license ready. That makes the upload step painless.
2. Use the same address everywhere. Verification services often check that your billing, shipping, and ID all match. If you've moved recently, update your info first.
3. Don't share your full SSN. If a site asks for more than the last four digits, stop shopping there.
4. Check the privacy policy. It should say how long they keep your data and what they use it for. If it's vague, that's a red flag.
5. If verification fails, contact support. Sometimes it's a simple typo. A legit business will help you sort it out.

These rules apply whether you're buying a simple refillable pod device or a disposable that lasts a few weeks. The verification process is the same across the board.
