Postcode check and address validation for Magento 2
With the Magento 2 extension by Postcode Checkout, customers only enter their postcode and house number. The street and city are filled in automatically, so you process fewer incorrect addresses and your checkout gets faster.

Why address validation in your Magento webshop?
Reliable order data
With many orders per day, the number of incorrect addresses adds up quickly. Verified addresses go straight to your fulfilment or carrier without manual correction.
Smoother checkout
Less typing means fewer abandoned orders, on both desktop and mobile.
Predictable costs
Even with a lot of traffic you pay a fixed price per year for the address data, without fees per lookup. You get a notification before you reach your limit.
