Made our first app: ZipCode Checker

With this app, you can seamlessly integrate zip code validation into your Wix Store. The app also allows you to restrict checkouts: if a user enters an undeliverable zip code, they will not be allowed to complete the checkout process. Thousands of zip codes can be uploaded via csv file.

Along with that plugin widget can be added to Product Page, letting users verify if their location is serviceable— each zip code can be customized with message displaying estimated delivery times or local greetings. A general widget is also included, placeable anywhere on your site.

Would love to have feedback, if anyone’s interested. Happy to share coupon codes for testing! Check it out: ZipCode Checker | Wix App Market | Wix.com

May I ask how your app validates ZIP Codes?
Is it through pattern matching, to see if the given code adheres to the rules set, or is it by looking up with actual address registries, and validating the ZIP code actually exists?

And, does this work for American ZIP Codes only? Or would 7-digits codes work? Will the pattern-matching/lookup change by country?

Right now, the app validates zip codes based on a list provided by the user. This means the user uploads a CSV file containing all the zip codes their store supports, and the app uses that list to validate entries on the website.

The app is flexible and works for zip codes from any country since it relies entirely on the user-provided list. It supports zip codes of any length—whether numeric or alphanumeric—without restrictions.

We’re also working on an exciting update, set to release soon, which will introduce support for adding zip codes via ranges and pattern matching.

Oh.. I thought the white-list CMS collection thing was a feature, not the way your app worked…

white list collection?

Hi - I am investigating if this will help me - this is my scenario. I have distribution points in 2 majpr cities in Australia. I am looking for the flexibility in wix to base the cost of delivery on the postcode provided by the customer. The States here are HUGE so the cost can vary significantly. Would this app give me the flexibility for example to set up a region called “Sydney Metro”, add in the relevant post codes and then base the delivery cost on this? thanks

With new version, we have added ability set pricing per zip codes. So you can do that. But if you want to set region wise rates, you can use Wix Shipping settings. There region wise rates can be set. Our app gives more granular level, setup extra shipping fees for each zip code!
