False booking is the house term for a reservation that was never real: a fabricated identity, someone else's number, a prank, or an address where nobody planned to answer.
A cancellation is a genuine booking that ended. A false booking was never genuine to begin with. That distinction decides how the house responds.
The house keeps the record. The identifiers, meaning the number, the name used and the address given, go to other reputable Amsterdam houses, so that the next office to receive the same request recognises it. Where appropriate, the relevant authorities are informed.
The roster is forty-five women, each crossing the city by herself to buildings she has never entered, often late, sometimes at four in the morning. A fabricated address costs a therapist an hour of travel at the very least. At worst it sends her somewhere she should not be. Sharing identifiers between houses is the one protection that works before a door opens.
Nothing new. Book under your own name, from your own number, for an address where you will actually be. A delayed train or a mistyped room number, sorted out in the thread, is not a false booking, and honest clients are entirely unaffected by any of this. Nor is a newcomer treated as a suspect: the half asked on a first booking reflects committed cost, not doubt about the person. The booking page lays out each step, and WhatsApp booking explains why the written thread matters.
