    Automatically validate shipping addresses to reduce carrier fees and prevent failed deliveries

    Did you know carriers like UPS/FedEx/DHL may charge you $19-$25 for something as small as a period next to the letter N for “North” in a street address? It sounds absurd, but it’s real. Shopify’s Google auto-complete helps fill in addresses, but it does NOT verify if they’re deliverable—leaving you vulnerable to lost packages, reshipping fees, and customer service requests. Get started in less than 5 minutes and begin to save on carrier fees today.

    • Prompt customers to fix bad addresses and offer smart suggestions instantly
    • Block undeliverable addresses like PO Boxes, missing apts, and special chars
    • Hold undeliverable orders before they hit your 3PL—no more paying for mistakes
    • Catch outdated addresses post-checkout, so your package lands in the right hands
    • Improve data accuracy with built-in Email and Phone Number Verification

    Pros

    • Verify, standardize, cleanse, and format addresses for over 240 countries
    • Supports multi-language functionality, accommodating 9 languages across customer touchpoints
    • AI rules engine prevents shipments to over 15 different problematic address types such as PO Boxes, non-contiguous US states, and military addresses
    • Allows creation of custom checkout rules to prevent special characters before order completion
    • Prompts customers to correct addresses when issues are detected, offering real-time suggestions
    • Creates rules to ensure undeliverable addresses (PO Boxes, missing house numbers, etc) are flagged
    • Automatically holds orders that identify as undeliverable before they are sent to a 3PL (third-party logistics)
    • Tags orders with address status and applicable rules automatically
    • Customization options for address prompts and email notifications to match brand aesthetics

    Cons

    • May require additional setup and configuration to fully customize and integrate with existing systems
    • Dependence on accurate initial data input; errors in entered address data might still require manual correction
    • Potential limitations in handling complex or non-standard international addresses despite broad country coverage
    • Relies heavily on the AI rules engine which may not be 100% accurate in all scenarios

    Does exactly what I need. We were having issues with non-latin characters at checkout, incorrectly auto-filled addresses, and then customers who didn't realize this until it was too late, their package was shipped. All better now.

    We’ve been using this app to address a persistent issue with invalid customer inputs, and it has been a game-changer. As a business utilizing a 3PL, we often encounter orders flagged with “action required” due to invalid addresses. Resolving these manually was tedious and inefficient. This app has streamlined the entire process, saving us time and hassle. On top of that, their support team is outstanding—responsive, knowledgeable, and always willing to go the extra mile. Highly recommend for any business looking to optimize their order flow and reduce manual intervention!

    Installed the app for address block and it really does its job. I see more potential and happy to dig further. Highly recommended!

    Wonderful and robust app. Even if you're on Shopify Basic Plan it can be immensely useful, allowing you to create powerful rules. A very clever thing is that in your Shopify Admin➔Checkout➔Checkout rules, only one rule is shown that includes all the rules created with this app. I would like to thank Ryan, who was kind and helpful.

    I recently tried the Wrong Address Checker app, and it’s been a game-changer for my Shopify store. This app automatically checks for incorrect shipping addresses before orders go through, which has saved me tons of time and stress.

    An amazing app that's been invaluable since we downloaded it. Exceptional customer service and amazing offering that's the perfect fit for our store. As a gifting business we frequently saw address errors (street number missing) and incorrect delivery addresses where customers inadvertently send their order to themselves instead of the intended recipient, this app offers a solution to both and it works amazingly well - even with an express checkout. Ryan and his team offers speedy execution for new ideas, and a seamless design for customers that doesn't hinder the checkout experience. I strongly recommend you give this app a try.

    The Address Guard team has been super responsive and helpful during the implementation process. They even helped build us a couple custom tools which was very helpful! So far so good and happy to have chosen them!

    If I could give 6 stars I would. Their response to issues is always prompt, they have fixed any issues within a day and provide custom updates in a very reasonable time. The address verification is great and can verify orders from sources other than the Shopify checkout. Could not be happier with this application.
