You can activate a Capital One Platinum card online, through the Capital One mobile app or by phone. Activation requires both the 16-digit card number and the card’s security code. To minimize fraud, the card is not useable until it’s activated.
Here’s how to activate a Capital One Platinum card:
- Online: To activate the Capital One Platinum card online, sign in to your account or create an online account, if you don’t already have one. After logging into your account, click “Activate Your Card” on the account details page.
- Mobile App: Log in to the Capital One mobile app and tap “Activate a Credit Card.” Then, select the card you want to verify.
- By phone: Call the number on the back of the card and enter the 3-digit security code on the back of the card when prompted. Also, make sure to call from the phone number you provided on the application. Otherwise, you will have to answer the security question you created when you applied for the card.
Once activated, the Capital One Platinum card is immediately available for use.
