Compare Citi credit cards
Now that your Citi card is activated, you can start using it. Down the line, you may feel the need for a higher credit line or perks and features that your current Citi card lacks. Pairing cards can also help you maximize rewards. For example, if you now earn flat rewards on all purchases, consider a card with accelerated gas rewards or rewards in any other category where you spend most. The cards in the table below may be strong secondary options.
Just like the process to activate other credit cards, there are three simple ways to activate your Citi credit card. 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.
