Epic Games does not validate VAT (Value Added Tax ID) numbers. When adding a VAT number to your account, it is processed through the official system.
If you receive an error that your VAT number is invalid, please visit this website to verify the status. You can visit the FAQ and Help sections of the website for more information. VAT country must match the country of your Epic Games account.
If you verify that the VAT number is valid, please Contact Us for further assistance.
