Is it required to check VAT numbers?
Every quarter, businesses selling digital products to EU customers have to submit an EC Sales List to their tax administration. The customer (i.e. their VAT number) quoted in the EC Sales List must be correct.
Vatstack allows you to check if the VAT number provided by your customer is registered in the relevant national database. The valid VAT number of your customer should be mentioned on your invoice.
Which countries do you currently support?
We verify VAT numbers of all businesses in the 28 EU member states

Where is the data coming from?
Our data is sourced directly from official government databases, including the VAT Information Exchange System (VIES) operated by the European Commission. It’s an electronic means of transmitting information relating to VAT registration of companies registered in the European Union.
Why should I use Vatstack?
You may, of course, validate VAT numbers against VIES directly but will quickly realize that you need to build several other functions revolving around VAT validation. Young companies underestimate the business logic and maintenance behind handling VAT and validating VAT numbers. Vatstack ships with a lot of sophisticated features to help you save time and focus on your company’s core mission.
How do you handle government service downtimes?
Government databases can experience regular downtimes for maintenance. A typical fault code during downtime is
SERVICE_UNAVAILABLE. Vatstack will gracefully accept VAT number validation requests and continue the process asynchronously in the background. Once a result is obtained, it is sent to your server via webhook events.
Simply add an API endpoint to your web application to receive webhook events. Once Vatstack has obtained a response from government databases, it will automatically post the response to that endpoint. This allows you to save your customer’s VAT number and asynchronously validate it afterwards.
Are VAT numbers required in invoices?
In the EU, stating your own and your customer’s VAT numbers in invoices are a substantive requirement for zero-rating VAT. Tax administrations may also reason that you should take reasonable steps to avoid becoming involved in any VAT fraud. You should therefore take all practical measures to verify your customers’ VAT numbers.
We’ve made it especially easy for you to validate VAT numbers automatically. A lot of business logic is already built-in and made available to you via API.
Do I need to register for VAT if my business is outside the EU?
All businesses (or individuals carrying out an economic activity) situated outside the EU selling to EU customers need to register for VAT and obtain a free VAT number. Unfortunately, there are no exceptions to these VAT obligations and no de minimis thresholds for turnover or transaction volumes.
Ignoring VAT is not a good idea. Every country in the EU enforces tax requirements themselves via audits, which can include receipts sent in by your customers (who send them in because they are entitled to tax refunds on certain goods). This is where a non-compliance could be picked up.

What are consultation numbers?
If you want to be able to prove to a tax administration of a member state that you have checked a given VAT number on a given date, and obtained a given validation reply, please keep this consultation number in your archives.
Vatstack will collect and store a consultation number and its request date on your behalf if you save your VAT number in your account settings.
What if I exceed my monthly validation limit?
You will be automatically notified if your validation requests exceed 75% and 90% of your monthly validation capacity. Exceeding the monthly allowance will not trigger any additional charges. You may upgrade your subscription plan anytime during the month to ensure that you have enough validations available. Any amount you already paid will be prorated during the upgrade.
How do the event webhooks work?
VAT validation usually takes only a few milliseconds, but depending on the availability of various government databases, it may also take longer. Vatstack will automatically handle downtimes and attempt retries for you. This means that you can provisionally obtain your customer’s VAT number and asynchronously validate it afterwards.
In your dashboard, you can set an API endpoint of your web application at which you want to receive HTTP POST requests at. These requests contain the payload of the validation result.
Can I mass-validate VAT numbers?
Yes, you can validate VAT numbers in bulk by iterating through API requests. You may, however, greatly enjoy the advantages of our mass validation solution instead.
