How to Update Mobile Number and Email in Aadhaar — Complete Guide

Why Update Mobile Number or Email in Aadhaar?

Your mobile number linked to Aadhaar is essential for:

• OTP-based authentication for government services
• Downloading e-Aadhaar PDF online (see our e-Aadhaar download guide)
• Banking and financial services using Aadhaar eKYC
• Digital Locker and other DigiGov services
• Government scheme benefits (DBT, subsidies, scholarships)

If your mobile number has changed or was never registered, updating it should be a priority.

Methods to Update Mobile Number in Aadhaar

Method 1: Visit an Aadhaar Enrolment Centre (Recommended)

This is the most reliable method and works even if your old number is no longer active.

1. Locate the nearest centre — visit appointments.uidai.gov.in or search "Aadhaar centre near me"

3. Visit the centre with your original Aadhaar card and one valid ID proof
4. Fill the Aadhaar Update/Correction Form — tick the "Mobile" checkbox
5. Enter your new mobile number on the form
6. The operator will verify your biometrics (fingerprint/iris scan)
7. You will receive an acknowledgement slip with a Update Request Number (URN)
8. An OTP will be sent to your new mobile number for verification
9. Update will be processed within 7-10 working days

Method 2: Online via myAadhaar Portal (Limited)

Note: As of 2024, UIDAI allows limited online updates. Mobile number update may require a visit to the enrolment centre. Check the portal for current availability.

1. Visit myaadhaar.uidai.gov.in
2. Log in using your Aadhaar number and OTP on your currently registered mobile
3. Select "Update Aadhaar"
4. Choose "Mobile Number" or "Email" update
5. Enter the new mobile number or email
6. Verify via OTP sent to the new number/email
7. Submit the request

Method 3: Using mAadhaar App

1. Download mAadhaar from Play Store / App Store
2. Register with your current registered mobile number
3. Go to "Update Aadhaar" section
4. Follow the prompts to submit a mobile/email update request
5. Biometric verification may be required at a centre

How to Update Email Address in Aadhaar

2. Login with Aadhaar number + OTP
3. Select "Update Aadhaar" → choose "Email"
4. Enter your new email address
5. Verify via OTP/link sent to the new email
6. Submit

Offline (at Aadhaar centre):

For mobile number update at a centre, you need:

• Original Aadhaar card (or e-Aadhaar printout)
• Valid ID proof (any one):
  • Passport
  • PAN card
  • Voter ID
  • Driving License
• New mobile phone (to receive OTP at the centre)

How to Check Update Status

1. Visit myaadhaar.uidai.gov.in
2. Click on "Check Aadhaar Update Status"
3. Enter your URN (Update Request Number) from the acknowledgement slip
4. Enter the captcha and click "Check Status"

Important Tips

1. Always carry your phone with the new SIM when visiting the Aadhaar centre — OTP verification happens on the spot
2. Keep your URN safe — you need it to track your update status
3. Only one mobile number can be linked to one Aadhaar at a time
4. Update before your old SIM expires — if your old number is deactivated, you must visit a centre (online update won't work)
5. Aadhaar-linked services (bank, gas, etc.) will automatically use the new number after update is processed
