Address Validation Ninja

Great experience so far, Stephen from support team provided great solution to our needs. Recommend to try them!

Support is friendly, quick in responding and helps a lot!

Provides many options for restricting data entry for address, name, email, etc. This helps us as we integrate our Shopify data across systems that have more restrictive rules than Shopify does. The company is easy to work with and responsive to requests for help or changes.

As a user who values localization and translations in e-commerce stores, I was greatly disappointed with my experience using the Address Ninja app. Although the app promises the ability to translate all error messages, it turned out that this wasn't entirely true.
Main Points of Disappointment:

Limited Number of Languages: The app offers translations for only 10 languages, which is quite limited for a global audience.
Unfulfilled Promise: The app description states that you can translate "all error messages," which proved to be misleading.
Lack of Transparency: I only discovered the translation limitations after installation and attempted use.
Importance of Localization: For my online store, translations are crucial, so this shortcoming is a serious obstacle.
Inflexibility: When I contacted them about this issue, they cited "limitations" instead of offering a solution or timeline for improvements.

Conclusion:
While Address Ninja may offer other useful features, the lack of comprehensive support for translations is a major drawback. For online stores focusing on an international audience, I would recommend seeking alternative solutions that truly support multilingualism in all aspects of the user experience, including error messages.
I hope the Address Ninja team will take this feedback seriously and improve their language capabilities in the future. Until then, I'll have to look for a more reliable solution for my online store's needs.

Moving from the custom checkout validations we had in place on checkout.liquid to Shopify's new checkout extensibility, we needed a solution that could achieve the same level of customization we previously had in place. Address Ninja was super easy to set up and their support team was top-notch as well.

Address Ninja is fantastic! It has streamlined our address management process and significantly reduced errors. The user interface is intuitive and easy to use. Their support team is top-notch, always responsive and helpful. Highly recommend! Exactly what we were looking for (and we've tested some others...)

SO easy to install (<2 minutes) and exactly what our store needed to block missing information when customers enter their addresses. Worth the price compared to other apps that cost ~$0.05/order, which for us would be over $25/month. Once I installed the app, their chat function (with a real human not a robot) assisted with the set-up. Would recommend!!!

Quick and efficient customer service. Highly recommend these guys!

The support is top notch not only do they understand their app well and it not being an outsourced team they really understand shopify and how to code within shopify. I recommend not only this app but the members of this team. 5 stars.

The application meets expectations for limiting unwanted characters when filling in emails. Fast communication and helpful support.
