How to Update Mobile in Aadhaar

Updating your mobile number in your Aadhaar card is a critical step to ensure seamless access to government services, financial transactions, and digital identity verification. As Aadhaar serves as the primary identity document for over 1.3 billion residents in India, maintaining accurate and up-to-date contact information is not just a convenience—it’s a necessity. Whether you’ve changed your phone number due to relocation, service provider switch, or loss of a device, failing to update your mobile number can result in missed OTPs, delayed subsidies, failed KYC verifications, and restricted access to critical services like income tax filing, bank account linking, and welfare schemes.

The process of updating your mobile number in Aadhaar is straightforward, secure, and designed to be accessible to all citizens. The Unique Identification Authority of India (UIDAI) offers multiple channels for this update, including in-person enrollment centers and online self-service portals. This guide provides a comprehensive, step-by-step walkthrough of the entire process, along with best practices, essential tools, real-world examples, and answers to frequently asked questions—all tailored to help you complete the update accurately and efficiently.

Step-by-Step Guide

Updating your mobile number in Aadhaar can be done either through an Aadhaar Enrollment Center or via the UIDAI online portal. While both methods are valid, the in-person method is recommended for first-time updates or if you encounter issues with authentication. Below is a detailed breakdown of each approach.

Method 1: Update Mobile Number at an Aadhaar Enrollment Center

This method requires a physical visit to an authorized Aadhaar enrollment center. It is the most reliable option, especially if you do not have access to a registered mobile number or if your biometrics need re-verification.

1. Locate the nearest Aadhaar Enrollment Center – Visit the official UIDAI website (uidai.gov.in) and use the “Locate Enrolment Center” tool. Enter your city or pin code to find the closest center. Ensure the center is officially authorized by UIDAI to avoid fraud.
2. Carry required documents – Bring your original Aadhaar card (physical or digital copy via mAadhaar app) and a valid proof of identity. Acceptable documents include a passport, driver’s license, voter ID, or PAN card. You do not need to carry proof of address for a mobile update, but having it may help in case of additional verification.
3. Fill out the Aadhaar Update Form – At the center, request the Aadhaar Update Form (Form No. 002). Fill in your personal details, including your 12-digit Aadhaar number, current name, and the new mobile number you wish to register. Double-check the number for accuracy before submission.
4. Provide biometric authentication – A technician will capture your fingerprints and iris scan to verify your identity. This step is mandatory and ensures that only the rightful owner of the Aadhaar number can make changes.
5. Submit the form and pay the fee – The update fee is ₹50 (inclusive of GST), payable via cash, debit/credit card, or UPI. After payment, you will receive an acknowledgment slip with a Unique Reference Number (URN).
6. Wait for confirmation – The update is typically processed within 5–7 working days. You will receive an SMS notification on your new mobile number once the update is complete. You can also track the status using the URN on the UIDAI website.

Method 2: Update Mobile Number Online via UIDAI Portal

If you have access to a registered mobile number linked to your Aadhaar, you can update your mobile number online without visiting a center. This method is faster and more convenient for users with digital literacy.

1. Visit the official UIDAI website – Go to uidai.gov.in and click on “My Aadhaar” in the top menu. Then select “Update Mobile Number” under the “Aadhaar Services” section.
2. Enter your Aadhaar number – Type your 12-digit Aadhaar number and click “Send OTP.” An One-Time Password (OTP) will be sent to your registered mobile number.
3. Verify OTP – Enter the OTP received on your current registered mobile number. This confirms your identity and grants access to the update portal.
4. Enter new mobile number – Type your new mobile number twice to confirm. Ensure the number is active and belongs to you, as all future communications will be sent to this number.
5. Request new OTP – Click “Send OTP” again. This time, the OTP will be sent to your new mobile number.
6. Confirm with new OTP – Enter the OTP received on your new mobile number. This final step validates ownership of the new number.
7. Complete the update – Once verified, you will see a success message. A confirmation SMS will be sent to your new mobile number within 24–48 hours. You can also download the updated e-Aadhaar from the UIDAI website using your Aadhaar number and the new mobile number for authentication.

