VAT Number Validations

Highly-secured, real-time EU VAT number validation that allows you to check the VAT number for a business. It's helpful when you sell to business customer and do not need to add VAT.

VatZen is Deprecated since January 2022 and API server will be shut down soon!
We obtain company's informations directly from different official sources, such as EU commissions DB and local countries databases. All subscription plans are allowed to perform real-time VAT ID validations and company information lookups through the validate and validations API endpoints.
Hot and Cold Validations
At VatZen we have a concept of 2 validations types: Hot and Cold.
Cold validation works in fire and forget way. Meaning that you simply call our endpoint and we return you the data, which is never stored afterwards.
Hot validation is different from the cold one in the way that all the requests you make has id's assigned and stored in our DB. And you can always fetch this validations (fetch them all of fetch by id).
Cold validations are performed via validate endpoint, end hot validation use validations CRUD endpoint. You can get more details below.
Using Requester Data
When validating VAT number, EU commission database can return you reference id, which you can then use in your reports or during the audit process. In order to obtain this reference number, you have to provide requested VAT number, meaning the number of your company.
In order to do that, simply go to VatZen's dashboard and fill the VAT Number option on the settings page: https://dashboard.vatzen.com/settings​
Consultation number is used  if you want to be able to prove to a Tax Administration of a Member State that you have checked a given VAT number at a given time, and obtained a given validation reply.
Validation Entity
