Postcode check and address validation for WooCommerce
Let customers enter only their postcode and house number in your WooCommerce checkout. The plugin fills in the street and city automatically with up-to-date address data from Nederland Postcode API. That means fewer incorrect orders and a faster checkout.

Why address validation in your WooCommerce webshop?
Fewer failed deliveries
A typo in the street name or a wrong house number costs you shipping fees and an unhappy customer. With a verified address, the parcel arrives the first time.
Faster checkout
Customers fill in two fields instead of four. Especially on mobile, that saves typing and keeps customers from dropping off before they pay.
Clean customer data
Addresses end up in WooCommerce in the same format. Useful for your shipping labels, your accounting and integrations with other systems.

Frequently asked questions about the WooCommerce plugin
- Can I also use address validation in forms on my WordPress site?
- Yes. Postcode Checkout also has a plugin for Contact Form 7, so you can validate addresses in contact and quote forms as well. Both plugins can use the same Nederland Postcode API subscription.
- What does the WooCommerce plugin cost?
- You pay for two things: a subscription at Nederland Postcode API for the address data, from €59.99 per year for an unlimited number of websites, and a license at Postcode Checkout for the WooCommerce plugin itself. You can find the current license prices on the Postcode Checkout website.
- Can I test the WooCommerce plugin for free?
- Yes. With a free account at Nederland Postcode API you get a test API key that works for postcodes starting with 1012, 1015 or 1118. Postcode Checkout offers a free trial period for the WooCommerce plugin. That way you can test everything before you pay.
- Can I use one subscription for multiple websites?
- Your Nederland Postcode API subscription covers an unlimited number of websites and webshops, including client projects. The Postcode Checkout license depends on the number of websites you install the WooCommerce plugin on.
- What happens when I reach my limit?
- You receive an email at 80%, 90% and 100% of your monthly limit. At 100%, new requests are rejected until the start of next month. You never pay extra for requests above your limit.
