by Aadhaar mobile number update is one of the most important changes you can make, since your registered mobile number controls OTP verification for banking, government services, and identity checks. If your old number is lost, deactivated, or simply outdated, this guide walks you through the correct Aadhaar mobile number update process step by step.
Unlike many other Aadhaar updates, this one cannot be completed entirely online, and knowing that upfront saves a lot of wasted time.
Why You Cannot Update Your Mobile Number Online
UIDAI requires biometric verification for any Aadhaar mobile number update, specifically because this field controls OTP-based authentication for so many other services. Allowing it to be changed purely online would create a serious security gap, so the rule applies to every applicant, with no exceptions for lost or inactive numbers.
How to Update Mobile Number in Aadhaar: Step-by-Step
1. Locate Your Nearest Aadhaar Seva Kendra
Use the UIDAI locator tool to find the nearest Aadhaar Seva Kendra or authorized enrollment center. Some centers require a prior appointment booked through the myAadhaar portal, so check before you go.
2. Carry Your Aadhaar Number or Card
You do not need extensive documentation for a mobile number update alone. Bringing your Aadhaar number, or the physical card if you have it, is generally enough since biometric verification confirms your identity at the center.
3. Fill Out the Update Request Form
At the center, you will fill out a demographic update form and select “mobile number update” as the field you want changed. Double-check the new number before submitting, since a typo means repeating the entire visit.
4. Complete Biometric Verification
A fingerprint or iris scan confirms your identity in place of the OTP that would normally be sent to a registered number. This is the step that makes in-person verification unavoidable.
5. Pay the Update Fee
The standard fee for a demographic update, including a mobile number change, is approximately ₹50. Keep the payment receipt along with your acknowledgment slip.
6. Save Your Update Request Number (URN)
You will receive a URN on your acknowledgment slip. Use this to track your update status online through the myAadhaar portal without needing to visit the center again.
How Long Does the Update Take?
Most mobile number updates in Aadhaar process within 2 to 7 working days, though some cases take a few additional weeks depending on the center’s workload. You will typically receive an SMS confirmation to your newly updated number once the change is complete. Planning ahead for this Aadhaar mobile number update timeline helps you avoid last-minute stress before a deadline.
Why an Outdated Mobile Number Causes Problems
An outdated or incorrect mobile number in Aadhaar creates problems well beyond Aadhaar itself. Many banks, insurance providers, and government portals rely on Aadhaar-linked OTP verification for identity checks, meaning an old number can quietly lock you out of services you did not even realize depended on it. A few common consequences include:
- Failed OTP verification when linking Aadhaar to a new bank account or updating KYC
- Being unable to download your e-Aadhaar using the OTP-based option
- Missed alerts about unauthorized changes to your own Aadhaar record
- Delays in applying for government subsidies or welfare schemes tied to Aadhaar verification
Because of these downstream effects, it is worth treating a mobile number update as a priority rather than something to put off indefinitely.
What If You Cannot Access Your Old Number?
This is exactly the situation the in-person process is designed for. Since biometric verification replaces the OTP step entirely, you can update your mobile number in Aadhaar even if your previous number is permanently lost, deactivated, or was never truly yours to begin with.
If you are managing a wider range of Aadhaar tasks, such as downloading your e-Aadhaar or updating your address alongside your mobile number, it is worth reviewing the complete guide to downloading, updating, and managing your Aadhaar for the full picture beyond just the mobile number field.
If you are enrolling for Aadhaar for the first time rather than updating an existing one, the process is different, and the step-by-step guide for new Aadhaar enrollment covers that separately.
Common Problems and Fixes
My update request was rejected: This usually happens due to a mismatch in biometric data or an incomplete form. Visit the center again and ask staff to verify the exact reason before resubmitting. A rejected Aadhaar mobile number update almost always gets resolved on the second attempt once the mismatch is fixed.
I have not received SMS confirmation after a week: Use your URN on the myAadhaar portal to check your status directly rather than waiting indefinitely, since processing times vary by center.
Can someone else update my mobile number for me: No. Biometric verification means you must be physically present, and updates cannot be completed by a family member or representative on your behalf.
Frequently Asked Questions
Can I update my Aadhaar mobile number online through the myAadhaar portal?
No. Mobile number updates require in-person biometric verification at an Aadhaar Seva Kendra and cannot be completed online for security reasons.
What documents do I need to update my mobile number in Aadhaar?
No additional documents are typically required beyond your Aadhaar number, since biometric verification at the center confirms your identity.
How much does it cost to update mobile number in Aadhaar?
The standard fee for a demographic update, including a mobile number change, is approximately ₹50, payable directly at the center.
Updating your mobile number in Aadhaar takes a single in-person visit, a small fee, and a few working days of processing. It may feel like an extra step compared to fully online updates, but the biometric requirement exists specifically to protect your identity from unauthorized changes.
