How to Link Your Mobile Number with Aadhaar Online & Offline Methods
June 25, 2025
Linking your mobile number with Aadhaar is essential if you want to access Aadhaar-based services like e-KYC and Video KYC for bank accounts, OTP verification, filing taxes, e-Aadhaar downloads, and biometric authentication. Without a registered mobile number, you can't use any online Aadhaar services.
Whether you're updating an old number or registering a new one, this guide explains how to link your mobile number with Aadhaar — using both online and offline methods. Let’s dive in!
Why Linking Aadhaar with Your Mobile Number is Important
When Should You Update Your Mobile Number in Aadhaar?
You should consider linking or updating your Aadhaar mobile number in the following situations:
How to Link Aadhaar with Mobile Number Online (via India Post)
While UIDAI doesn’t offer a direct online method yet, India Post provides a convenient doorstep service that you can book online.
Steps to Link Mobile Number with Aadhaar via India Post:
1. Visit: ccc.cept.gov.in
2. Choose ‘UIDAI-Mobile/Email Update’ service
3. Fill in your name, Aadhaar number, mobile number, Address and PIN code
4. Submit OTP received on your mobile
5. Get a Service Request Number to track your application
6. An officer will visit your home with a biometric device to verify your identity
7. On successful authentication, your mobile number gets linked
The fee is approximately ₹50 and the processing time is 7–14 working days.
How to Link Aadhaar with Mobile Number Offline (via Aadhaar Seva Kendra)
For most users, especially those without access to doorstep service, visiting an Aadhaar Seva Kendra is the preferred method.
Steps to Link Mobile Number at Aadhaar Centre:
1. Locate a nearby Aadhaar Seva Kendra at appointments.uidai.gov.in
2. Fill the Aadhaar Update/Correction Form
3. Provide Aadhaar number, valid proof of identity (PAN, voter ID, etc.) and new mobile number to be linked
4. Undergo biometric authentication (fingerprint or iris scan)
5. Pay the update fee and collect your URN (Update Request Number)
6. Track status via UIDAI portal or call 1947
The fee is approximately ₹50 and the processing time is 3–10 working days (can take up to 30 days).
Linking Mobile Number During Aadhaar Enrolment
If you’re applying for Aadhaar for the first time — for yourself or your child — you can register your mobile number during enrolment. This ensures the number is linked from Day 1, and there's no need for a separate update request.
You can also link or change the number during child Aadhaar updates at ages 5 and 15, when biometrics need to be re-submitted.

Final Thoughts
Linking your mobile number to Aadhaar is not just a good idea — it's practically necessary in today’s digital world. Whether you prefer the convenience of doorstep linking via India Post or choose to walk into an Aadhaar centre, the process is simple and affordable. By late 2025, UIDAI is expected to allow full online updates for mobile numbers, making this even easier. Until then, use the methods above to ensure your Aadhaar stays current and accessible.