Important Notes

There are a few key limitations to be aware of when updating your mobile number:

• You can update your mobile number only twice in your lifetime. This restriction prevents misuse and ensures data integrity.
• If you have already used both updates, you must visit an enrollment center for any further changes. Biometric verification will be required, and additional documentation may be requested.
• Ensure the new mobile number is not already registered to another Aadhaar. Each mobile number can be linked to only one Aadhaar number.
• Do not use temporary or virtual numbers. The system may reject updates if the number is flagged as non-compliant with telecom regulations.

Best Practices

To ensure a smooth and secure mobile number update process, follow these industry-tested best practices:

Verify Your Current Mobile Number Before Updating

Before initiating any update, confirm whether your current mobile number is still active and correctly linked to your Aadhaar. You can do this by visiting the UIDAI website and selecting “Verify Mobile Number.” If the system does not recognize your current number, you may need to visit an enrollment center instead of attempting an online update.

Use Only Official Channels

Always use the official UIDAI website or authorized enrollment centers. Avoid third-party websites or apps claiming to offer “fast Aadhaar updates” for a fee. These are often scams designed to harvest personal data. Look for the UIDAI logo, HTTPS encryption, and official domain names (uidai.gov.in or myaadhaar.uidai.gov.in).

Keep a Record of Your URN

After submitting your update request—whether online or in person—retain your Unique Reference Number (URN). This number is your only proof of submission and is required to track the status of your request. Save it in a secure digital location or print a copy.

Update All Linked Services

Once your mobile number is updated in Aadhaar, immediately update it in all linked services. This includes your bank accounts, mutual fund portfolios, income tax portal, insurance policies, and digital wallets. Failure to do so may result in service disruptions or security alerts.

Enable SMS Alerts for Aadhaar Updates

Register for SMS alerts from UIDAI by visiting the “Aadhaar Services” section on their website. This ensures you receive instant notifications for any future changes to your Aadhaar profile, including address, name, or biometric updates.

Use mAadhaar App for Digital Access

Download the official mAadhaar app from the Google Play Store or Apple App Store. It allows you to view your digital Aadhaar, update your mobile number (if eligible), and receive real-time notifications. The app uses biometric and OTP-based authentication and is the most secure way to manage your Aadhaar digitally.

Update During Off-Peak Hours

If updating online, avoid peak hours (10 AM to 4 PM on weekdays), when the UIDAI portal may experience higher traffic. Early morning or late evening updates tend to have faster response times and fewer errors.

Double-Check Mobile Number Format

Always enter your mobile number in the 10-digit format without country code (+91), hyphens, or spaces. For example: 9876543210. Incorrect formatting is a common cause of failed submissions.

Tools and Resources

Several official tools and digital resources are available to assist you in updating your mobile number in Aadhaar. These are developed and maintained by UIDAI to ensure security, accuracy, and ease of use.

1. UIDAI Official Website

https://uidai.gov.in is the primary portal for all Aadhaar-related services. It provides access to the mobile update feature, status tracking, e-Aadhaar downloads, and a comprehensive FAQ section. Always bookmark this site and use it as your primary reference.

2. mAadhaar Mobile Application

The mAadhaar app is a secure, government-backed mobile application that allows you to manage your Aadhaar profile on the go. Features include:

• View and share your digital Aadhaar card
• Update mobile number (if eligible)
• Lock/unlock biometrics
• Generate Virtual ID (VID)
• Receive real-time alerts for profile changes

Download the app only from official app stores. Avoid third-party versions.

3. Aadhaar Enrollment Center Locator

4. e-Aadhaar Download Portal

After updating your mobile number, you can download your updated e-Aadhaar from https://eaadhaar.uidai.gov.in. You’ll need your Aadhaar number and the new mobile number to receive an OTP for authentication. The downloaded PDF is digitally signed and legally valid.

