How we check licences

We check each clinic in the official registers of its country. Where a country licenses clinics as facilities, we look for the facility; where it does not, we check the lead doctor's registration instead.

What the licence states mean

  • Licence confirmed: found in the official register named, with a matching name and address, on the date shown.
  • Doctor registration confirmed: no facility licence is required or publicly listed in this country; the lead doctor's registration was confirmed in the official register on the date shown.
  • Not yet checked: listed from public information; no register check recorded yet.

A clinic's own statement about its licence, or a regulator's logo on its website, never counts as confirmation. Each clinic report shows its licence state, the register, the date of the check and, in some countries, the licence number.

How a match is made

For a facility licence, we look for the clinic in a register its country uses for facilities, and the name and address on the register must match the clinic. For a doctor's registration, we look for the named doctor in the country's doctor register. Each check records the register, the licence type, the name and number as the register shows them, a link to the entry (or to the search page when entries have no fixed address), the date and how the match was made.

Some registers can be read by our research tools; others block automated reading, use a captcha or work only in a browser app. We never try to get round such a block: an analyst checks those registers by hand, and until then the clinic shows "Not yet checked". When we search a register and cannot find a doctor the clinic names, the record goes to an analyst and is held off the guide until the check is done.

Why some countries rely on doctor registration

Countries license clinics in different ways. In some, every health centre needs a facility licence, so only a facility entry gives "Licence confirmed"; a doctor's registration there earns the doctor-registration points in the score but does not replace the facility licence. In others, a doctor's own practice needs no facility licence, or there is no public list of licensed clinics. There, the lead doctor's entry in the official doctor register is the check, and it gives "Doctor registration confirmed". The section for each country below says which applies.

Country by country

United States

Most states do not license a doctor's office or a longevity clinic as a facility. Where no facility licence applies, the lead doctor's state licence is the check. Florida health care clinics can be confirmed in the AHCA list. FSMB DocInfo and the NPI registry are not used as confirmation.

United Kingdom

Clinics that carry out regulated activities in England, such as diagnostic and screening procedures or treatment of disease, must register with the CQC. Where a clinic's services fall outside CQC scope, the lead doctor's GMC registration is the check.

Switzerland

We found no public list of cantonal facility licences, so the lead doctor's MedReg entry, with a practice authorisation in the clinic's canton, is the check.

Germany

Private hospitals need a concession under §30 Gewerbeordnung, but there is no central public register of them. Outpatient practices need no facility licence, so the lead doctor's chamber entry is the check.

Austria

Hospitals and stand-alone outpatient clinics (selbstständige Ambulatorien) need a state permit and appear in the ministry list. A doctor's own practice needs none, so the Ärzteliste entry is the check.

Spain

Every health centre in Spain needs authorisation from its autonomous community, so the facility must be found in REGCESS or the regional register. Registers for Andalusia, Valencia and Catalonia are to be added when the first clinic there is checked.

Indonesia

Clinics need a facility licence (Klinik Pratama or Klinik Utama). Facility checks follow the Bali Clinic Guide method: registry entry or licence document matched to the registry code.

Thailand

Private clinics and hospitals need a licence under the Medical Facility Act, so the facility must be found in the DHSS register.

Singapore

Outpatient medical services need a Healthcare Services Act licence, so the clinic must be found in MOH's list of licensed providers.

Australia

Only private hospitals and day procedure centres hold a state facility licence. For other clinics, the lead doctor's Ahpra registration is the check.

United Arab Emirates

Every private health facility needs a licence from the health authority of its emirate: DHA in Dubai, DHCR in Dubai Healthcare City, DoH in Abu Dhabi and MOHAP in the northern emirates. The facility must be found in that authority's register. Dubai Law No. 17 of 2026 adds a Dubai Longevity Authority permit for longevity activities; we found no permit rules or public list on 21 Oct 2026.

Mexico

Hospitals, surgical units, X-ray imaging and stem cell or regenerative medicine establishments need a COFEPRIS sanitary licence; other clinics file a notice of operation. We found no public list of either, so the lead doctor's cédula profesional in the Registro Nacional de Profesionistas is the check.

The re-check cycle

Licences and registrations are checked again every four months. A check older than 120 days still shows, with a CHECK DUE tag next to its date. A clinic stays ranked only while its licence or registration was confirmed within the last 12 months; after that, it stays listed with the reason "Licence or registration last confirmed more than 12 months ago; a new check is due."

Clinics can send their register name and number, or their doctors', to clinics@longevityclinicsguide.com. We check what they send in the register itself before we change the record.
