Customers can correct their delivery address after ordering

Edit delivery address lets customers fix their delivery address on the thank-you and order status pages. Tacey checks the street, city, region and postal code together before saving, uses Shopify's own list of states and provinces for every country, checks the postcode format, catches a state that does not match the postal code (including Brazilian CEPs), and points at the field that is wrong with a one tap fix. Your "Show a suggestion" setting (Always, Only when something looks wrong, or Never) controls what customers see, you can block addresses we cannot confirm, and a small badge on the row tells the customer when their address needs a look. If Shopify refuses a change, the customer is told why. If you change the same address in Shopify while the customer is saving, the fields they did not touch keep your change, and a customer who tries while you are mid-edit is asked to try again in a moment. Customers in countries without postcodes, such as the United Arab Emirates, Hong Kong and Qatar, can use the order tools too.
