VAT number invalid


I just got an email saying that I must go to Finance > Vat details and add my vat number. My vat number was there originally, but was "lost" after some changes in Booking.

When I click YES, I have a VAT number, and add my VAT number, it says it's not valid. I typed my VAT number here and it works perfectly.

Specifically it's EL (Greek VAT number), and the VAT number is ***. I've tried to put as input:



*** Everything says to be invalid... I have to do this until 30/5/2020 and no one picks up the phone on booking!


Thanks in advance,


Sirena Residen…

Same issue here.

The VAT was provided (as it shows in your invoices you are sending).

VIES validates it but your system NOT! Now I have to engage with the support... fix your bugs and stop wasting our time!

I received the same email.

When entering my VAT number, in any format, it shows invalid. 

Please advise asap.

Same problem for us as well although our VAT is valid in VIES 

Nefeli Apartments

I have the same problem, I received an email asking me to change the VAT number and when I go to the specific link to change it, it's always invalid.

I tried typing in 3 different formats:

  1. just the numbers xxxxxxxxx,
  2. with ELxxxxxxxxx and
  3. with EL xxxxxxxxx (with space)

but it's always invalid. I checked with the link provided and I could verify it without any issues.

  1. Is this some kind of scam?
  2. If not, do we need to put the VAT in a specific format?

Please advise.

Next following the email that I received, it's in Greek.

Αγαπητέ συνεργάτη,
Πρόσφατα πραγματοποιήσαμε κάποιες εσωτερικές αλλαγές στον τρόπο με τον οποίο μπορείτε να προσθέτετε και να προσαρμόζετε τον αριθμό ΦΠΑ της εταιρείας σας. Μπορείτε τώρα να διαχειριστείτε τα στοιχεία ΦΠΑ σας μέσω της Καρτέλας Οικονομικά > στοιχεία ΦΠΑ.
Συμπληρώστε τα στοιχεία ΦΠΑ


Κατά τη διαδικασία αυτή πραγματοποιήσαμε έναν έλεγχο επαλήθευσης του αριθμού ΦΠΑ που είχαμε καταχωρημένο για το κατάλυμά σας μέσω του ιστοχώρου της Ευρωπαϊκής Επιτροπής (Σύστημα ανταλλαγής πληροφοριών για το φόρο προστιθέμενης αξίας (VIES) Επαλήθευση αριθ. ΦΠΑ) και δυστυχώς το αποτέλεσμα ήταν ότι ο αριθμός σας είναι «μη έγκυρος». Για αυτόν τον λόγο, θα αφαιρέσουμε τον μη έγκυρο αριθμό από το σύστημά μας και δεν θα εμφανίζεται πλέον στο τιμολόγιό σας από τον 01-06-2020.


Χρειάζεται να κάνω κάτι εγώ;


Σας παρακαλούμε να ενημερώσετε το προφίλ σας με έναν έγκυρο αριθμό ΦΠΑ έως τις 30-05-2020, προκειμένου να εμφανιστεί στο τιμολόγιο. Εάν δεν έχετε αριθμό ΦΠΑ, χρησιμοποιήστε το αναπτυσσόμενο μενού και επιλέξτε έναν έγκυρο επιχειρηματικό λόγο. Με εκτίμηση, Η ομάδα της

I just received a reply to my support ticket:

Dear Partner, Thank you for contacting us regarding you being unable to save your VAT number. We do have a system technical issue with the VAT number page and are looking into it. There is no work round at the moment. Should you have any further questions, please do not hesitate to contact us. -- *** Partner Support Team

Hello everyone! Thanks for flagging this problem. From what I managed to find out, it looks like some partners are facing this kind of difficulty. The good thing is that the product team is fully aware of the problem, and that our partners mention it in the Partner Community. So right now the team is working on the ways to solve it. It will probably take time.

So please let me know in the comments if you still see this problem after a few days.

This problem is still happening for me here in the UK.  It says to input before 31 August 2020 and if I have "any questions, we recommend that you contact your tax advisor or accountant." but its no problem on our side of things its's issue

The recent news I can share is that the developers team fixed the bug for the Greek market. And the product team is making sure our connection to VIES works smoothly. The final testing maybe will take a little more time.
