Klostermann Stahldesign GmbH review for Address Validator AddressHero

June 4, 2025

Absolutely essential app – finally a real solution to missing address details! We’ve struggled for years with customers forgetting to enter their house number during checkout – and unfortunately, Shopify never offered a proper fix. AddressHero solved this issue instantly. It automatically detects incomplete or incorrect addresses and prompts customers to correct them before the order is placed. Not only does it prevent missing house numbers, but it also blocks invalid characters and even works perfectly with express checkouts like PayPal. Since using AddressHero, we’ve stopped wasting time chasing customers for missing address details. It just works – smoothly and reliably. This app has saved us time, money, and frustration. Highly recommended!
