Turkish ID 🔖

Status Coverage Downloads Dependencies Maintainability Version Docs

This gem provides methods to validate Turkish Identification Numbers.

Installation

Add this line to your application's Gemfile:

gem 'turkish_id'

And then execute:

$ bundle

Or install it yourself as:

$ gem install turkish_id

Usage

Validating ID Numbers

Create a new instance:

identity_number = TurkishId.new(10000000146)

Use valid? method to check validity:

identity_number.valid?  #=> true

Querying the Government Registry

Create a new instance:

identity_number = TurkishId.new(10000000146)

Use registered? method to query the government registry:

identity_number.registered?("Ahmet", "Yılmaz", 1987)  #=> false

There is also a convenience method called not_in_registry? which is the logical equivalent of !registered?.

Use foreigner_registered? method to query the foreigner registry:

identity_number.foreigner_registered?("Yukihiro", "Matsumoto", 14, 4, 1965)  #=> false

There is also a convenience method called foreigner_not_in_registry? which is the logical equivalent of !foreigner_registered?.

Generating Relatives

You can generate ID numbers for your younger or elder relatives.

me = TurkishId.new(10000000146)

Calling younger_relative or elder_relative will return an Enumerable class.

me.elder_relative  #=> #<Enumerator:0x00007f9e629032d0>

You can perform standard Enumerable operations on it.

me.elder_relative.first  #=> 10003000082
3.times do
 puts me.elder_relative.next
end

#=> 10035998982
#=> 10005999902
#=> 10008999848
me.elder_relative.take(5)  #=> [10003000082, 10005999902, 10008999848, 10011999774, 10014999610]

And so on.

CLI (Command Line Interface)

You can use the CLI for quick lookups:

$ turkish_id 10000000078  #=> true

The executable terminates with a proper exit status:

$ turkish_id 10000000078  #=> true
$ echo $?                 #=> 0
$ turkish_id 10000000079  #=> false
$ echo $?                 #=> 1

Run turkish_id --help to learn more:

Usage
  turkish_id ID_NUMBER [GIVEN_NAME SURNAME YEAR_OF_BIRTH]

Description
  turkish_id validates Turkish identity numbers.
  Only providing ID_NUMBER performs numerical validation (offline).
  Providing all arguments will query government registry (online).

Examples
  turkish_id 10000000078
  turkish_id 10000000146 Ahmet Yılmaz 1984
  turkish_id 10005999902 "Ayşe Nur" Yılmaz 1996

Anatomy of the Turkish ID Number

The Turkish Identification Number consists of 11 digits.

There are three conditions for a valid identification number:

  1. d1 > 0
  2. d10 == ((d1 + d3 + d5 + d7 + d9) * 7 - (d2 + d4 + d6 + d8)) mod 10
  3. d11 == (d1 + d2 + d3 + d4 + d5 + d6 + d8 + d9 + d10) mod 10

Where dn refers to the n-th digit of the identification number.

Remember that a valid identification number does not imply the existence of an ID. It could only be used as a preliminary check e.g. before querying a government website. This is very similar to credit card validation.
