Why sellers trust it
- Official sources. Every rule is written from official statute text and links it.
- Monitored monthly. Official sources are re-checked every month; every change goes in the public changelog.
- Honest about gaps. Where a state's code isn't openly available, we say "not covered yet" instead of "can ship". See what we cover.
- Not legal advice. Drafts not yet reviewed by a lawyer are labelled as such. Accuracy isn't guaranteed; report a problem from any answer.
