Is a request for my Medicare or NHS number over the phone a scam?
Yes if unsolicited. Government health agencies do not cold-call you to request your health number or personal details.
Last reviewed: 1 June 2026
Explanation
Your Medicare number (US) or NHS number (UK) is a valuable identifier used to commit healthcare fraud, file false insurance claims, or combine with other stolen details for identity theft. Scammers impersonate health agencies, insurance companies, or survey organisations and claim they need to update records, issue a new card, or check your coverage. Genuine health authorities update records through the health system when you attend an appointment — they do not call you out of the blue to ask for your number. If an unexpected caller requests your health identifier, hang up and contact the agency directly using a number from their official website.
