secret hidden behind ktp

For those of you who have aged 17 years or more would you have had or at least have known what it is KTP (Identity Card). But perhaps most of you do not know if just from the numbers contained in your ID card, can show exactly where you live, your gender and date of your birth. Once again I emphasize only the number without seeing the other information contained on your ID card.

ID number, it is realized or not, a number that is so important for the citizens of Indonesia. Maybe your ID card number is more important than your bank account number. Each form must be filled there by masyasarat, there is usually a box where the charging ID number, whether it's a form for a replacement ATM card, open a bank account, make a driver's license or other form. In short, the ID number is very important to us all as citizens of Indonesia.

ID number that we have had a 16 digit number is composed as follows:

PPKKCC.HHBBTT.RRRR

ID Number Description

PP is the number code of the Province where the issuance of ID cards.
KK is the code number Regency / Municipality where the issuance of ID cards.
CC is the district code number where the issuance of ID cards.

HH is today's date of birth of owner ID card.
MM is the month of birth of owner ID card.
TT is the year of birth of owner ID card.

RRRR is the registration number listed when filing the manufacture ID (Registry Number)

Phone area code either Province, Regency / City and District, each taken from a number area code is based on the classification system from the Central Statistics Agency (BPS). So suppose, if you apply for ID cards in the district of Menteng, Central Jakarta. Then the first 6 digits on your ID card number is 317 302. Where the 31 indicates the area code of DKI Jakarta, then show the code number 73 Central Jakarta City area and number 02 shows the code Menteng subdistrict.

The next 6 digits are marked HHBBTT is the date, month and year of birth of the holder. For 2-digit date of birth of HH indicating there is little special treatment. Where if the holder is a woman then the date of birth will be added to the 40. Reason number 40 is added to give a clear distinction. With the number of days in a month the maximum amount to 31, then taken a bigger number than it is to provide a clear distinction. Suppose if coupled with the number 20, a woman who was born on the 5th if added 20 will be 25 to be confused with a man who was born on the 25th.

While the figures are taken for the TT is last 2 digits of birth year ID card holders. So when the holder was born on August 17, 1975 HHBBTT then six digits with the number 170 875 will be written when he was male and 570 875 when she is a woman.

Last 4 digits marked RRRR is the registration number. This is the number listed when filing making ID cards. Numbers is what keeps no two people who lived in the same area and have sex and same birth date has the same ID number. So if for example after the A registered, it turns out no one else in the district which turned out to have the date, month and year are identical to the A and the same sex then he will have a different registration number to distinguish it from the A.
