Why should you use a postal code API for your WooCommerce webshop? Because with such an API you make it a lot easier for your visitors / customers.

WooCommerce Postcode Checker

Another plugin you can use is the WooCommerce Postcode Checker. This is a plugin that works perfectly with WooCommerce.

  • Filling in extra data: after the visitor has entered the correct postal code, additional data is automatically filled in. This is for the street and the place fields.

An important advantage of this plugin is that the plugin uses multiple postal code databases. Some of these databases are free, but for some you have to pay an x amount. How this works exactly depends on the number of ‘calls’ per month. A really popular webshop would have to pay money for this plugin.
