Address Validation
Automatically checking that a customer's shipping address is deliverable before fulfillment.
Definition
Address validation tools check shipping addresses against postal databases to confirm they are deliverable — flagging incomplete, incorrect, or unrecognized addresses before an order ships. Apps like Address Validator for Shopify automate this process.
Why It Matters for Shopify Brands
Undeliverable address orders result in returned packages, redelivery costs, and angry customers. Address validation at checkout or order review prevents this by catching errors before fulfillment.
Benchmarks
Undeliverable address rate without validation: 0.5–2%. With validation at checkout: under 0.1%. Each undeliverable package costs $5–$20 in redelivery or return costs.
