Quick Answer: You can now update your Aadhaar mobile number in two ways in India in 2026: online through UIDAI's official Aadhaar app, which confirms it's you with face authentication, or in person at an Aadhaar Seva Kendra with a fingerprint or iris scan. UIDAI's fee for a mobile number update is ₹75, and no documents are needed. If you never registered a mobile number with Aadhaar, you must visit a centre.
Changing the mobile number linked to Aadhaar used to mean a trip to an enrolment centre. That has changed. UIDAI's new Aadhaar app lists Mobile Number Update among its services, so most people can do it from their phone. Your mobile number matters because it receives every Aadhaar OTP, and UIDAI uses it to confirm that it is really you making a change. This guide covers both routes, the fee and how to book a centre appointment if you need one.
Overview: Aadhaar mobile number update at a glance
| Detail | What to know |
|---|---|
| Online route | UIDAI's Aadhaar app (Android and iOS), with face authentication |
| In-person route | Aadhaar Seva Kendra or Aadhaar enrolment centre, with fingerprint or iris |
| Fee | ₹75 (free if done together with a biometric update) |
| Documents needed | None |
| Never registered a mobile? | You must visit a centre in person |
| Update time | Usually a few days (UIDAI allows up to 90 days) |
| Tracking | "Track my request" in the app, or the URN on your centre slip |
Can you update your Aadhaar mobile number online?
Yes. UIDAI's Aadhaar app offers Mobile Number Update along with address update, e-Aadhaar download and request tracking. The app verifies you with a live face scan instead of a fingerprint, so you don't need to visit a centre.
Who still has to visit a centre?
UIDAI says that if you did not register a mobile number when you enrolled for Aadhaar, you must visit an enrolment centre to get one added. If face authentication doesn't work for you in the app, or you don't have a smartphone, the centre route is the alternative.
How do you update your mobile number in the Aadhaar app?
The app route takes a few minutes if your face authentication goes through.
- Download the official Aadhaar app published by UIDAI from the Play Store or App Store.
- Register: choose a language, enter your Aadhaar number, accept the terms, choose the SIM card, complete face authentication and set a 6-digit PIN.
- Open the services list and select Mobile Number Update.
- Enter the new mobile number and complete the on-screen verification steps.
- Finish any payment step shown and note your request number. You can follow it under "Track my request".
How do you update your mobile number at an Aadhaar Seva Kendra?
The centre route works for everyone, including people who never linked a number.
- 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 ₹75 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, use the UIDAI Aadhaar Seva Kendra appointment portal. A booking is optional, but it cuts your waiting time at the centre.
- 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?
A mobile number update is a demographic update, and UIDAI's update charges set it at ₹75 when done on its own. It is free if you do it at the same time as a biometric update.
| Item | Details |
|---|---|
| Update fee | ₹75 (free alongside a biometric update) |
| Overcharging | Report any demand above the official fee to UIDAI on 1947 |
| Update time | Commonly a few working days; UIDAI permits up to 90 days |
| Proof of request | Request number in the app, or the URN on your centre slip |

How can you check if a mobile number is linked to your Aadhaar?
UIDAI's free "Verify mobile number" check tells you whether a number is registered with your Aadhaar, without a visit to the centre.
How do you check it online?
Open the myAadhaar section on UIDAI's website and find the mobile/email verification tool. Enter your Aadhaar number and the mobile number you want to check. The system then tells you whether that number matches UIDAI's records. For other Aadhaar corrections, see our complete Aadhaar update process guide. Jaagruk Bharat is a private help service; the update itself is always done by UIDAI, in its app or at its centres.
What else can you do once your number is active?
Once the new number is active, you can download the masked version of your Aadhaar to share safely. You can also update other details, like your address, with our Aadhaar update service.

Common mistakes to avoid
A few simple slip-ups cause most failed requests and wasted trips.
- Using an unofficial app; download only the Aadhaar app published by UIDAI.
- Paying more than the official ₹75; report any overcharging to UIDAI on 1947.
- Losing your request number or URN; you need it to track the change.
- Letting the new SIM lapse; keep the new number active so you continue receiving Aadhaar OTPs.
