What Happens if I Decide Not to Activate?

Once you're approved for a Capital One credit card, you'll receive it in the mail within a few days. It's important to activate your card as soon as you get it to help prevent fraud.

If you don't activate it for any reason, you won’t be able to use the card or earn any rewards. The bank will send several reminders, and if you still don’t activate it, they may close the account due to inactivity.

In the long term, the inconvenience of closing your credit card account due to inactivity could affect your credit score. The application will still affect your credit, and you will still pay any outstanding fees.

What to Do After Activating Your Capital One Credit Card

After activating your Capital One credit card, it becomes ready for use. While Capital One has a variety of cards with different goals, there are things that you may want to do after activating your card:

  • Set up automatic payments. You can go automatic for your monthly bills on the credit card. Through this, you will not worry about missed or late payments. If you intend to use the card for recurring payments, ensure you update the card information with the merchants.
  • Add the card to your digital wallet. After activating your Capital One credit card, be sure to register for text alerts to keep track of your account. These alerts will keep you updated on any activity. You can also add your card to your digital wallet, so you can use it even without the physical card.
