About Postcode.eu Address Validation

From the official readme · v2.9.2

Description

Postcode.eu Address validation provides address autocomplete and validation with an easy to implement API. The API offers addresses from several European countries, and more countries are constantly being added. We only work with official sources such as postal companies and governments to ensure high quality and accurate data that is up to date.

The Postcode.eu Address Validation plugin uses the Dutch Postcode API and International Address API to streamline the checkout process. By offering autocomplete suggestions for both Dutch and international addresses, it simplifies address input for customers. This functionality helps improve the accuracy of deliveries, reduce return rates due to incorrect addresses, and increase overall customer satisfaction. The result is a more efficient e-commerce operation with a higher conversion rate.

Features

  • Address Autocompletion: This feature drastically reduces the time and effort required to enter addresses, offering autofill suggestions as your customer types, applicable for both Dutch and international addresses.
  • Flexible Dutch Address Completion: Choose to autocomplete Dutch addresses based on postcode and house number, or utilize the single field input feature for an even smoother process.
  • Europe-Wide Coverage: Enjoy access to all supported countries within Europe with a single subscription, expanding the reach of your e-commerce business. View a full list of supported countries here.
  • Data Accuracy: Our plugin draws on official, up-to-date sources such as national cadastre and postal companies, ensuring all address data is precise and accurate.
  • Risk-Free Testing: Try out our API for free and without obligations, enabling you to see firsthand the benefits it can bring to your WooCommerce platform.
  • Typo Recognition: The plugin uses smart technology to detect and correct spelling errors, preventing wrong entries from being saved in your system.
  • Formatted Address Output: Choose to display an easy-to-read address for your customers, offering a clear and streamlined look instead of the standard address fields.
  • Manual Input Option: Gives customers the freedom to bypass autocomplete and manually enter their address if they prefer, ensuring the checkout process is tailored to everyone’s comfort level.
  • Privacy Protection: There are no hidden tracking elements and your data is never resold.
  • Regular Updates: Our system stays current with regular updates to supported countries, ensuring your business remains global without any extra effort.
