The exact law, not a guess

Every answer cites the statute, links the official source and shows the text. No summaries you have to trust blindly.

Every restricted category

Knives, pepper spray, stun guns, ammo and firearm parts, vapes, alcohol, hemp and kratom, fireworks, batteries, PFAS products, sunscreen and more.

Down to the city

State law plus city rules in places like New York, Los Angeles, San Francisco, Chicago and Denver, matched by ZIP code.

Stops bad orders at checkout

Our Shopify app (coming soon) blocks orders that can't ship before the customer pays. Any platform can use the API today.

Ahead of the changes

Laws with future start dates, a public changelog, and email alerts when a rule changes for what you sell.

Honest about gaps

Where a state's code isn't openly available, we say "not covered yet" instead of "can ship". See exactly what we've checked.

  1. Where it's going. Destination ZIP or state, and where you ship from.
  2. What it is. Pick the product type and a few details.
  3. The answer. Can ship, age check, license needed, or can't ship, with the law behind it.

Rules are written from official statute text and applied, including drafts not yet reviewed by a lawyer (labelled as such). Accuracy isn't guaranteed; report a problem from any answer. Information, not legal advice.
