If you receive an error message
The VAT ID you enter is validated against the EU's VIES system (VAT Information Exchange System). If you receive an error message "This VAT identification number is invalid" it means the VAT ID is not approved for cross-border transactions within the EU. You need to have the VAT ID approved by the relevant authorities before tracezilla can validate it and save it with your billing information.
You can check the status of your VAT ID directly in the European Commission's VAT number validation tool.
