Getting started
Install, test with a bad address, and pick a plan.
- Getting started: setup after install
Address Verifier ships with working defaults. Three steps stand between install and your first caught address: set your rules, then add the block to your thank-you and order status pages.
- Warn vs Block: what Address Verifier stops, and where
Every rule runs in one of two modes. Block stops the address at checkout. Warn lets the sale finish and asks the buyer to fix it right after paying. Here's how to choose.
- Test Address Verifier with a bad address
The fastest way to trust the app is to watch it catch something. Here's what to enter, what each surface should show, and how to check the result landed on the order.
- Free vs Pro: which plan you need
Free enforces your address rules at no cost, forever — blocking at checkout, warning buyers after purchase. Pro adds real verification — every address checked for deliverability against carrier and postal data — plus the suggested fix at $0.04 per order. The difference is whether addresses are confirmed deliverable or only policy-checked.
