TAJszám

TAJ-szám, short for Társadalombiztosítási azonosító jel, is a unique identifier used in Hungary’s health and social security system to identify individuals with public health coverage. It is issued to citizens and residents who are covered by the public health insurance and is required when accessing medical services, receiving prescriptions, and submitting health-insurance claims. The TAJ number links a person to their health- and social-security records, including insurance contributions and entitlements such as sickness benefits and pensions. Healthcare providers, pharmacies, and the national health insurance administration use the number to verify coverage and process payments. The TAJ number is a confidential personal data item and should be shared only with authorized health- and social-security institutions.

Who gets a TAJ number: Hungarian citizens and residents who participate in the public health-insurance system receive one. For newborns, a TAJ number is assigned when they are registered with health care services; new residents or people joining the system later are issued a TAJ number upon enrollment.

Privacy and scope: The TAJ number is a private identifier, not a public ID. It is used strictly for health- and social-security related administrative purposes.

Relation to tax ID: The TAJ number is separate from the adóazonosító jel (tax identification number); they serve different public administrations.

Obtaining or updating: To obtain a TAJ number or update personal details, contact the local government office or the health-insurance fund as instructed by Hungarian authorities.
