Host or guest?
The check reports an account, not its type.
Can I find someone's listing or reviews?
No. The result contains no profile, listing, review or address, and it should not be used to identify a person. Treat it as an audience count: the number belongs to an Airbnb account, or it does not.
Why might a regular traveller read as not registered?
Airbnb accepts more than one way of signing up, and the phone number on the account may be an older one or not the one you hold. A no means no account was found for this number, not that the person has never stayed in an Airbnb.
Can this find every host in one city?
No. The result names neither a role nor a place. If hosts are your market, begin with a list already about property, such as local landlords or short-let managers, and use the check to decide who is worth calling first.
