Airbnb now hides any 4 digit numbers! They hide key codes, the year, they even hide links to Chamber of Commerce so guests can check on COVID related closures when we send confirmation letters! We change our key codes after each renter ( our cleaners take care of it), and , we refuse to allow airbnb to have this code, as they say we can add it to our "amenity" section, and them "they" give it to of renter 3 days before the reservation. Boycott? We should, but we need their visibility. They need to learn, it is we, the owners, who made their business, and without us, they would not be!!!!
