Ultimate Postal Code Blocker

Feb. 1, 2026

This app is working well for our business. We had some minor issues with the initial integration but the app owner had zero issue helping to resolve the problems.

Works perfectly, The CSV I uploaded initially contained too much information so a good tip is to only include the postal codes you need blocked and not adding the city name in a separate column as this caused the entire city to be blocked for myself. Contacted their help and received a phone call within 10 minutes as their emails weren't going through but I had managed to fix the issue myself as the app is that easy and intuitive to use

Very easy to install. I was looking for an app that would allow me only to send to the major cities in Canada so I didn't receive unexpected remote delivery charges. The developer quickly added a whitelist option to the whole country blocking, which was a very quick and elegant solution.
