About King Checkout Validation
Our app blocks invalid checkouts by detecting missing house/apartment numbers, validating VAT/tax ID formats, and filtering non-Latin characters. Customize address validator rules for field lengths, keyword restrictions, or regex patterns—adapting checks to cart value, product types, and shipping zones. Streamline compliance, reduce return rates, and prevent failed deliveries through automated error blocking—all managed in one dashboard.
