Accurate address classification is essential for reliable order fulfillment. When businesses that ship exclusively to commercial locations receive residential addresses, it often leads to failed deliveries, unexpected carrier surcharges, operational delays, and poor customer experience. Residential Address Validation helps prevent these issues by ensuring that customers enter only eligible, non-residential addresses at checkout.
Why Residential Addresses Matter
Many carriers treat residential deliveries differently from commercial ones, often applying additional fees or restrictions. If a business does not support residential delivery, accepting these addresses can result in:
Failed or rejected shipments
Additional residential delivery surcharges
Manual order reviews and address corrections
By identifying residential addresses early in the checkout process, businesses can eliminate these problems before an order is placed.
How Residential Address Validation Works
When enabled, the Residential Address rule automatically evaluates each delivery address entered during checkout. If the address is identified as residential, the system prevents the customer from proceeding and prompts them to provide a valid non-residential address.
Valider leverages a world-class database and collaborates with industry-leading address validation providers, including USPS, FedEx, DHL, and other trusted shipping partners, to ensure the address is verified with the highest level of accuracy and reliability.

Key Features
Universal Rule Execution
The rule applies universally, without the need for additional conditions. Once activated, every checkout address is automatically validated for residential status.
Inline Error Messaging
Error messages can be displayed directly below the address input field or top of the Checkout page, allowing customers to immediately understand and correct the issue without confusion.
Custom Error Messaging
Businesses can tailor the message shown to customers, for example:
“We cannot deliver to a Residential address.”
This ensures clarity while maintaining a consistent brand tone.

Conclusion
Residential Address Validation is a proactive safeguard for businesses that do not deliver to residential locations. By enforcing this rule at checkout, merchants can reduce failed shipments, avoid unnecessary carrier fees, and streamline order processing. It ensures that only eligible addresses move forward—protecting both operational efficiency and customer satisfaction.
