Why address validation is crucial for Shopify merchants

The validation of postal addresses has become a critical component of any e-commerce business. Incorrect addresses can result from spelling mistakes, incorrect house numbers, hastily filled out forms and varying international formats etc. Having a reliable way to validate customers addresses is essential to reduce the number of orders that can’t be shipped due to invalid addresses.
