Being frank, the majority of the population just understands that their mobile number was not connected to Aadhaar only when they require an OTP and it does not come. Did you lose your old SIM, or have switched operators, or just never got a number in the first place, this is one of those scenarios that can silently drag a bank operation, an income tax filing or a DigiLocker log in.
The good news? It is not difficult to update mobile number in Aadhaar. However, there is a fly in the ointment that most of the online guides fade away, you cannot do this one hundred percent online at home. This is a mandatory biometric authentication and as such, a physical visit to an Aadhaar Enrolment Centre is always involved.
This how-to will take you step by step through what to do, how to save time by making your appointment online, what to bring, what to expect at the centre, how much and how to look at whether the update was successful.
The Real Reason Your Mobile Number is Connected to Aadhaar
It is important to explain why this is really more important than most people expect before the steps.
The India core digital identity infrastructure is Aadhaar. The number of eligible residents enrolled is over a billion and the system has now been at the heart of all things between subsidies and Jan Dhan accounts to submitting ITR and seeking passports. Almost all of the government services in which OTP-based authentication is needed require that your mobile number is properly registered in the UIDAI database.
This is where it becomes useful:
- DigiLocker only provides login OTP, but only to the Aadhaar-registered number.
- Aadhaar-linked mobile is needed to do an e-verification of income tax e-filing.
- UPI and AEPS (Aadhaar Enabled Payment System) depends on authenticated Aadhaar information.
- Aadhaar OTP authentication is frequently used to identify investors in mutual funds and insurance.
- Google Pay, PhonePe, and other UPI applications require Aadhaar verification when enrolling.
In case you are using a SIM number which you do not own, all your services would be inaccessible via OTP. It is a little administration job that has quite big implications whenever it is late.
How to update Mobile Number in Aadhaar Online at Home?
It is the top-ranking question searched on Google concerning this subject matter – and the response must be obvious.
Yes you cannot change your mobile number in Aadhaar at all at home. This particular update requires biometric authentication (fingerprints and/or iris scan) by UIDAI and this implies that you have to be physically present in an Aadhaar Enrolment Centre.
Online you can do:
- Make a booking at an Aadhaar Seva Kendra (ASK).
- Request is initiated using the new Aadhaar App (in some instances, needs biometric completion at a centre)
- Find the closest enrollment centre.
- Monitor your request to update status.
The online booking system is truly helpful, it is not necessary to stand in a line and waste hours, just to find a slot for an appointment. Consider it as a web-based aspect of a process that remains shortened with a personal visit.

Hint: UIDAI will permit a limit of 4 appointments per month using one mobile number. The appointment is free of charge at all.
Carry With You to the Aadhaar Enrolment Centre
The paper work to update Aadhar mobile numbers is less than some people anticipate. Here are a few items you should bring along:
Your Aadhaar card (physical card or e-Aadhaar printout which is downloaded)
Your appointment slip (printed or phone)
The new mobile number you would prefer to get registered, ensure you have this SIM active and you have it when you visit on that day.
There is no need to bring along with you the old registered mobile phone or show ownership to the old number. This is significant to individuals who have lost or completely replaced the old SIM.
How It is done at the Aadhaar Enrolment Centre
The visit is fast, less than 15-20 minutes, in case you have made an appointment.
- Present your appointment slip at the reception/ token register.
- Send a message to the operator saying that you would like to change your mobile number.
- Complete the Aadhaar Update/Correction Form – the operator will tend to help.
- Offer biometrics – fingerprints and/or iris scan to view.
- Pay fee at the cash desk or through online payment (see on fees below)
- Take acknowledgement slip with the Update Request Number (URN) – your tracking number.
Your request will also be signed-off by the operator biometrically and this will provide an additional verification to the process.
Mobile Number updating in Aadhaar
This is a little yet compulsory payment. According to the UIDAI regulation, which will be in effect between October 2025 and September 2028:
Service
One can either pay in cash at the cash counter of the centre or by digital payment where possible. Keep the receipt.
No limit on the number of updates to your mobile number over your lifetime – but each time, you will pay ₹50.
Procedure 2: Walk In
In case of inconvenience with online booking, you just have to directly walk into any of the authorised Aadhaar Enrolment Centres. The centre process is the same – fill in, biometrics, pay the fee, pick up your URN.
The sole disadvantage is that it might have wait time especially during the rush centres within cities. The holders of appointments are normally processed in advance of walk-ins.
To find the closest centre, visit the UIDAI Bhuvan Aadhaar Portal bhuvan.nrsc.gov.in/aadhaar/ – you can search by either PIN code, district or state.
Method 3: With the help of the New Aadhaar App
UIDAI has also published a specific Aadhaar application that enables its users to change some of its updates in a more transparent and easier manner. To update mobile numbers, in particular:
- On the official Aadhaar app, download and open it.
- Use an Aadhaar number as a log-in.
- Click on Update Aadhaar Details on the home screen.
- Tap the mobile number update button.
- Input in the new number and enter.
Note: The application requires secure UIDAI authentication systems and they may still need to undergo biometric authentication at a local Aadhaar centre. The application can be most helpful to kick-start the request and be instructed through the necessary documents or steps.
