Aug 21, 2025
In India, Aadhaar has become one of the most important identity proofs for accessing various services, from opening a bank account to filing your taxes or getting government subsidies. To ensure added security and access to Aadhaar-enabled services, it is mandatory to link your Aadhaar with your mobile number. If you're wondering how to link Aadhaar with mobile number, this guide helps you with the entire process step by step.
Whether you're doing it for the first time or updating an old number, this simple guide covers both online and offline methods, making the process quick and stress-free
Why Linking Aadhaar with Your Mobile Number is Important
Aadhaar authentication is used across many services, including e-KYC, income tax filing, bank transactions, and receiving government benefits. It's important for you to understand why this step is necessary before we dive into understanding how to link Aadhaar with mobile number. Without Aadhaar mobile verification, you may be restricted from accessing many such services.
By linking your mobile number, you enable:
- OTP-based Aadhaar authentication
- Easy access to government services
- Secure online verification of your identity
Step-by-Step Guide
There are two ways you can link your Aadhaar with your mobile number: via OTP-based re-verification (if your number is already linked but needs to be reverified) or through biometric authentication at an Aadhaar Seva Kendra. Here's how:
1. OTP-Based Re-Verification (If Already Linked Earlier)
You can try this if your mobile number is already linked to your Aadhaar and you're asked to reverify it:
- Dial 14546 from your mobile phone.
- Follow the IVR instructions.
- Enter your 12-digit Aadhaar number on your keypad.
- You will have to give your consent by typing "1".
- Enter the OTP received on your Aadhaar-registered mobile.
- You will receive a confirmation SMS once verified.
2. How to Link Aadhaar with Mobile Number for the First Time
If your mobile number isn't linked yet, you must visit an authorised center:
- Visit the nearest Aadhaar Seva Kendra or an authorized service provider (like a telecom operator's outlet).
- Carry a self-attested copy of your Aadhaar card.
- Fill out the Aadhaar correction/update form.
- Provide your biometric details (fingerprint/thumb impression) for verification.
- Your request for mobile number update in Aadhaar will be processed.
- A nominal fee (usually ₹50) will be charged.
- Within 3-5 working days, you will get a confirmation SMS.
Can I Link Aadhaar with Mobile Number Online?
One of the most common questions people ask is whether Aadhaar mobile linking online is possible. As of now, for first-time linking or changing an unverified number, biometric verification is mandatory, so the offline process becomes mandatory.
However, if your number is linked and you want to update it online, you can do so through the UIDAI Self-Service Update Portal (SSUP), but only if your existing number is active and verified.
Online Aadhaar Mobile Number Update (If Already Linked):
- Go to the UIDAI website: https://uidai.gov.in
- Click on "Update Aadhaar Details (Online)"
- Enter your Aadhaar number and the OTP sent to your linked mobile.
- Select "Mobile Number" from the update list.
- Enter the new mobile number and submit.
- You will receive an URN for tracking.
This process is part of online Aadhaar mobile number update, applicable in specific scenarios only.
Aadhaar Mobile Linking Online: What to Remember
While the Aadhaar mobile linking online process is limited, UIDAI continuously works to make services accessible. You can avoid delays or issues by:
- Ensuring the number you want to link is active and accessible when you update it.
- Double-check your Aadhaar details before submission.
- Avoid agents who claim they can do this online without your biometric verification; it's not legitimate.
