AddressReady validates shipping addresses during checkout using rules you configure. Block PO Box addresses; require a house number, postal code, or phone number; set minimum and maximum address lengths; and restrict selected characters. Choose whether each rule applies to all countries, selected countries, or excludes specific countries. Add a custom checkout error message for each enabled rule so customers know what to correct before completing checkout.
