Ideal Postcodes provides address autocomplete and postcode lookup for your Magento address forms. We specialize in the UK addressing data, drawing the most up-to-date & accurate UK dataset from Royal Mail on a daily basis. We have over 1,000 clients that use our address validation tools to speed up checkout, increase deliverability, and ensure data quality.

This extension adds address validation including realtime address autocompletion and postcode lookup on your address forms. These tools appear on your checkout and user account pages (for billing and shipping addresses). Our address validation tools speed up the checkout process and ensure that correct addresses are collected, thereby reducing cart abandonment and ensuring deliverability.


Account & Pricing

A separate account on Ideal Postcodes is required. The account is created outside the extension installation process, via our sign up page. With an account, you can create a test and live keys to trial this extension or take it live. See our guide on account setup on how to get started. Each address search costs 2p - 2.5p + VAT. See our pricing page for more information.
