The VAT-ID is not being recognized.
The VAT-ID is verified live by contacting the VIES servers which are only available during 5:00 am and 11:00 pm.
Please make sure that the company information data is entered in the online form exactly as it has been registered.
(enter VAT-ID here without the prefix, it’s in the drop down. In our iFixit EU Store enter with prefix but without space in between)
Use your company name (including company type if mentioned), VAT-ID and city as listed on that page.
If you are unsure about the characters (for example it can be difficult to transfer Greek to Latin characters) try online translation services.
