Identifications for Different Purposes
If you are planning to live in Greece, there are three official ID numbers you may need to navigate daily life. Each serves a different purpose: the AMKA links you to healthcare and social security, the AFM handles taxes and financial matters, and the Personal Number is the unique identifier you use whenever you interact with any government service, including the police, social security, or other state agencies.
Understanding the difference between them will help you interact with government offices, access services, and live in Greece smoothly. Consider them as three distinct tools: one for your health, one for your finances, and one for identification by the authorities.
The AMKA Social Security Number (Αριθμός Μητρώου Κοινωνικής Ασφάλισης / ΑΜΚΑ) is connected to healthcare and social security. If you want to work legally in Greece or access public healthcare, you will need an AMKA. Every time you visit a doctor, use a pharmacy, or need treatment at a hospital, your AMKA will identify you in the social security system and ensure that your contributions and entitlements are properly recorded. For foreigners who plan to work or receive medical services, obtaining an AMKA is essential.

The AFM Tax Identification Number (Αριθμός Φορολογικού Μητρώου / ΑΦΜ) is a completely different type of number. While the AMKA deals with health and social security, the AFM is all about taxes and financial matters. Every legal financial transaction in Greece—whether opening a bank account, signing a rental contract, paying utility bills, or even starting a business—requires an AFM. Even if you are not working, having an AFM is practically mandatory for living in Greece, because it allows you to interact with the financial and legal system without problems.
The Personal Number (Προσωπικός Αριθμός) serves an administrative purpose. Unlike the AMKA or AFM, it is separate from healthcare and taxes. Instead, it identifies you in municipal and local government records. Foreigners often receive a Personal Number when registering their residence at a local town hall or when interacting with municipal services. It is mostly used for administrative tracking, permits, and official documentation, ensuring that local authorities can accurately identify residents.
Key Differences to Remember
AMKA = healthcare and social security
AFM = taxes and financial transactions
Personal Number = to interact with any public authority
By understanding the purpose of each number and where to get it, you will be able to navigate Greek bureaucracy much more easily. Start with the AMKA if you need healthcare or plan to work, then the AFM for financial matters, and finally the Personal Number for municipal registration. Having all three ensures you can live in Greece legally, access services, and avoid unnecessary problems.
