Information When you buy a train ticket, you will be asked to name 16 digits of the Citizen Identity Number (NIK) in the e-ID card. But do you know the 16 digit number is not just any number? There is a secret code that makes it different from other people's e-ID.
For example from the picture above, 31-02-01-44-03-91-0312, how to know the meaning is as follows.
31: Refers to the province code. According to Permendagri No. 39 of 2015, there are currently 34 provinces registered in the Republic of Indonesia.
02: City / district code, you can see your city code on this page http://www.kemendagri.go.id/pages/data-world
01: District code, each sub-district has different code. So when you make e-ID card is always recommended to come directly to the respective district office.
44: Date of birth. Well, here is the difference between male and female code. Code for men is the date of birth 01-31. while for women are different again, the date of birth plus 40, will be 41-71. So if you're a girl born on the 12th then the code is 40 + 12 that is 52.
03: Referring to the month again, 01 to January and beyond 12 for December.
91: Year of birth, written the last two numbers. Like if you were born in 1991 then only 91 written.
0312: Computerized number, this is a random number that is already set by the computer so as not to twin with the others. But usually for the head of the family will be written xx01, for the first child xx02, so on.
Usually on your ID card there is a 16 digit number of Population Identity Number (NIK) in e-ID card.
