Why Updating Your Aadhaar Mobile Number Matters?

Before diving into how to change mobile number in Aadhaar, it's essential to understand why it's so important:

• OTPs for government services like PAN-Aadhaar linking, income tax filing, and voter ID updates are sent to your Aadhaar-linked mobile number.
  
  
• Services like mAadhaar app, Umang app, and Aadhaar authentication for eKYC require your mobile number to be active.
  
  
• Many banks and digital wallets verify user identity via Aadhaar OTP authentication.
  
  

Importance of Updating Aadhaar Mobile Number – Real-Life Scenarios

Who Can Change Their Mobile Number in Aadhaar?

Anyone with an existing Aadhaar card, irrespective of age or location, can initiate a mobile number update. Even children’s Aadhaar can be updated by their guardians.

Take the case of Mrs. Dsouza, a senior citizen in Pune. Her mobile number was deactivated due to inactivity. She needed help accessing her pension account. Her grandson guided her on how to change mobile number in Aadhaar, and within 48 hours, her access was restored.

How to Change Mobile Number in Aadhaar: Step-by-Step

Here’s a breakdown of the process.

1. Visit the Nearest Aadhaar Seva Kendra (ASK)

There’s no online method available currently to directly change your Aadhaar-linked mobile number. This is a security measure to prevent misuse. You must visit an authorised Aadhaar Enrolment Centre or Aadhaar Seva Kendra (ASK).

To locate one:

• Visit the UIDAI website.
  
  
• Use the “Locate Enrolment Centre” option.
  
  

Example: If Shalini, a student in Chennai, is living on her university campus, she can enter her campus postcode to find the nearest Aadhaar Kendra within 2–3 km radius.

2. Fill in the Aadhaar Correction/Update Form

At the centre:

• Ask for the Aadhaar Update Form.
  
  
• Tick only the “Mobile Number” update box.
  
  
• Enter your new 10-digit mobile number clearly.
  
  
• Submit it with biometric authentication (fingerprint or iris scan).
  
  

Important: No need to bring any additional documents just to change your mobile number.

3. Pay the Required Fee

As of now, the UIDAI charges ₹50 for each update request.

Quick Calculation Example:

This table helps visualise how small individual charges can scale up to generate substantial revenue when millions of users make Aadhaar mobile updates.

4. Collect the Acknowledgement Slip

After submitting your request:

• You’ll receive an Update Request Number (URN).
  
  
• Use this URN to track your update status at uidai.gov.in.
  
  

5. Wait for the Update

Your mobile number usually gets updated within 3 to 10 working days. In many urban centres, the process may be faster.

In Rohan’s case he’s a tech consultant in Noida. He visited the Aadhaar Seva Kendra on Monday and got a confirmation SMS by Thursday. That’s just 4 days.

How to Check If Your Mobile Number Is Updated in Aadhaar

Once you’ve followed all the steps on how to change your mobile number in Aadhaar, here’s how you can confirm the update:

• Visit https://resident.uidai.gov.in/verify-email-mobile
  
  
• Enter your Aadhaar number and new mobile number
  
  
• If your number is linked, you’ll get an OTP
  
  

This confirmation is especially useful if you've recently changed telecom providers or ported your number.

Example – Confirming Mobile Number Update in Aadhaar

Note:

• You can only receive the OTP if your mobile number is already linked to Aadhaar.
  
  
• UIDAI recommends waiting 48–72 hours after updating your number before trying to verify.

What If You Don't Have the Old Mobile Number?

Unlike other digital services, UIDAI doesn’t require access to your old number to update the new one.

For example, Arvind, a construction worker in Ahmedabad, lost his old number and SIM. He didn’t remember his telecom provider or the last recharge. Still, he walked into the nearest update centre and changed his Aadhaar-linked number in one visit.

That’s the beauty of the Aadhaar update system: No dependence on telecom service history.

Can You Change Your Mobile Number in Aadhaar Online?

A common myth is that one can log into the mAadhaar app or UIDAI portal and change the number online. This is false.

Currently, UIDAI allows only demographic updates like name spelling correction or address changes via online channels, but not mobile number changes. This ensures high security.

Conclusion

Knowing how to change mobile number in Aadhaar is not just about tech updates. It is about ensuring seamless access to essential services, from healthcare to digital banking. Whether you’re a student like Shalini, a senior like Mrs. Dsouza, or a gig worker like Rajesh, your mobile number is the bridge to India's digital identity ecosystem.

So, don’t wait until you're locked out; if your number has changed, head to your nearest Aadhaar Seva Kendra and get it updated today.

And remember: when it comes to digital security and service access in India, your answer always starts with knowing how to change mobile number in Aadhaar.
