With Address Validation, your customer only needs to enter their postal code and house number, or for an international address, just the first address line during checkout. The street name and city are then filled in automatically. The installation takes about five minutes and consists of five steps.
What you need:
The Address Validation app (typically installed in your Shopify store);
An account on the Postcode Checkout Dashboard with a compatible data provider (click here to view all our available providers);
Administrative access to the checkout.
This guide includes images. The red numbers and arrows in the screenshots indicate where you should click, following the sequence of the steps.
