Magento 2 - Checkout Address Validation by Smarty Extension

Please Note: Magento 2 Checkout Address Validation using Smarty API is an independent extension developed by EcomPlugins. It is not created, endorsed, or supported by Smarty. This downloadable Magento 2 extension integrates your store with the official Smarty Address Validation API to verify customer shipping addresses in real time and improve delivery accuracy.

This extension is part of our complete Magento Address Validation solution and works seamlessly alongside our Magento Shipping Integration extensions.

Smarty is a leading provider of address validation and location intelligence services. Trusted by organizations including Microsoft, Netflix, and NASA, Smarty provides fast and highly accurate address validation, standardization, geocoding, and autocomplete services across more than 240 countries and territories.

During checkout, the extension automatically validates the customer's shipping address by sending the complete address—including street, city, state, ZIP/postal code, and country—to the official Smarty Address Validation API. The API returns standardized and suggested addresses, allowing customers to select the most accurate shipping destination before placing their order.

If Smarty cannot validate the address, merchants can allow customers to continue using the original address or require address confirmation based on the module configuration. This flexibility helps balance customer convenience with shipping accuracy.

The extension also validates customer addresses when creating or editing entries in the Magento Address Book, helping maintain clean and accurate customer records throughout your store.

Review the screenshots below to see how Magento 2 Checkout Address Validation with Smarty API works during the checkout process.

Important: Before using this extension, you must have an active Smarty API account with valid API credentials. Ensure your account has access to the required Domestic or International Address Validation APIs.
