We recently lost a week long reservation from a guest because of this new, unannounced policy regarding verified IDs. The guest (a senior) submitted an inquiry and had numerous positive reviews and other information, but no verified ID. Normally we require verified IDs, but this person explained their fear of uploading their information online and talked about breaches and scams.
As a compromise, we agreed to accept the reservation based on their reviews, but stated that they wouldn't receive admittance to the rental until we met them personally at the door and viewed their IDs. Guest was just fine with this.
Guest attempted to proceed with booking once we approved them, but Airbnb system wouldn't allow them to do so. After trying various tweaks on our end, we involved Customer Service. They told guest that there was a new requirement for guests to have verified IDs and they would have to comply in order to complete booking.
Guest was too scare to do this and we ended up with no one that week. How frustrating!
