How to Link Mobile Number with Aadhaar Card

Linking your Aadhaar card with your mobile number takes just a few minutes and it unlocks every OTP-based UIDAI service, from downloading e-Aadhaar to completing e-KYC. UIDAI officially supports three methods: visiting an Aadhaar Seva Kendra in person (mandatory for first-time linking), updating via the UIDAI portal if a number is already registered, and using the mAadhaar app.

As per UIDAI, a registered mobile number is required to access Aadhaar services like OTP authentication, e-KYC, downloading e-Aadhaar, and updating details online through the official portal myaadhaar.uidai.gov.in.

Why You Should Link Aadhaar with Your Mobile Number

  • Download e-Aadhaar instantly
  • Complete e-KYC for banks and SIM cards

Note: If no mobile number is linked, you must visit the Aadhaar Seva Kendra.

Frequently Asked Questions

Yes, but only if a mobile number is already registered.

Not mandatory for all, but required for OTP services.

Yes. You do not need your old number to update the mobile number in Aadhaar. Visit any Aadhaar Enrolment Centre with just your Aadhaar number and the new mobile number. The centre verifies your identity through biometrics, fingerprint or iris, not through OTP on the old number.

No documents are required for mobile number update in Aadhaar. Only biometric verification (fingerprint or iris scan) is done at the centre to confirm your identity. This is different from address or name updates, which require supporting documents.

As per UIDAI, 90% of update requests are completed within 30 days. In some cases it can take up to 90 days. You will receive a confirmation SMS on your new mobile number once the update is processed. You can also track the status using your URN at myaadhaar.uidai.gov.in.

Yes. There is no restriction on the number of Aadhaar cards that can be linked to one mobile number. A parent's number can be registered against their children's Aadhaar, for example. However, UIDAI advises linking a number you have direct access to since it is used for OTP authentication.

If you did not register a mobile number at the time of enrolment, you need to visit a Permanent Enrolment Centre to get it added. The process is the same, fill the update form, complete biometric verification, pay ₹50, and collect the acknowledgement slip with your URN.
