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.

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.

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.

I’ve been using Validify for several weeks, and it’s been a great help for my store. It keeps customer data accurate and clean, and the support team is always helpful when I need them.

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.

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.

Toller Support! Ein gewünschtes Feature wurde innerhalb von wenigen Stunden direkt implementiert vom Entwickler!! (Regex Prüfung in Adresszeile 2, abhängig von dem was in Adresszeile 1 steht -> Auf korrekte Postnummer prüfen, bei Packstation.) Nur zu empfehlen!

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.

It's going really well, I'm new to this, it's true that if the menu was translated into Hindi it would be better, but I also understand...basically everything is great so far.
