An outdated or lost mobile number linked to your Aadhaar can block you from OTP-based services like e-KYC, PAN linking, and digital document downloads. Fortunately, Aadhaar mobile number update is a straightforward process through UIDAI, though it requires a visit to an Aadhaar center since it cannot be done fully online for security reasons.

Why Aadhaar Mobile Number Update Matters
Your Aadhaar-linked mobile number is used for OTP verification across dozens of services, from downloading your e-Aadhaar to linking PAN, opening bank accounts, and verifying identity for government schemes. If this number is outdated, lost, or was never registered, many of these services become inaccessible until it is updated.
Can Aadhaar Mobile Number Update Be Done Online?
No, not entirely. Because mobile number updates involve biometric-level identity verification, UIDAI requires this specific update to be done in person at an Aadhaar Enrolment or Update Center. However, you can book your appointment online in advance to save time.
How to Book an Aadhaar Update Appointment Online
- Visit the official UIDAI appointment portal at appointments.uidai.gov.in.
- Select your city and choose the nearest Aadhaar Seva Kendra.
- Pick an available date and time slot for your visit.
- Note down your appointment confirmation, and carry a valid ID proof to the center.
Steps to Complete Aadhaar Mobile Number Update at the Center
- Fill out the Aadhaar Update/Correction form available at the center, or download it in advance from the UIDAI website.
- Provide your Aadhaar number and the new mobile number you want linked.
- Complete biometric verification (fingerprint or iris scan) to confirm your identity.
- Pay the update fee, which is currently Rs. 50 for a mobile number update.
- Collect your Update Request Number (URN) receipt to track the status.
How Long Does the Update Take?
Mobile number updates are typically processed within a few hours to a few days after your center visit. You can check the status anytime using your URN on the UIDAI portal under Aadhaar Update Status.
Alternative: Updating Through Aadhaar Seva Kendra Without an Appointment
While booking an appointment online is recommended to avoid long waiting times, most Aadhaar Seva Kendras also accept walk-in visitors on a first-come, first-served basis, though wait times can be significantly longer during peak hours.
What Happens If You Don’t Update Your Mobile Number
Without an active linked mobile number, you will not be able to use OTP-based services such as instant e-PAN download, DigiLocker document verification, or online Aadhaar corrections. If you also need to update your address or fix an error in your name or date of birth, our guide on Aadhaar correction online covers those changes, and many of them can be completed at the same center visit. Once your number is updated, you can immediately use it to complete an Aadhaar address update online if needed.
Frequently Asked Questions
Can I update my Aadhaar mobile number using OTP on an old number?
No. Since the whole point of this update is that you no longer have access to the old number, UIDAI requires an in-person biometric verification instead of OTP for this specific change.
How much does Aadhaar mobile number update cost?
The standard fee is Rs. 50, payable at the Aadhaar center during your visit.
Can I update my mobile number and address at the same time?
Yes, you can request multiple updates, such as mobile number and address, in a single visit to the Aadhaar Seva Kendra, though each type of update may be processed separately.
For more details, see the official UIDAI website.
Documents to Carry for Aadhaar Mobile Number Update
- Your original Aadhaar card or a printed copy of your e-Aadhaar.
- One valid government-issued photo ID as additional proof, such as a PAN card, passport, or driving licence.
- The new mobile number you want to link, since you will need to confirm it at the center.
Tips for a Smooth Aadhaar Mobile Number Update Visit
Book your appointment during off-peak hours, typically mid-morning on weekdays, to minimize waiting time. Double-check the new mobile number you provide on the form before submitting it, since a typo means repeating the entire process and paying the fee again. Keep your URN receipt safe until the update is confirmed, since you will need it to track status or raise a complaint if there is a delay.
