Why Updating Your Mobile Number on Aadhaar is Crucial in 2026
Keeping your mobile number current on your Aadhaar card is more important than ever, given the increasing digitisation of services across India. An outdated number can lead to significant inconvenience and even security risks, hindering your ability to conduct everyday tasks. For instance, Vimala, an e-commerce seller in Mumbai, relies on her Aadhaar-linked mobile for GST filings and bank account access.
The Unique Identification Authority of India (UIDAI) mandates that your registered mobile number is the primary contact for all Aadhaar-related communications and verifications. This ensures that only you can authorise transactions or access sensitive information linked to your unique identity. Without an updated number, you might miss out on critical alerts or face issues with service authentication.
- Essential for OTP verification across banking, government, and digital payment platforms.
- Required for accessing various Aadhaar-linked services, including PAN, provident fund, and subsidies.
- Facilitates future Aadhaar detail updates, such as changes to address or name, which often need an OTP.
- Protects against identity fraud by ensuring only you receive verification codes for your Aadhaar.
- Necessary for receiving benefits from government schemes like PM-KISAN or LPG subsidies.
Quick Context: Aadhaar OTP Dependency
In 2026, most government and financial services, including opening bank accounts, filing taxes, and accessing welfare schemes, require an Aadhaar-linked mobile number for OTP-based authentication.
Process to Update Mobile Number on Aadhaar: Online Appointment Booking
While you cannot directly update your mobile number on Aadhaar entirely online due to biometric authentication requirements, you can book an appointment at an Aadhaar Enrolment Centre. This online booking feature saves you time and helps manage crowds at service centres. It ensures a smoother experience when you visit in person.
The UIDAI website offers a user-friendly portal to locate nearby centres and schedule your visit at a convenient time. This step is highly recommended to avoid long waiting periods, especially in busy urban centres like Mumbai. Remember, the actual update requires your physical presence for biometric verification.
Step 1: Visit the UIDAI Appointment Portal. Access the official UIDAI website (uidai.gov.in) and navigate to the ‘Book an Appointment’ section. You will find a clear option to proceed with scheduling your visit.
Step 2: Select Your Location and Service. Choose your city or a specific Aadhaar Seva Kendra (ASK) from the dropdown menu, then select ‘Mobile Number Update’ as the service you require. Enter your current Aadhaar number and other necessary personal details as prompted.
Step 3: Schedule Your Visit. Review the available dates and time slots, then select the one that best suits your schedule for visiting the centre. Confirm your appointment details and make a note of the booking reference number provided.
Step 4: Attend the Centre with Required Documents. Go to the Aadhaar Enrolment Centre at your scheduled date and time, carrying your Aadhaar card and any other identity proof. Provide your new mobile number to the operator and complete the mandatory biometric authentication (fingerprints and iris scan).
Step 5: Pay the Update Fee. A nominal fee of ₹50 (including GST) is charged for updating your mobile number on Aadhaar, as per UIDAI guidelines (2026). You can pay this fee at the centre using cash or digital payment methods.
Step 6: Collect the Acknowledgment Slip. Upon successful completion of the process, you will receive an acknowledgment slip containing a 14-digit Update Request Number (URN). Keep this slip safe as you will need the URN to track the status of your update.

Pro Tip: Prepare for Your Visit
Before visiting the Aadhaar centre, ensure you have your existing Aadhaar card and the new mobile number you wish to link. Carrying a valid proof of identity, such as a PAN card or passport, can also be helpful, although not always strictly required for mobile number updates.
Updating Your Mobile Number at an Aadhaar Enrolment Centre
If online appointment booking is not feasible, you can always visit an Aadhaar Enrolment Centre directly to update your mobile number. This walk-in option is available at all authorised centres across India, ensuring accessibility for everyone. The process at the centre remains largely the same, focusing on biometric verification.
Finding your nearest Aadhaar centre is straightforward through the UIDAI website’s ‘Locate an Enrolment Centre’ feature. These centres are typically located in post offices, banks, and designated government offices. It is advisable to check the operating hours before your visit.
Step 1: Locate Your Nearest Aadhaar Centre. Use the UIDAI website (uidai.gov.in) to find the Aadhaar Enrolment Centre closest to your location by entering your PIN code or district. Note down the address and operating hours.
Step 2: Visit the Centre with Your Aadhaar Card. Carry your physical Aadhaar card to the chosen centre. You do not need to bring any other document specifically for a mobile number update, as identity is verified biometrically.
Step 3: Fill Out the Aadhaar Update Form. At the centre, request an Aadhaar Update/Correction Form from the operator. Fill in your new mobile number clearly in the designated field and ensure all other details are accurate.
Step 4: Complete Biometric Authentication. Submit the filled form to the operator, who will then capture your fingerprints and iris scans for biometric verification. This step confirms your identity and authorises the mobile number change.
Step 5: Pay the Applicable Fee. Pay the ₹50 update fee (including GST) for the mobile number change. The operator will provide a receipt for your payment.
Step 6: Collect Your Acknowledgment Slip. Receive an acknowledgment slip with your URN after the process is completed. This URN is vital for tracking the status of your mobile number update.

Common Confusion: Online vs. Offline Update
Many believe they can update their Aadhaar mobile number completely online using an OTP. As of 2026, direct online mobile number updates are not possible. You must visit an Aadhaar Enrolment Centre for mandatory biometric authentication, even if you book an appointment online.
How to Check Your Aadhaar Mobile Number Update Status
After submitting your request to update your mobile number, it is natural to want to track its progress. The UIDAI provides a dedicated online facility to check the status of your update request using the URN you received. This ensures transparency and keeps you informed throughout the process.
Typically, a mobile number update on Aadhaar takes between 2 to 5 working days to process, though it can sometimes extend to 10 days. Vimala often advises her e-commerce colleagues to check their status regularly to ensure their services are not interrupted. Once updated, your new mobile number will be linked to your Aadhaar.
Step 1: Access the UIDAI Website. Go to the official UIDAI portal (uidai.gov.in) and look for the ‘Check Aadhaar Update Status’ option. This link is usually found under the ‘My Aadhaar’ section.
Step 2: Enter Your URN and Aadhaar Number. Enter the 14-digit Update Request Number (URN) from your acknowledgment slip into the specified field. You will also need to enter your 12-digit Aadhaar number.
Step 3: Complete the Captcha Verification. Solve the simple captcha challenge displayed on the screen to prove you are not a robot. This is a standard security measure to prevent automated queries.
Step 4: Check the Status. Click on the ‘Get Status’ button. The system will then display the current status of your mobile number update request. It could show ‘In Process’, ‘Completed’, or ‘Rejected’.

The Update Request Number (URN) is your unique identifier for tracking any Aadhaar update request. Always keep your acknowledgment slip safe until your update is confirmed.
Verifying Your Updated Mobile Number on Aadhaar

Step 1: Visit the UIDAI Verification Page. Navigate to the UIDAI website (uidai.gov.in) and find the ‘Verify Email/Mobile Number’ option under the ‘My Aadhaar’ section. This is designed for checking both email and mobile linkages.
Step 2: Enter Your Aadhaar and New Mobile Number. Enter your 12-digit Aadhaar number into the first field. In the second field, enter the new mobile number that you recently updated.
Step 3: Complete Captcha and Send OTP. Solve the security captcha and then click on the ‘Send OTP’ button. An OTP will be dispatched to the mobile number you just entered.
Step 4: Enter OTP and Verify. Enter the OTP you received on your mobile phone into the designated field on the website. Click ‘Verify’. If the numbers match, a confirmation message will appear, stating that your mobile number is successfully verified with your Aadhaar.
