On Airbnb, you can receive a booking request from a guest who doesn't have their ID verified. If this is something you require from all your guests before they book, lack of ID verification will prevent your guest from completing their reservation.
It is possible to enable a notification whenever ID verification is required for one of your guests, to make sure that you can provide them with needed assistance.
To enable notifications:
Go to Settings.
Click on Preferences.
Click on Notifications on the sidebar.
Use a toggle to activate a feature Receive notification emails when guest ID verification is required.
Don't forget to Save changes.
