In [[Greece]], there are a number of national identification numbers.

* The standard identity card, which has the format X-999999 where X can be any of the 24 letters of the [[Greek alphabet]], is issued to all Greek citizens at the age of 12.
* New Greek identity cards have a number formatted like this: XX-999999 where X is a letter, whose uppercase glyph occurs in both the Greek and the Latin alphabet (ABEZHIKMNOPTYX). The letters and numbers are assigned with sequential order.
* The Tax Identity Number (AFM - ΑΦΜ - Αριθμός Φορολογικού Μητρώου - Tax Registry Number), which is used by citizens and companies for tax purposes. It has nine digits, of which the last one is a check digit.
* The Social Security Number (AMKA - Αριθμός Μητρώου Κοινωνικής Ασφάλισης) which is the work and insurance ID of every employee, pensioner and dependent member of their family in Greece. Its first six digits is the owner's date of birth in the dd/mm/yy format.<ref>{{cite web |url=http://www.amka.gr/tieinai_en.html |title=AMKA - What is the AMKA? |publisher=Amka.gr |access-date=2012-07-13 |archive-date=2012-08-26 |archive-url=https://web.archive.org/web/20120826004724/http://www.amka.gr/tieinai_en.html |url-status=live }}</ref>
