Activating your new Citibank card is the very first step before you can start using it for purchases, online payments, or ATM withdrawals. The process is simple, secure, and can be completed in just a few minutes through CardActivation.citi.com. 

Why Card Activation Matters

Before you can use your new Citibank card for shopping, online payments, or ATM withdrawals, activation ensures your card is linked to your account and ready for secure transactions.

Step 1: Open the Website

Go to CardActivation.citi.com in your browser.

Make sure the link starts with https:// for security.

Step 2: Enter Card Details

Type in your card number, expiration date, and CVV (the three‑digit code on the back).

Step 3: Verify Your Identity

Citibank will send a one‑time password (OTP) to your registered mobile or email.

Enter the OTP to continue.

Step 4: Create Online Access

Step 5: Confirm Activation

Once verified, you’ll see a message that your card is active.

You can now use it for shopping, online payments, and ATM withdrawals.

Step 6: Secure Your Card
