That's not how it works. Your supplier's license doesn't cover your own selling activities. In California, each retailer—even an online one—needs their own tobacco retailer license. You also need to follow local laws in the cities where you ship. A supplier being licensed is a good sign, but it doesn't substitute for your own compliance checks.

Also, licenses can expire or be revoked. Don't assume a license is current just because the supplier shows you a copy. Look up their license on the California Department of Tax and Fee Administration (CDTFA) website to confirm it's active.
