Linking your Aadhaar to your mobile number is essential for identity verification, accessing services such as banking and insurance, and keeping your personal information secure. When your mobile number is linked with Aadhaar, you can receive OTPs for transactions, retrieve your Aadhaar if needed, and use Aadhaar-based services without delay. You can link your number to Aadhaar either online or offline through authorised centres. Keeping your mobile number updated also ensures seamless access to PAN, bank accounts, investments and other financial activities.
How to Link a Mobile Number with an Aadhaar Card Online
If you prefer a doorstep option, you can initiate the update online via India Post Payments Bank (IPPB). The online process arranges a postal visit for biometric verification. Steps:
