A tool for validate Turkish Identification Number

You can install this component via npm or yarn

npm install istckimlik
yarn add istckimlik

const { isTCKimlik } = require('istckimlik');

// Pass a number to validate
const isValid = isTCKimlik(48265878901);
console.log(isValid); // returns true or false

// The function accepts a number and returns a boolean

• Input must be a number type
• Returns true if the ID is valid, false otherwise
