With Address Validation, a customer's shipping address at checkout is validated with prominent shipping carriers such as United Parcel Service (UPS) and United States Postal Services (USPS). Should the customer's address be incorrect and they enter a wrong zip code, for example, then a suggested address that is known to the shipping carriers would be displayed to the customer. From there the customer can confirm if the suggested address is correct or if they would prefer to use the address they have provided. 

The extension, with either UPS or USPS, helps to ensure that the addresses are valid so it will prevent the appearance of orders that can't be delivered. Address Validation for Magento 1 can validate a shipping address with either UPS or USPS. Once the customer enters their shipping address on the checkout page, the address will be confirmed with UPS or USPS.



  • Enable/disable option for a customer to place an order with an incorrect address
  • The suggested address is shown to the customer if the address does not match
  • Customer can choose to continue checkout with their original address
  • To prevent orders being shipped to invalid addresses, the extension checks the customer's address 
  • Select and quickly change shipping information to the correct address. 
  • Enable the solution and specify if you would like to permit customers with an invalid shipping address to place orders. 
  • Specify to show residential or commercial classification when suggesting valid addresses to customers


Reduces Shipping Costs

Instead of spending money on shipping products to invalid addresses that are returned to your store, the Address Validation extension eliminates this process by ensuring shipping addresses are confirmed with prominent shipping carriers.
