Why Aadhaar Number Validation is Important

Aadhaar card number is a unique identification card issued by the Indian government. It contains a 12-digit number that serves as a unique identifier for Indian citizens. The Aadhaar card is used for various purposes such as opening a bank account, applying for a passport, and availing of government schemes.

Aadhaar card number validation is essential because it helps ensure that the Aadhaar card number entered is correct and belongs to a valid individual. This validation process can prevent fraud and identity theft. It also helps in the smooth functioning of various government schemes and services.

Steps to Validate Aadhaar Card Number using JavaScript

Step 1: Create a Regular Expression

Regular expressions are a powerful tool used for pattern matching. We can use regular expressions to validate the Aadhaar card number entered by the user. The following regular expression can be used to validate the Aadhaar card number:

var aadhaar_regex = /^[2-9]{1}[0-9]{3}[0-9]{4}[0-9]{4}$/;

Step 2: Validate the Aadhaar Card Number

Once we have created the regular expression, we can use it to validate the Aadhaar card number entered by the user. The following code can be used to validate the Aadhaar card number:

function validateAadhaar(aadhaar) {
  if (aadhaar.match(aadhaar_regex)) {
    return true;
  } else {
    return false;

Step 3: Display Validation Result

The final step is to display the validation result to the user. We can use the following code to display the validation result:

var aadhaar = document.getElementById("aadhaar").value;
if (validateAadhaar(aadhaar)) {
  document.getElementById("result").innerHTML = "Aadhaar card number is valid";
} else {
  document.getElementById("result").innerHTML = "Invalid Aadhaar card number";
