I have started asking for IDs from all adults about a year ago and has really improved the quality of guests. Airbnb does not verify anything. Years ago a guy registered as "T rex" rented my house and trashed it. Because of that, I thought I needed to take matters in my own hands. It does not even have to be as dramatic as the T-rex party. I have bigger properties so I host bigger groups. I think before I started to ask for IDs, there was a feeling of anonymity by others in the group. If they broke something, no one would notice or it would be someone else's problem. The state of house at departure has improved so much.
It is an ordeal thought and many guests do not like it even though it is in the description, in the house rules and I remind them again immediately upon booking. Peoople claim no one else does this. I have personally been asked for an ID at many Airbnbs.
Do you ask for IDs and if so, how do you handle the process?
