As a cardholder, you can call Citi’s Customer Service at 1-888-248-4226 or log in to your online account and easily increase your credit limit.

Request a credit limit increase online from the Citibank credit card login page for your account.
When you log in to your Citi account, click on “Services” and select “Card Services.” You can then choose either a Temporary Credit Limit Increase or Permanent Credit Limit Increase. You’ll need to provide your card number, desired credit limit, effective date, and reason for the increase. When you’re done, click “Next” to finish applying. Temporary increases to credit limit on Citi cards last up to 60 days from the date of approval.
If you don’t already have an online account with Citi, you can click on the gray “Register” button to sign up. For your Citi card login, you’ll need your credit card number, security code, and the last four digits of your social security number.
It could be that your Citi card has a low credit limit because of your credit history, but this doesn’t have to hold you back. As a responsible and longstanding Citi cardholder, you can qualify for another card with a higher credit limit.
Pick out a Citi Card that’s right for you!
Whether it’s the Citi® Secured MasterCard® or Citi ThankYou® Preferred Card, a new credit card could be exactly what you need to start fresh with an increased credit limit. It can also be a good time to re-evaluate your spending habits and needs to ensure the card you’re using every day is the best one for your lifestyle.
