Aadhaar serves as a single source of identity verification to avail various services, both offline and online. Since it is empowered by Biometric Fingerprint authentication, it is less prone to fraud and hacking. It helps service providers in streamlining their customer base and clearing out duplicate or fake connections.

BSNL offers a few simple ways for you to link your Aadhaar with your BSNL mobile connection. A customer can have multiple BSNL mobile connections under their name but all the connections have to be linked to their Aadhaar number. The linking can be done offline at the BSNL store, through the OTP method or through the IVR option on the BSNL customer care number.


This method can be used by any customer wanting to link multiple BSNL connections to a single Aadhaar number. Multiple linking is not possible through the OTP or IVR method.

Step 1: Walk in to the nearest BSNL Store. Remember to carry the mobile number you want to link to Aadhaar

Step 2: Mention your BSNL number and submit a self-attested copy of Aadhaar to the store executive

Step 3: BSNL will send an OTP to your mobile number

Step 4: Submit the OTP to the store executive and verify your biometrics (fingerprint) information

Step 5: BSNL will send you an SMS confirmation in the next 24 hours. You have to reply ‘Y’ to this message to complete the linking

Step 6: You will receive an SMS confirmation once the linking is successful


This method is available for mobile numbers already registered with UIDAI under your Aadhaar number. The process is very simple.

Step 1: The Government introduced a toll-free number 14546 for Aadhaar linking - This number is common for all telecom operators, whether prepaid or postpaid connections. You have to call this number

Step 2: You will be asked to confirm whether you are an Indian citizen or an NRI

Step 3: You have to then give consent to your operator for re-verifying your number with Aadhaar

Step 4: Then enter your 12-digit Aadhaar number. The IVR will read it back and you can confirm it by pressing ‘1’

Step 5: An OTP is sent to your mobile number

Step 6: You are again asked to give consent to your operator to verify your personal details like Name, Photo and DOB from the UIDAI database

Step 7: The IVR will repeat the last 4 digits of your mobile number

Step 8: If it is correct, you need to enter the OTP received

Step 9: Press ‘0’ in case you do not have any additional BSNL connections

Step 10: Your Aadhaar re-verification request will be successfully accepted

Step 11: BSNL will send you an SMS confirmation in the next 24 hours. You have to reply ‘Y’ to this message to complete the linking

Step 12: You will receive an SMS confirmation once the linking is successful


You can easily link Aadhaar with your mobile connection by following the instructions on the BSNL Customer Care IVR. The steps are given below

Step 1: Call the BSNL toll free customer care number

Step 2: On the IVR, select the option to link Aadhaar with mobile number

Step 3: Enter your 12 digit Aadhaar number. The IVR will read it back and you can confirm it by pressing ‘1’

Step 4: Within 24 hours, you will receive an SMS confirming that your Aadhaar has been linked with your BSNL number

Please note that this method too will work only if the mobile number is the one registered to your Aadhaar on the UIDAI database.


Aadhaar serves as an identity verification document for all Indians. It aims at controlling miscreants from misusing the system for fraudulent and illegal activities. It helps put a check on the black money menace that has been corroding the economy and preventing the benefits from reaching the deserved. Apart from these benefits, it also helps with the e-KYC process that is mandatory for various financial services like bank accounts, share trading, mutual fund investments and insurance policies. A mobile number linked with your Aadhaar will also help you to e-verify your Income Tax Returns without any paper documentation.
