Validation message
Explanation
A Greek seller should state exactly one VAT ID: the prefix EL followed by a 9-digit Greek tax number with a valid check digit. This check fails if it is missing, given more than once, or built differently.
How to fix
Ask the seller for a corrected invoice that states its VAT ID as EL followed by 9 digits.
