What’s next?

Now that your Citi card is activated, it’s time to start using it. Here are your next steps once you’ve activated your card:

  • Log in to your Citi account. You can confirm your card’s activation by logging into your Citi account, or creating one if you haven’t. This is also where you can review your card’s rates and fees, as well as its perks and features. These features can offer a lot of value, so it pays to keep them in mind.
  • Start earning rewards. Citi offers a wide variety of rewards cards and several Citi rewards programs to go with it. Depending on which rewards card you get, you’ll want to start spending in certain areas to pump up your reward earnings.
  • Redeem your rewards. Once you’ve earned a good number of points or miles, it’s time to spend them. The Citi ThankYou Rewards program has several different ways to redeem your points. Some more valuable than others, so check out our guide to make the best use of your points. Similarly, the American Airlines AAdvantage program offers several ideal ways to redeem your AAdvantage miles.

Bottom line

Just like the process to activate other credit cards, there are three simple ways to activate your Citi credit cards. You can activate your card by phone, online or with the Citi mobile app. If you’re ready to get a higher credit limit and additional perks, consider adding a secondary credit card to your wallet.
