What is this for?

  • Check the given Turkish ID number to see if it's a valid Turkish ID number
  • Generate new and valid Turkish ID numbers as much as you want
  • Find your relatives' (including siblings) Turkish ID numbers by whether they're younger or older than you
  • Find the missing part (rightmost two digits) of a deficient Turkish ID number with 9 (leftmost) digits

*TC Kimlik No = Turkish ID (Number) = TC ID number

Nedir? (Turkish)

Yerel ve uluslararası tüm projelerde kullanılabilmesi için İngilizce yazılmıştır. TC kimlik numaralarını doğrulamak veya algoritmik test odaklı çeşitli ihtiyaçlar nedeniyle geçerli TC kimlik numaraları oluşturmak, akrabaların ve kardeşlerin TC kimlik numaralarını bulmak veya son iki hanesi eksik olan TC kimlik numarasını geri kalanıyla birlikte tahmin etmek için kullanılabilir. Yeni TC kimlik numaralarının oluşturulmak istenmesi aşağıdakilerden dolayı olabilir:

  • Merak
  • Algoritmanın test edilmesi
  • Çeşitli sorgulama veya yazım denetimi işlevleri için hazır bekletilmek üzere geçerli TC kimlik numaraları barındıran bir havuz oluşturulması
  • TC kimlik numaraları arasındaki farkın ve sistemin gözetlenmesi

How to use this?

Note: 12345678901 is a placeholder for your possible TC ID number(s).

To validate the given TC ID number:

python main.py -v 12345678901

or

python main.py --validate 12345678901

To generate new TC ID numbers:

Let's say you want to generate 10 new TC ID numbers by starting from the TC ID number 12345678901. So you can use the commands below:

python main.py -g 10 -s 12345678901

or

python main.py --generate 10 --start-from 12345678901

To find relatives (including siblings):

If you want to find your relatives' TC ID numbers, you can use this command. You need to use -r parameter with the -o (--older) or -y (--younger), by giving a limit, then a sample TC ID number to get the relatives according to. You can combine -r with -o or -y parameters, for instance -or or -yr.

For example, in order to find three younger relatives according to the TC ID number 12345678901, use:

python main.py -yr 3 -s 12345678901

It could also be written like this so:

python main.py -r 3 --younger -s 12345678901

or like this:

python main.py --younger --relatives 3 --start-from 12345678901

It's your choice.

To guess the missing part of a TC ID number with 9 leftmost digits:

python main.py -f 123456789

or

python main.py --guess 123456789

Algorithm:

(Rule 1) To find the tenth digit:

n10 = ((n1+n3+n5+n7+n9)*7-(n2+n4+n6+n8)) mod 10

(Rule 2) To find the eleventh digit:

n11 = (n1+n2+..+n10) mod 10

To check a TC ID number in order to be sure it's valid:

  1. The first digit should be greater than 0.
  2. The length should be 11 digits.
  3. Check the tenth digit (n10) by the rule 1.
  4. Check the eleventh digit (n11) by the rule 2.

To find the relatives:

Take the first 9 leftmost digits of the TC ID number, then split it into two pieces from the fifth digit (including the fifth digit).

If you want to get an older relative:

Then you should add 3 to the first part and subtract 1 from the second part. The last thing you should do is to guess the tenth and eleventh digits of the TC ID number according to the rule 1 and the rule 2.

If you want to get a younger relative:

Then you should subtract 3 from the first part and add 1 to the second part. The last thing you should do is to guess the tenth and eleventh digits of the TC ID number according to the rule 1 and the rule 2.

Disclaimer:

Its some or all functions may or may not work for someone randomly, for newborns or for one who's younger than a person born or married after 2000s (It's my guess but logically it might be right. After all TC ID numbers had been distributed, it was easy to know that a couple with a few or one child(ren) will have their own TC ID numbers related to the each other's TC ID number according to the relatives algorithm).
