Endpoints

The API is available as GET and POST endpoint.

    -d '{ "vatId": "ATU16370905" }'

Response

Both endpoints return a application/json response. For example, the response for the VAT number of the Austrian Red Cross looks like this:

{
  "valid": true,
  "name": "Österreichisches Rotes Kreuz",
  "address": "Wiedner Hauptstraße 32, AT-1040 Wien",
  "countryCode": "AT"
}

The value valid indicates whether the respective entity is listed in the associated state database and marked as active. If the format of the VAT number is not correct, an error is returned. More about this in the section Possible errors.

The name and address values are optional. If available, the official name and address where the company is registered will be returned here.

As countryCode the respective country with which the VAT number is associated is returned as ISO 3166-1 alpha-2 code. Caution: The Greek VAT number starts with EL. However, the official ISO 3166-1 country code GR is returned.
