Quick Answer: You cannot update your Aadhaar mobile number online. It has to be done in person at an Aadhaar Seva Kendra, where your fingerprint or iris confirms your identity. The fee is ₹50, you need no documents, and the new number is usually linked within a few days.
Changing your mobile number linked to Aadhaar is a process that you need to follow carefully in order to do so properly. Take note that this is one of the Aadhaar updates that you cannot do online, using your smartphone or laptop. Your mobile number is essential since it is connected to every kind of OTP, which makes the Unique Identification Authority of India (UIDAI) verify that it is you who is making the change. The manual procedure is a tutorial that explains all relevant details about fees and appointment booking process.

Can you update your Aadhaar mobile number online?
The UIDAI's official update procedure makes it clear that mobile number updates cannot be done through the myAadhaar self-service portal or the mAadhaar app. In order to make changes in your mobile number, it is mandatory to visit an Aadhaar enrolment centre.
Why must it be done in person?
This in-person rule is a security measure. Most changes in Aadhaar online, such as those regarding address, are authenticated through a one-time password sent to the verified phone number. If a person has lost the particular number and it is inaccessible, then one should visit the Aadhaar verification centre where all of his fingerprints or irises will be scanned to prove the identity.
Why do you need a mobile number linked to Aadhaar?
In the majority of instances, any proceeding that deals with Aadhaar requires that you have the registered mobile number on record.
Where is your linked mobile number used?
You must have the linked mobile number available when accessing e-Aadhaar, changing your address online, performing e-KYC for your SIM card and bank account, or verifying identity on government websites. When you lack the updated number, you will be unable to benefit from the mentioned services, which is why it is extremely important to keep it updated.
How do you update your mobile number at an Aadhaar Seva Kendra?
You need to adhere to appropriate procedures to complete the update correctly. In most cases, the process only takes very little time and is finished hassle-free.
- Visit your nearest Aadhaar Seva Kendra or Aadhaar enrolment centre, ideally with a pre-booked appointment.
- Tell the operator you want to update (or add) your mobile number, and give them your Aadhaar number.
- Provide the new mobile number you want linked. You do not need to submit any documents for this update.
- Place your finger on the scanner or complete the iris scan so the operator can verify your identity biometrically.
- Pay the ₹50 fee and collect the acknowledgement slip. It carries an Update Request Number (URN) you can use to track the status.
How do you book an Aadhaar Seva Kendra appointment online?
To reserve a time, go on your computer to the UIDAI Aadhaar Seva Kendra appointment portal. You will be allowed to visit the office without booking your appointment beforehand as well as lessen your waiting time.
- Open the UIDAI appointment booking portal.
- Choose your city and the Aadhaar Seva Kendra you want to visit.
- Select "Update Aadhaar" and pick "Mobile Number" as the field you want to change.
- Choose an available date and time slot.
- Confirm the booking and note the appointment ID. You do not need an Aadhaar-registered mobile number to book, and each person can hold up to two appointments a month.
What is the fee and how long does it take to update?
The mobile number update costs a flat ₹50, and the number is usually active within a few days.
| Item | Details |

How can you check if a mobile number is linked to your Aadhaar?
With UIDAI's free "Verify Aadhaar" feature, it is possible to find out which number is registered with Aadhaar without having to go to the centre. This service verifies whether a mobile number is registered with Aadhaar or not.
How do you check it online?
Take the following steps. Open the myAadhaar section at UIDAI's website. Here, you will find the mobile/email verification tool. Type in your Aadhaar number and mobile number for verification purposes. After that, the system will inform you whether it confirms the mobile number as required in your provider's record or not. To know about all the details regarding Aadhaar correction, including mobile number correction, check our complete Aadhaar update process guide. Jaagruk Bharat may be a private help service but, in fact, the update is done only at UIDAI centres.
What else can you do once your number is active?
As soon as the number comes into use, you can also either download the masked version of your Aadhaar for safety while sharing or even learn more about your Aadhaar's purpose as your main identification document. With an active mobile number, you can also update other Aadhaar details like your address online with our Aadhaar update service. You can look for more documents in the government ID card section.
Common mistakes to avoid
A few simple slip-ups cause most wasted trips. Keep these in mind before you go.
- Assuming you can change the number online; it always needs an in-person biometric visit.
- Paying more than ₹50; the fee is fixed, so report any overcharging to UIDAI on 1947.
- Leaving without the acknowledgement slip; you need its Update Request Number (URN) to track the change.
- Letting the new SIM lapse; keep the new number active so you continue receiving Aadhaar OTPs.
Frequently Asked Questions
Do you need any documents to update your mobile number in Aadhaar?
No documents are required to update your mobile number. Unlike a name or address change, there is no proof to submit. The operator simply verifies your identity with your fingerprint or iris scan at the Aadhaar Seva Kendra, so all you carry is yourself and the new number you want linked.
Can you update your Aadhaar mobile number using the mAadhaar app?
No. The mAadhaar app and the myAadhaar portal let you update several details, but the mobile number is not one of them. Since UIDAI requires biometric verification to change your number, this update can only be completed in person at an Aadhaar Seva Kendra, never through any app.
How do you update the mobile number for a child's Aadhaar?
A parent or guardian must take the child to an Aadhaar Seva Kendra in person. For young children, the number registered is usually the parent's mobile number. The guardian's biometrics or the child's, depending on age, are used to authenticate the request, and the same ₹50 fee applies.
What if you have lost access to the old number linked to your Aadhaar?
It does not matter. Because the update is done in person with a biometric scan, no OTP is sent to your old number. This is exactly why UIDAI keeps the mobile update offline, so people who have lost their old SIM can still regain access to their Aadhaar services.
Can someone else update your Aadhaar mobile number for you?
No. The Aadhaar holder must be present in person, because the update depends on their own fingerprint or iris scan to confirm identity. You cannot send a relative or an agent to change your number on your behalf, which protects your record from misuse.
