AMKA (https://www.amka.gr/) is the Greek Social Security Number.
According to http:https://www.ggka.gr/er_amka_main1.htm (frameset http:https://www.ggka.gr/er_amka.htm):
The Greek Social Security Number (AMKA) is an 11-digit numeric string.
It is consisted of 3 parts:
- the first part is 6-digit and indicates the date of birth (DDMMYY)
- the second part is 4-digit and indicates the serial number in the National Registry within the same date of birth. It is an odd number for men and even number for women
- the third part is 1 digit (control character).
REMARK: DDMMYY
is dmy
in php (see http:https://php.net/manual/en/datetime.createfromformat.php)
d
Day of the month, 2 digits with leading zerosm
Numeric representation of a month, with leading zerosy
A two digit representation of a year (which is assumed to be in the range 1970-2069, inclusive)
Probably, "two digit representation of a year" was not a good idea. Moreover, it is a reason why this class does not check if first 6 digits represent a future date (just exactly because this is happens for all AMKA before 1970).
