See below what Verified ID means to Airbnb.
The Verified ID badge
When you complete Verified ID, you'll earn a badge on your profile. Many hosts and guests look for this badge when deciding whether to host or stay with someone—BUT IT'S NOT AN ENDORSEMENT OR GUARENTEE OF SOMEONE'S IDENTITY (my caps)
Verified ID has misled many a host and given them a false sense of security. But, if you really think about it, you cannot verify that an ID belongs to the person who is using it on their account unless they are physically present. And even then it is not 100% guarentee as these things can be faked, not easily, but they can.
Best is, reviews, verified ID, telephone number, email, a conversation with the guest, etc. and rely on your gut! If in doubt don't accept.
