When I entered an address with unusual wording, I got a clear message explaining why it couldn’t be accepted. It felt professional and gave me confidence in the store’s process.

The ability to customize error messages is a big win. Shoppers see friendly, clear prompts, and I avoid confusion. It’s seamless with Shopify checkout and works across all plans.

This feature has been a big help for avoiding failed deliveries. It immediately alerts customers when they enter a PO Box, so they can switch to a valid address before completing the order. The detection is accurate, covers all variations, and fits naturally into the checkout without disrupting anything.

Finally a solution to a long-standing issue! We used to spend hours emailing customers to correct PO Box addresses. Since installing ‘No PO Box,’ those problems are gone. It’s proactive, professional, and makes our shipping policy clear upfront. Couldn’t be happier with the results.

Brilliant app! Simple but powerful. It integrated perfectly into my checkout process, and customers now clearly see that PO Box addresses aren’t accepted. No more chasing down customers after the fact. The detection feature is super accurate—it catches all forms of PO Box entries. Worth every penny.

This app solved a major headache for my store! Before, we kept getting PO Box orders that we couldn’t ship to, which delayed deliveries and upset customers. Now, the app automatically catches any variation of ‘PO Box’ at checkout and alerts the buyer instantly. It works seamlessly and has saved us time, stress, and unnecessary refunds. Highly recommended!

I was paying over $100 a month in processing fees for PO Box orders. Even though I refunded an order I still lost on the fees! These fees added up for me.
