What to disclose to a host about myself, when they ask?

[Jennifer378]

Hi all!  is it normal for a host to ask for your nationality and passport number in order to 'complete a booking'?  I am new to Air B&B and was asked this and wasn't sure.  thanks.

Depending where you are booking, there are places that require hosts to provide this information to their regulators, so it is not outside the realm of possible things a host could ask for.  Certain hosts also like to reqest this information so they can verify the person who actually shows up for the booking is the same person who booked.
