My friend recommended this app to me. So far, it's been great! The app's interface is nice and very easy to manage, and it comes with excellent support and complete instructions. Every Shopify eCommerce store should use it—it’s extremely helpful in preventing invalid addresses and saving both shop owners and customers from potential issues. I strongly recommend it!

This is an excellent app, to be honest. Everything was set up in 2 minutes, and bump... It's done. The app will help you to prevent failed deliveries and save a huge cost. The support agent was very quick and helpful in response, thank you.

Valider is likely the best app that can solve any address-related issues e-commerce stores have to deal with on a daily basis. Whenever an address issue happens like bad formatting or forgotten details, Valider instantly informs customers on the Thank you page that changes need to be made. Looking forward to getting email notifications in the upcoming release.

Moved here from a terrible app. This app is much easier to use, clean UI and clear UX. And most important, it works very well without any issues.

Couldn’t get the app to validate any of my orders, and it kept giving me this weird error message on my checkout page. I tried to email support but nobody has responded in 3 days - not sure if they’re in business or not.
