Aadhaar Card

How To Change Mobile Number In Aadhaar Card

Your Aadhaar card is perhaps the most important document in your wallet today. It is linked to your bank account, your PAN card and your various government subsidies. Because almost every online service requires an OTP (One-Time Password) for verification, having an active and updated mobile number linked to your Aadhaar is not just a convenience, it is a necessity. If you have lost your old SIM card or switched to a new number you must update it in the official records to keep your digital life running smoothly.

In 2026 the process of changing your mobile number remains a secure biometric-based procedure. While you can update your address online, changing a mobile number requires you to prove who you are using your fingerprints or iris scan. This is done to prevent fraudsters from stealing your identity by simply changing your number online. Whether you want to book an appointment from home or walk into a nearby center here is how you can ensure your new number is correctly registered.

The 2026 Update Process: Offline is Mandatory

As of early 2026 the UIDAI (Unique Identification Authority of India) requires you to visit a physical center for mobile number updates. This is because your mobile number is the key to your identity and changing it requires high-level security verification (biometrics).

Method 1: Booking an Appointment Online (To Save Time)

  1. Visit the Portal: Go to the official UIDAI website ([suspicious link removed]).
  2. Book Appointment: Click on  My Aadhaar and select  Book an Appointment.
  3. Choose Location: Select your city or a nearby Aadhaar Seva Kendra (ASK).
  4. Enter Details: Provide your current mobile number (for the appointment OTP) and solve the captcha.
  5. Select Service: Choose  Mobile Number Update from the list of services.
  6. Pick a Slot: Choose a date and time that suits you. Print or save the appointment slip.

Method 2: The Walk-in Process

If you cannot book an appointment you can simply find a nearby Aadhaar Enrolment Centre located in many banks, post offices and government buildings.

  1. Locate Center: Use the  Locate an Enrolment Centre tool on the UIDAI website.
  2. Fill the Form: Ask for the Aadhaar Update/Correction Form at the center.
  3. Enter New Number: Write your new mobile number clearly in the form. You do not need to provide your old mobile number.
  4. Biometric Verification: The operator will take your fingerprints or scan your eyes to verify that you are the real owner of the Aadhaar.
  5. Pay the Fee: A nominal fee is charged for this service.

Why You Can't Do It Only Online?

Many websites might claim you can change your mobile number entirely from home. This is a myth. Because the mobile number is used to send OTPs for other changes, allowing a mobile change via OTP creates a loop that hackers could exploit. By requiring you to physically show up and provide your fingerprints, UIDAI ensures that only you can change your digital key.

Frequently Asked Questions (FAQs)

Do I need my old mobile number to update to a new one?

No. If you have lost your old SIM you don't need it. Your identity is verified using your biometrics (fingerprints/eyes) at the center.

Can I update my mobile number through the mAadhaar app

Yes, UIDAI allows residents to book an appointment online for Aadhaar services at select centres.

Is there a limit to how many times I can change my number?

Technically no. You can change your number as many times as you need but you must pay the ₹50 fee each time.

Can I change my mobile number at a Post Office?

Yes! Most Post Offices and many Nationalized Banks (like SBI or PNB) have dedicated Aadhaar desks for these updates.

What is the URN?

The Update Request Number (URN) is a 14-digit number printed on the acknowledgement slip you get after your visit. You can use this to track your update status online.

Does my Aadhaar number change after a mobile update?

No. Your 12-digit Aadhaar number remains the same for life. Only the linked details (like mobile or address) change.
No. Only one mobile number can be primary and registered to receive OTPs and official communications at a time.

What if my fingerprints are not matching at the center?

If your fingerprints are worn out (common for senior citizens or laborers) the operator can use an Iris Scan (eyes) or Face Authentication to verify you.

Can I update my child's mobile number?

Yes. For children below 5 years the parent's biometrics are used. For children above 5 their own fingerprints are required.

How do I verify if my new number is finally linked?

Visit the UIDAI website and use the  Verify Email/Mobile Number tool. Enter your Aadhaar and new number. If it's linked it will say the mobile number you entered is already verified.
