Hey Product Hunt!

I'm Felix and I recently launched a small but mighty Shopify app that helps stores prevent failed deliveries before they happen.

You know those annoying return to sender packages or customer emails like My address was correct, but I never got it! ? Yeah, that.

Address Validation iO checks and fixes addresses right inside the Shopify checkout no copy-pasting, no extra screens, no friction.

Hey everyone

A while ago, I kept getting failed deliveries and "return to sender" issues in my Shopify store. Most of the time, it was because of small address mistakes from customers missing house numbers, wrong postal codes, PO boxes in restricted areas, etc.

So I built Address Validation iO (AViO) a lightweight app that checks and validates addresses directly in the Shopify checkout. It s helped reduce shipping issues a lot and has saved us from refund headaches.

Would love your feedback if you ve dealt with similar problems or ideas on how to improve it. Also curious: How do you handle bad address entries in your store?

Hey Product Hunters,

We run a few Shopify stores and kept seeing the same problem: customers entering invalid or incomplete shipping addresses. That led to failed deliveries, returns, and annoyed buyers.

So we built a simple Shopify app that validates addresses right at checkout.
