Can I link a family member's mobile number to my Aadhaar if I don't have my own number?

UIDAI recommends linking your own personal mobile number. However, technically you can link any active mobile number. Keep in mind that the linked number receives all OTPs for your Aadhaar — whoever holds that number controls access.

I linked my mobile number 3 days ago but OTP is still not coming on Aaple Sarkar. Why?

NPCI and UIDAI systems can take up to 72 hours to sync. If it has been more than 3 days, check the status using your URN at myaadhaar.uidai.gov.in. If confirmed updated, try clearing your browser cache and retrying.

Is mobile linking free or does it cost money?

Mobile linking at an Aadhaar Seva Kendra costs ₹50. This is the standard fee for any Aadhaar update done at a centre.

How to Link Mobile Number to Aadhaar

In Simple Words: Without a mobile number linked to Aadhaar, you cannot receive the OTP needed to log into Aaple Sarkar, download your Aadhaar, or do any online update. You cannot link a mobile number online — you must visit an Aadhaar Seva Kendra in person. It takes about 10 minutes and costs ₹50.

Why This Matters for Maharashtra Applications

Every online service on Aaple Sarkar uses Aadhaar OTP verification to confirm your identity. If no mobile is linked, you cannot:

Log into Aaple Sarkar to apply for certificates
Download your e-Aadhaar online
Do any Aadhaar update online
Apply for scholarships on MahaEschol

Linking your mobile is the first thing to fix if you’re having trouble with any government application.

Important: This Cannot Be Done Online

For security reasons, UIDAI does not allow mobile number linking or changes through the website or app. You must physically visit an Aadhaar Seva Kendra or Aadhaar Enrolment Centre.

What You Need to Carry

Your Aadhaar card (original or photocopy)
The mobile number you want to link (make sure it is active and with you)
No additional documents needed — biometric verification confirms your identity

Steps to Link Mobile Number

Find your nearest centre at uidai.gov.in → Locate Enrolment & Update Centre
Visit during working hours (Monday–Saturday, 9 AM–5 PM)
Tell the operator: “I want to link/update mobile number in Aadhaar”
Provide your Aadhaar number and the mobile number to be linked
Give your fingerprint or iris scan for biometric verification
Pay ₹50 fee
Collect your Acknowledgement Slip with URN

Processing time: 48–72 hours (usually faster)

How to Check if Mobile is Successfully Linked

After 2–3 days:

Go to myaadhaar.uidai.gov.in
Enter your Aadhaar number and the mobile number you linked
If an OTP is delivered to that number, the linking is successful

Or check via URN:

Go to myaadhaar.uidai.gov.in → Check Aadhaar Update Status
Enter your URN — status should show “Updated”

Changing an Existing Linked Mobile Number

If your old mobile number is no longer active and you want to replace it with a new one — the process is the same. Visit the Aadhaar Seva Kendra, give biometric verification, and provide the new number.

You cannot do this remotely or by calling any helpline.
