Using the European Commission EU VAT Number validation API with Node.js

You may know of the VIES site where you can manually validate EU VAT numbers but did you know that the European Commission also has an API for programmatically doing this?1

So that’s the good news.

The bad news is that it’s SOAP.

I’ll wait until you’re done retching… ok, feeling better? Let’s move on.


Here’s how you consume it in Node.js:

  1. Install the soap package:

npm install soap
  1. Create the web service by consuming the WSDL file and calling the right method:2

import soap from 'soap'
const wsdl = ''

const client = await soap.createClientAsync(wsdl)
const result = await client.checkVatAsync({
  countryCode: 'EE',
  vatNumber: '100244258'


And that’s all there is to it.

Enjoy! 3
