See every featureAddressMate Address Validator helps merchants prevent invalid or restricted shipping addresses at checkout. Create custom rules based on ZIP, postcode, country, state, or multiple fields. Display clear error messages before orders are completed. Test rules safely before activation and support translations. Improve delivery accuracy and enforce shipping policies without editing theme code.
GateKeeper blocks orders shipping to US states or ZIP codes you restrict. Rules run inside checkout as a validation function, so customers cannot bypass them. Restrict all products, or only products with specific tags, and add large ZIP code lists: one rule can cover every US ZIP code. When an order is blocked, the customer sees a message you write.
