Filling out addresses manually can be frustrating for customers and lead to mistakes that cause missed deliveries. Our Postcode Lookup extension helps eliminate that problem – making it easier for customers to enter their address and more likely they’ll complete the checkout process.


Once installed, the extension allows customers to simply type in their UK postcode and select their address from a dropdown menu. No more worrying about mistyped house numbers or missing details, everything is quick, accurate, and user-friendly.


Better Customer Experience

When checkout is smooth, customers are happier and more likely to complete their order. Our Postcode Lookup extension removes one of the most common checkout headaches and reduces the chance of delivery issues caused by input errors.


Because the address is selected from a verified list, you can be confident that the information entered is accurate. Fewer failed deliveries means better customer satisfaction and fewer support requests.


Unlimited Lookups, Built for All Stores

Whether your shop processes five orders a week or five hundred a day, the extension includes unlimited postcode lookups. There are no usage limits or hidden costs – and it’s designed to support both OpenCart 3.x and 4.x, with full compatibility with the Journal Theme and Events System.


Just note that the extension only works with UK postcodes, and you'll need an API key to connect it to the postcode database.


Easy Installation and Updates

We’ve made setup simple. The downloaded zip includes versions for both OpenCart 3 and 4 – just choose the right one for your store. Upload it via OpenCart’s extension installer, activate it, and you're good to go.


If you're updating to a newer version, you can uninstall the old one and install the new one without losing any settings – we’ve built all our extensions to preserve your data between versions.
