DS: Address Validation / Block

We installed Address Validify to clean up our checkout and it works perfectly. Customers are forced to enter accurate addresses, which has significantly reduced RTOs, delivery delays, and manual verification work for our team. The rules are very customizable, setup took only a few minutes, and it integrated seamlessly with our existing checkout. Their support team is responsive and open to feedback. If you rely on reliable shipping data, this app is absolutely worth it.

Does what it says on the tin! I am using the app at Shopify Plus checkout to help with a few address issues. Thanks to Parth for his speedy help with the set up and testing. Recommend.

Good app. It works as we expected. Their support service is also good.

Very good app, a lot of features and great support.

I was looking for an app that would allow me to block certain area from purchasing on my website and it does that well. I found it a bit hard to install the dev. and support team was fast and very helpful during that process.

Awesome app, works exactly as we needed it to. Simple to set up, and if you have difficulty they are right there, instantly helping you through every step with patience and clarity. I can't recommend every app this dev makes enough due to their outstanding customer service.

We are totally satisfied with the app. It makes exactly what we need. We had a little problem with validation of addresses for local delivery, but the support from the app was perfect and they updated the app really fast so it works for all kinds of delivery flawlessly.

This app is absolutely perfect.
We had been facing many difficulties due to address issues with our customers in Taiwan and China.
We needed local-language input, and thanks to this app, everything has been resolved.
I also want to express my gratitude to the person in charge.
Thank you once again — we truly appreciate it.

We've been using Validify for a few days, and it has significantly reduced incorrect shipping addresses. The app is super easy to set up and integrates seamlessly with our Shopify store. We particularly love how it catches missing house numbers and invalid PO Boxes, ensuring our shipments always go to the right place. The customizable error messages and multi-language support are a big plus! Highly recommend this app to anyone looking to improve their order accuracy and customer experience.

The app offers a wide range of options for restricting data entry across fields like address, name, and email. This is especially helpful for us, as we integrate our Shopify data with other systems that have stricter input requirements than Shopify. The team behind the app is responsive, easy to work with, and quick to assist with any requests or customizations.
