Explanation
For a Greek seller, the first part of the invoice number must be a valid Greek tax number (AFM): exactly 9 digits with a correct check digit. It must also match the VAT ID of the seller or of its tax representative, without the EL prefix.
How to fix
Ask the seller for a corrected invoice whose number starts with its 9-digit tax number, the same one that follows EL in its VAT ID.
