VAT number verification

The system checks your customers' VAT numbers and company data against an official register (NAV, VIES or the country's own register) and flags any difference from the stored data or an invalid VAT number.

When does the check run?

• Automatically every week, for all customers.
• By hand: on a customer's Verification tab, for the customers selected in the list (Verify selected), or for everyone (Check all).

Where does the official data come from?

• Hungary: NAV – name, address, postal code, city and branch offices. This needs your company's own NAV access and the Validate Hungarian tax numbers via NAV setting (Team Settings → Integrations); without them the system uses VIES.
• Romania, Czech Republic, Poland, Denmark: the country's official tax or business register.
• Norway, United Kingdom: the country's official register.
• Other EU countries: VIES – company name and address. For Germany and Spain, VIES only says whether the VAT number is valid and returns no address; for Cyprus, France, Lithuania and Malta the address may be incomplete.
• Customers in other countries are not checked.

Statuses

• Verified – the stored data matches the official data.
• Data changed – some data (or, for Hungarian companies, the list of branch offices) differs; you decide what to keep.
• Invalid VAT – the VAT number is not in the register.
• Not verified – no check has run yet, or the customer cannot be checked.

Resolving differences

On the customer's Verification tab you can take over the official data with one click. In the review opened by the Fix button in the list, you choose field by field between the current and the official value. If you keep your own value, the system remembers it and does not flag the same difference again.

Differences only in upper/lower case or spacing are settled automatically; you do not need to do anything about them.
