Advanced Zipcode Validator
The reviews are overwhelmingly positive, with merchants repeatedly praising the app’s core functionality for zipcode/pincode validation, delivery availability checks, and estimated delivery messaging. Many users say it is easy to set up, integrates smoothly with Shopify, and helps improve customer experience, reduce failed deliveries, and save time by preventing unserviceable orders or unnecessary refunds. A major highlight is the support team: reviewers consistently describe the team as fast, responsive, knowledgeable, patient, and willing to go above and beyond with troubleshooting, customizations, and even live calls or direct implementation help. Negative feedback is limited, but a few users mention setup complexity in certain cases, especially when custom code changes or popup widget adjustments are needed. One reviewer noted that a more guided setup would help non-technical users, and another requested additional delivery-estimator features such as cutoff times and holiday mapping. Overall, the app is seen as reliable and effective, with the main area for improvement being more out-of-the-box guidance and a few missing advanced features.

Extension is working perfectly, and team support is very good.
We encountered accessibility issues with the app and contacted AJ for support. Umang and the team have been incredibly supportive and diligently worked with us to make the app more accessible for all users. Thanks for being an excellent partner!
Absolutely outstanding support! Umang and Anil were incredibly helpful, professional and reliable. They identified the issue within a very short time and managed to fix everything perfectly. What impressed us most was how responsive and well organised they were. As soon as they had found and resolved the problem, they immediately got back to us, and only about 30 minutes later we were already in another Google Meet together to check everything. Everything worked exactly as it should. Fast, friendly, competent and truly solution-oriented support. We are extremely happy with the service and can absolutely recommend the Advanced Zip Code Validator app and especially the amazing support from Umang and Anil. Thank you so much for your help! ★★★★★
