What is Shipping Address Validator?

Customers often mistype shipping addresses and this leads to failed deliveries and ultimately, upset customers. Inaccurate shipping addresses may result in returned shipments and costly redelivery fees. Shipping Address Validator can help boost customer satisfaction by reducing the frequency of failed deliveries with:

  • Prompts that show suggested corrections or ask for alternative addresses
  • Emails & tags for orders created with invalid addresses

Key features

  • Mobile-friendly: The app is optimized for desktop and mobile devices to ensure a seamless consumer experience
  • Highly customizable: The prompts and emails can be fully customized to match your brand and identity
  • Prevent undeliverable addresses: Prompt customers to specify alternative addresses when undeliverable (ie PO Boxes, long addresses) ones are detected.
  • Tag orders: Automatically add custom tags to orders that have incorrect addresses to halt fulfillment
  • International: The app processes addresses in Australia, Austria, Belgium, Brazil, Canada, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Italy, Mexico, Netherlands, New Zealand, Norway, Portugal, South Africa, Spain, Sweden, Switzerland, United Kingdom, United States

Enable address rules to prevent:

  • PO Boxes
  • DHL Packstations
  • Parcel Collects
  • Missing street number or name
  • Non-Latin characters
  • Long addresses
  • Noncontiguous states
  • Military addresses


The prompts can be embedded into the checkout process only if you have Shopify Plus. Otherwise, they will appear on the Thank You page after checkout.


  • What orders will be processed? All orders in the covered countries that have not been fulfilled will be processed.
  • What orders will I be charged for? You will be charged for all orders processed even if the address is valid.
  • Can invalid addresses be blocked? Only if you have Shopify Plus, otherwise, the app can will prompt the customer to specify a new address after checkout
  • What is the cost? $0.04 per order after the first 100 orders. It's an additional $14.99/month if you want emails from your own domain.
  • How does it work with Google Autocomplete? Autocomplete is great for speeding up the checkout process but introduces errors like missing apartment numbers and incorrect house numbers. Address Validator checks to make sure the address is deliverable. The two products are very complementary.
