Whether the clinic publishes its operating licence and the dentists working there together with their professional licence numbers. A verified “not published” is recorded as a red flag; data we have not checked yet is shown as unverified and carries no penalty.
Clinic operating licence: Registered Vertragszahnarztpraxis — KZV Berlin Zahnarztsuche (practice: 'MVZ Zahnzentrum Ku'damm', Kurfürstendamm 33, 10719 Berlin - Charlottenburg) (KZV Berlin (scope both, open, name search); searched all 6 named team members, all matched exactly on address with clinics.json. Registry lists the practice under the name 'MVZ Zahnzentrum Ku'damm' rather than the 'Dental21 Kudamm' brand name, and shows a different phone (322923120) than clinics.json (030 81455310) — same address, likely a rebrand/legal-name difference, not a mismatch of premises. 2026-08-25.)
