Step-by-Step Guide

Updating your mobile number in Aadhaar can be accomplished through two primary methods: online via the UIDAI official portal or in-person at an Aadhaar enrollment center. While the online method is faster and more convenient for most users, the in-person option is essential for those without internet access or who face technical difficulties. Below is a detailed, step-by-step breakdown of both approaches.

Method 1: Update Mobile Number Online

Updating your mobile number online is the most efficient method, provided you have access to your registered mobile number or email address and can receive OTPs. This process requires you to be logged into your Aadhaar profile and have your biometric details accessible for authentication.

1. Visit the official UIDAI website at https://myaadhaar.uidai.gov.in.
2. Click on the Update Mobile Number option under the Aadhaar Services section. If you dont see it immediately, navigate to My Aadhaar > Update Demographic Data > Mobile Number.
3. Enter your 12-digit Aadhaar number and click Send OTP.
4. Wait for the One-Time Password (OTP) to be delivered to your currently registered mobile number. If you no longer have access to this number, you cannot proceed with the online method and must visit an enrollment center.
5. Once you receive the OTP, enter it into the designated field and click Verify.
6. You will now be prompted to enter your new mobile number. Type it carefully and re-enter it in the confirmation box to avoid typos.
7. Click Submit. You will be asked to authenticate your identity using biometrics this requires access to a fingerprint scanner or iris scanner connected to a device.
8. If you are using a personal computer, you may need to visit a nearby Aadhaar enrollment center or authorized service point that offers biometric authentication services. Some private kiosks and bank branches provide this facility for a nominal fee.
9. After successful biometric verification, your request is submitted. You will receive a confirmation message on your new mobile number and an email to your registered email address.
10. Within 24 to 72 hours, your updated mobile number will reflect in the UIDAI database. You can verify the update by visiting the Check Aadhaar Status page on the UIDAI portal.

Method 2: Update Mobile Number at an Enrollment Center

If you do not have access to your old registered mobile number or encounter technical issues with the online portal, visiting an Aadhaar enrollment center is your best option. These centers are widely available across India and are often located in post offices, banks, and government service hubs.

1. Locate the nearest Aadhaar enrollment center. You can search using the UIDAI portals Find Enrollment Center tool by entering your state, district, and pin code.
2. Carry your original Aadhaar card or Aadhaar number. If you dont have the physical card, your 12-digit Aadhaar number printed on any official correspondence is sufficient.
3. Bring a valid photo ID proof (PAN card, drivers license, passport, voter ID) and address proof if requested. Although mobile updates do not require address changes, carrying these documents ensures smooth processing.
4. Fill out the Aadhaar Update Form (Form No. 002) available at the center. Clearly write your new mobile number in the designated field. Double-check the digits before submission.
5. Submit the form along with your Aadhaar number and ID proof to the operator.
6. Provide your biometric details fingerprints and/or iris scan as required for authentication. This step is mandatory and ensures the update is authorized by you.
7. After submission, you will receive an Update Request Number (URN). Save this number as it allows you to track the status of your request.
8. Wait for 7 to 10 business days for the update to be processed. You will receive an SMS on your new mobile number once the update is complete.
9. Verify the update by visiting the UIDAI website and selecting Verify Mobile Number under Aadhaar Services.

Important Notes

Regardless of the method chosen, remember the following:

• You can update your mobile number only once every 30 days. Multiple requests within this window will be rejected.
• You cannot update your mobile number if your Aadhaar is locked or blocked. Ensure your Aadhaar status is active before proceeding.
• Only one mobile number can be linked to a single Aadhaar. Previous numbers are automatically overwritten.
• There is no fee for updating your mobile number. Any request for payment at an enrollment center is unauthorized and should be reported.
• Always use the official UIDAI portal or government-authorized centers. Avoid third-party websites claiming to offer Aadhaar updates for a fee.

Best Practices

To ensure a smooth, secure, and error-free mobile number update process, follow these industry-tested best practices. These guidelines are designed to prevent common pitfalls, reduce processing delays, and safeguard your personal data.

1. Verify Your Current Mobile Status Before Updating

Before initiating any update, confirm whether your current mobile number is still active and linked to your Aadhaar. Visit the UIDAI portal and use the Verify Mobile Number feature. If you receive a confirmation that your number is active, you can proceed with the online update. If not, prepare for an in-person visit.

2. Use a Reliable and Active Mobile Number

Choose a mobile number that you plan to use long-term. Avoid temporary or burner numbers. Since your Aadhaar-linked mobile receives OTPs for critical services like bank transactions, e-KYC, and government subsidies, an inactive or frequently changed number can disrupt access to essential services.

3. Avoid Typographical Errors

A single digit error in your mobile number can render the update useless. Always type the number twice during entry. If updating online, copy and paste from a saved contact if possible. At enrollment centers, ask the operator to read back the number before final submission.

4. Save Your Update Request Number (URN)

Whether you update online or offline, always note down your URN. This 14-digit number is your proof of request and allows you to track the status. Keep it in a secure digital or physical location. If your update doesnt reflect within 10 days, youll need this number to follow up.

5. Do Not Share OTPs or Biometric Details

Never share your OTP or biometric authentication details with anyone, even if they claim to be from UIDAI or a government agency. UIDAI will never ask for your OTP over the phone or via email. Sharing this information can lead to identity theft and unauthorized access to your accounts.

6. Update Other Linked Services Simultaneously

Once your mobile number is updated in Aadhaar, immediately update it in all linked platforms: bank accounts, UPI apps, income tax portal, insurance policies, and telecom providers. Many services rely on Aadhaar for authentication, and a mismatch can cause service interruptions.

7. Keep a Digital and Physical Copy of Confirmation

After successful update, download and save the confirmation SMS and email. Print a copy and store it with your important documents. This serves as proof of compliance in case of disputes or audits.

8. Monitor for Fraudulent Activity

After updating your mobile number, monitor your bank statements, UPI transactions, and SMS alerts for any unusual activity. If you notice unauthorized access, immediately report it to your bank and file a complaint with UIDAIs grievance portal.

9. Update for Family Members Separately

If youre updating mobile numbers for multiple family members, do so individually. Each Aadhaar holder must complete their own update process with their own biometrics. Do not attempt to update others details using your credentials this is a violation of UIDAI guidelines.

10. Use Official Channels Only

Always use the UIDAI website (https://uidai.gov.in) or authorized enrollment centers. Avoid third-party apps, WhatsApp services, or unofficial websites. These may collect your data or charge hidden fees. The official portal is free, secure, and encrypted.

Tools and Resources