5. UIDAI Helpline Portal (Online Support)

While direct phone support is not provided, UIDAI offers an online grievance redressal system through its “Contact Us” page. You can submit queries, upload documents, and track responses. Responses are typically provided within 3–5 business days.

6. National Academic Depository (NAD) and DigiLocker

Once your mobile number is updated, link your Aadhaar to DigiLocker or NAD to store your e-Aadhaar securely in the cloud. These platforms allow you to share verified documents with educational institutions, employers, and banks without physical copies.

7. Aadhaar Authentication APIs (For Developers)

For organizations and developers integrating Aadhaar-based authentication into apps or services, UIDAI provides secure APIs for mobile number verification and OTP-based authentication. These are available under the “Developer Resources” section of the UIDAI website.

Real Examples

Understanding real-life scenarios helps clarify how the mobile number update process works in practice. Below are three detailed case studies based on actual user experiences.

Example 1: Priya, a College Student in Bengaluru

Priya, a 21-year-old student, had her Aadhaar linked to her parents’ old mobile number. She recently got her own SIM card and needed to update her Aadhaar to receive scholarship disbursements and government aid. She visited the nearest Aadhaar center near her college.

She carried her Aadhaar card and college ID as proof of identity. The technician verified her biometrics and submitted her new number. She paid ₹50 and received a URN. Two days later, she received an SMS confirming the update. She immediately updated her number on the National Scholarship Portal and linked her bank account. Within a week, her scholarship was credited successfully.

Example 2: Rajesh, a Business Owner in Jaipur

Rajesh, a 45-year-old entrepreneur, needed to update his mobile number because his old SIM was deactivated due to non-renewal. He had already used both online updates allowed in his lifetime. He could not use the online portal and had to visit an enrollment center.

At the center, he presented his Aadhaar card, PAN card, and business registration document. After biometric verification, the operator updated his number. He was informed that this was his final update. Rajesh then updated his mobile number on the GST portal, income tax e-filing site, and his company’s digital payment platforms. He now uses the mAadhaar app to monitor his profile.

Example 3: Anjali, a Senior Citizen in Varanasi

Anjali, 68, was struggling to update her mobile number because she didn’t have a smartphone and was unfamiliar with digital processes. Her daughter helped her locate the nearest center and accompanied her. They carried her Aadhaar card and ration card as proof of identity.

The center staff assisted her in filling out the form and explained each step. After biometric verification, Anjali received the confirmation SMS on her new number. She now uses the number to receive pension alerts and health scheme notifications. Her daughter also enrolled her in a local digital literacy program to help her use the mAadhaar app.

This error occurs when the number you’re trying to link is already associated with another Aadhaar. You must use a different number that is not linked to any other Aadhaar. You can check the status of a mobile number using the “Verify Mobile Number” feature on the UIDAI website.

Can I update my mobile number if my Aadhaar is locked or deactivated?

If your Aadhaar is locked due to biometric authentication failures, you must first unlock it at an enrollment center. Once unlocked, you can proceed with the mobile number update. Deactivated Aadhaar cards cannot be updated until reactivated through UIDAI’s official process.

Will updating my mobile number affect my Aadhaar card’s validity?

No. Updating your mobile number does not change the validity or status of your Aadhaar card. It only updates the contact information associated with your unique identity number.

How do I know if my mobile number update was successful?

You will receive an SMS on your new mobile number confirming the update. You can also check the status using your URN on the UIDAI website or download your updated e-Aadhaar from the official portal.

Can I update my mobile number if I’m outside India?

No. Mobile number updates must be done within India. If you are abroad, you can update your number once you return. Alternatively, you can authorize a family member in India to visit an enrollment center on your behalf, but only if you have previously registered a proxy through UIDAI’s official proxy update process.
