Clearer.io Address Validator

We were looking for some help in reducing USPS lost orders and wanted an app that sat BEHIND the checkout so that it didn't impact our conversion rate. Address Validator did exactly this and we're very happy with the service, support, and customization options. Highly recommend for any high-volume stores looking to minimize customer support inquiries for "where's my package" :P

Implementing this app has minimized the PO Boxes being submitted on orders as well as reduced the fees for address corrections. The Address Validator Team goes above and beyond to make sure we are fully optimized with the settings both in the initial setup and after a 3 month analysis. They are very quick to respond to any questions we may have. This app is highly recommended.

1. Use in Canada cause too many unnecessary notification, 2. The changes made after the order placed, which mean the order notification email from Shopify store, doesn't have the changes. 3. After every order, you need to login to the store to see the correction. After great support from "Address Validator" team my issues resolved to my satisfaction, and I am changing my review to 5 stars

5 stars from AlarmSystemStore.com
A key app that everyone should have as it will save you $ from expensive change fees from UPS. Customers often mess up their address or input a wrong zip. This adds a layer of protection against that getting to UPS who will automatically charge you an expensive address change fee.

My interaction with support has been above and beyond as well. Great app and responsive support!

The app works out of the box and saves us a lot of problems when it comes to errors in shipping addresses. There are a lot of options related to what type of shipping address you permit so that is great. I wish the interface was easier to figure out... It's a bit of a weird UI and can be hard to customize because of this. But they have great and fast customer service so if you ned help they are ready to serve you.

I've been using this app on all 6 of my Shopify stores for about a week now. It's easy to set up and configure. It's only been a short time, but it's already paying dividends with catching several orders from customers that didn't input their address correctly (missing apartment number, suite number, etc). With UPS charging $16 per address correction, this app quickly pays for itself and then some! I highly recommend it.

Early days for us with the app but the initial indications suggest it has been a good addition for us.
We have had a number of issues with EU customers getting confused with address formatting in our Shopify checkout and this has resulted in carrier returns.
We have also been able to block pack station delivery addresses which has been helpful.
So far so good.
The guys at Roboturk were very helpful in guiding us through the initial set up.

Very useful app. Our 3PL warehouse can't accept more than 55 characters for the address line 1 field — with this app we can limit the characters and show a custom error message. Additionally, we're starting to ship more internationally and found some city addresses can't be longer than 30 characters. It's not possible to limit the city field independently, but the app developer quickly added this for our convenience. The support has been very top-notch!

We use this app to help reduce address submission errors, most importantly for international orders. It has helped us reduce the amount of user submission errors, reducing the manual work required on our side when a user enters an invalid address. The Team has also been extremely helpful in helping us solve issue and even building out new features to improve the app and help us overcome some of the more common validation issues we experience. 5 stars!

Address Validator has worked well for us. When I had an issue they responded immediately, which is unusual given our timezone and uploaded the applicable code I needed. I felt their customer support was excellent! We have just activated the warnings for "no street number" and "address to long". Hopefully, this will reduce how many times we have to manually intervene when the order fails to flows through to our CRM because of bad data entered by the customer.
