Simply download the Citi Mobile App from the App Store or Google Play, then log in using your registered User ID and password. Once logged in, navigate to the “Card Services” or “Activate Card” option, select your new card, and follow the on-screen instructions to begin the activation process.
You will be asked to verify your identity, usually through an OTP sent to your registered mobile number or email.

Safely dispose of any old or expired cards by cutting them into pieces to prevent misuse.
