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)
- Visit the Portal: Go to the official UIDAI website ([suspicious link removed]).
- Book Appointment: Click on My Aadhaar and select Book an Appointment.
- Choose Location: Select your city or a nearby Aadhaar Seva Kendra (ASK).
- Enter Details: Provide your current mobile number (for the appointment OTP) and solve the captcha.
- Select Service: Choose Mobile Number Update from the list of services.
- 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.
- Locate Center: Use the Locate an Enrolment Centre tool on the UIDAI website.
- Fill the Form: Ask for the Aadhaar Update/Correction Form at the center.
- Enter New Number: Write your new mobile number clearly in the form. You do not need to provide your old mobile number.
- Biometric Verification: The operator will take your fingerprints or scan your eyes to verify that you are the real owner of the Aadhaar.
- 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.
