Problem by upgrading from Basic to "Pro"


Sorry, my English is not perfect....

During the process for upgrading the Zoom -Tarif from Basic to Pro it is necessary to notice a certain "tax-number".

(in Germany it is the so-called "USt-Nr." (similar to VAT)).

I notice my right number, but always the answer is: " number not valid".

(but no writing-mistake).

What could be the problem?

(very little company)

The "chat" from Zoom was not able to help (10 trials).

Have anybody an idea, where could be the key?

Many thanks.
