Greece has undergone a shift on its ID cards with the introduction of mandatory personal numbers which will be used instead of their Tax ID or Greek social security number when interacting with public sector services.

The change is a move to modernising how Greek ID holders engage with public services as well as providing an extra layer of protection for their personal data, as reported by To Vima.

The number itself is a 12-digit alphanumeric code unique to each citizen that is printed on the back of the new digital ID card and stored in an embedded chip.

The personal number replaces older identifiers like the Tax ID (AFM) and Social Security (AMKA) numbers.

Unlike Tax ID and Social Security numbers, personal numbers are not linked to biometric data and is designed with privacy and encryption in mind.

The personal number is now required for all newly issued IDs, while older IDs will include it upon renewal.

It is noted that existing IDs remain valid until their expiration.

The update aids in streamlining communication with public authorities, eliminating the need for multiple documents and reducing data leaks.

Citizens can obtain the number online if they already have the new 10-year card, while new applicants will need to secure it before visiting a police station.
