Most people discover their mobile isn't linked to Aadhaar at the worst possible moment — usually when they're trying to get an OTP for a loan, PM Kisan payment, or some urgent eKYC and nothing arrives. What surprises a lot of people is that there's no online fix for this: UIDAI requires you to physically walk into a centre and give your biometrics, even if you just want to swap one number for another. The good news is it's genuinely quick — ₹50 and about 15 minutes, and you're done.

Overview

Linking or updating your mobile number on Aadhaar cannot be done through an online self-service portal. It requires visiting an Aadhaar Seva Kendra (enrollment centre) in person for biometric verification. This design is intentional — UIDAI requires physical presence to prevent fraud when changing the contact number linked to your identity. Why is it important? Your registered mobile number is used to receive OTPs for all Aadhaar-based services: downloading eAadhaar, updating address, completing eKYC for PM Kisan and other DBT schemes, and banking/financial KYC. Without a registered mobile, you cannot use any of UIDAI's online self-service features. As of 2026, over 95 crore Aadhaar holders have a registered mobile number. If yours is not registered, or if you have changed your number, updating it at a Seva Kendra takes 10–15 minutes and costs ₹50. Note: Linking your Aadhaar to a bank account (for DBT benefits) is a separate process from registering your mobile with UIDAI — that can be done at your bank branch or via net banking.

Eligibility

  • Any Aadhaar holder can register or update their mobile number
  • No minimum age requirement — parents can update mobile for minor children
  • Physical presence at Aadhaar Seva Kendra is mandatory
  • Biometric authentication (fingerprint or iris) is required — if biometrics are locked, unlock first at myaadhaar.uidai.gov.in

Original Aadhaar card (physical card, printout, or eAadhaar on phone)
No additional documents required — biometric verification serves as identity proof
New mobile number you want to register (you will provide it at the counter)

Common Problems & Solutions

Wrong mobile number is currently linked to my Aadhaar
Visit any Aadhaar Seva Kendra and request a mobile number update. Provide your correct/new mobile number to the operator. Biometric verification ensures only you can change it. The update takes 2–5 working days to be effective.
Update done at centre but OTP still not coming on new number after 10 days
Track your update status using the URN on your acknowledgement slip at uidai.gov.in/check-aadhaar-status. If status shows 'Updated', try triggering OTP on myaadhaar.uidai.gov.in. If still not working, call UIDAI at 1947 with your URN. In rare cases, the update may need re-submission.
Lost my acknowledgement slip — don't have the URN
Call UIDAI helpline 1947 with your Aadhaar number and date of centre visit. The operator can look up your update request. Alternatively, try triggering an OTP at myaadhaar.uidai.gov.in after 5 working days from your centre visit — if OTP arrives on new number, the update is complete.

Frequently Asked Questions

Is there any online method to update mobile number on Aadhaar?

No. As of 2026, UIDAI does not offer any purely online method to register or update a mobile number on Aadhaar. Physical presence at an Aadhaar Seva Kendra with biometric verification is mandatory. This is a deliberate security measure to prevent unauthorized mobile number changes.

How do I know if my mobile number is registered with Aadhaar?

Try requesting an OTP at myaadhaar.uidai.gov.in using your Aadhaar number. If you receive an OTP on your mobile, it is registered. Alternatively, call UIDAI at 1947 and ask — they can confirm which mobile number (partial, masked) is registered against your Aadhaar.

Can I register my mobile number for Aadhaar and bank account at the same time?

These are two separate processes. Registering your mobile with UIDAI is done at an Aadhaar Seva Kendra. Linking Aadhaar to your bank account (for DBT) is done at your bank branch or via net banking/banking app — it is unrelated to UIDAI's mobile registration.
