GazChap's WooCommerce getAddress.io Postcode Lookup is a free WordPress plugin designed to enhance the checkout experience for UK customers. By allowing users to enter their postcode and select their address from a list, it simplifies the billing and shipping address input process. This plugin integrates with the getAddress.io service, utilizing the Royal Mail Postcode Address File to ensure accuracy and efficiency. Users can enable or disable the address lookup feature for both billing and shipping addresses in the WooCommerce settings.

The plugin requires a valid getAddress.io API key and is compatible with WooCommerce version 3.0 or higher. It saves looked-up postcodes in a custom database table for 24 hours to minimize API costs. While it currently does not support WooCommerce Checkout Blocks introduced in version 8.3, future updates aim to enhance its compatibility. The plugin also includes customizable filters for developers and offers options to address conflicts with other plugins.
