Offshore company bank is asking for tax residency and TIN

We have a Seychelles company with a HK bank account.
Now the bank is asking us information of the tax residency and provide the TIN number.

Since this company has no tax residency and they require this information what should we fill in? If we indicate the tax residency is in HK there will be no exchange of information but still a TIN will have to be provided (which is HK BR number, which this company doesnt have).

Any ideas?
