How to contact Citibank credit card customer service
Citibank operates a dedicated customer service line for credit card holders. The main number is 1-800-950-5114, available 24 hours a day, seven days a week. When you call, have your card number and a form of ID ready — the automated system will ask for both before routing you to a representative.
You can also reach customer service through your online account. Log into your Citi credit card portal, select "Contact Us" from the menu, and choose whether you want to chat with someone, request a callback, or send a find message. The callback option is useful if you do not want to wait on hold — you provide a time window and Citibank calls you back.
If you prefer to write rather than call, you can mail correspondence to Citibank's credit card customer service address, which appears on your monthly statement. Mail takes longer than phone or online contact, typically one to two weeks for a response.

What to do if your card is lost or stolen
Call 1-800-950-5114 when ready if your card is missing or you suspect fraud. A representative will freeze your account right away so no one else can use it. You do not need to wait for a letter in the mail — the freeze happens during the call.
Citibank will send you a replacement card within five to seven business days. The new card arrives with a different number, so update any recurring charges (subscriptions, automatic bill payments, gym memberships) once you receive it. If you need the card faster, ask the representative whether expedited shipping is available in your area — some locations can receive a card in two to three business days, though this may carry a fee.
Disputing a charge on your statement
If you see a charge you do not recognize or believe is wrong, call customer service or log into your online account and select the transaction. You can start a dispute through either method. Citibank will investigate and typically respond within 30 days, though some disputes take longer if the merchant contests the claim.
While the dispute is being reviewed, the charge may remain on your statement, but Citibank will not report it as late or delinquent. Keep records of any communication with the merchant — emails, receipts, or written correspondence — and have them ready when you contact customer service. The more documentation you provide, the faster the investigation usually moves.
Updating your account information
You can change your address, phone number, or email through your online account without calling. Log in, go to "Account Settings" or "Profile," and update the information directly. Changes usually take effect within one business day.
If you need to update your name due to marriage, divorce, or legal change, you will need to call customer service. A representative will walk you through what documents Citibank needs — typically a marriage certificate, divorce decree, or court order — and explain how to submit them. Processing name changes takes longer than other updates, usually two to three weeks.
Requesting a credit limit increase or decrease
You can request a credit limit change through your online account. Log in, find the option for "Credit Limit" or "Account Management," and enter the new amount you want. Citibank will review your request and usually respond within one business day.
If you prefer to speak with someone, call customer service and ask to discuss your credit limit. A representative can tell you whether you are may be able to access for an increase based on your payment history and account status. Decreasing your limit can usually be done when ready over the phone, while increases may require a review of your credit.
Reporting a billing error or unauthorized charge
Billing errors and unauthorized charges are handled differently. An unauthorized charge is one someone else made without your permission — report this when ready by calling 1-800-950-5114. A billing error is a charge that appears incorrect on your statement, such as being charged twice for the same purchase or charged the wrong amount.
For either issue, have your statement in front of you and be ready to describe the transaction in detail: the merchant name, the date, and the amount. Citibank will document your report and begin an investigation. You have the right to dispute charges within 60 days of the statement date, so report problems as soon as you notice them.
Understanding your statement and account activity
Your monthly statement shows all transactions, fees, interest charges, and your minimum payment due. If something on your statement is unclear, customer service can explain any charge or fee. Common questions include why interest was charged, how the minimum payment was calculated, or what a particular merchant code means.
You can also view your account activity online in real time. Log into your portal and select "Transactions" or "Activity" to see charges as they post, usually within one to two business days of purchase. This lets you catch errors or fraud faster than waiting for your monthly statement.
Frequently Asked Questions
How long does it take to speak with someone when I call?
Wait times vary depending on call volume and time of day. Early morning and late evening typically have shorter waits than midday. If you do not want to hold, use the callback feature in your online account and Citibank will call you at a time you choose.
Can I close my credit card account over the phone?
Yes. Call customer service and tell the representative you want to close your account. They will confirm your identity, review your balance, and process the closure. Make sure you have paid off any remaining balance or arranged a payment plan before closing.
What if I cannot pay my bill on time?
Call customer service before your payment is due. A representative can discuss your options, which may include a payment plan, temporary hardship program, or deferment of interest. Calling before you miss a payment is much better than calling after, as it may prevent late fees and damage to your credit.
Is there a fee to speak with customer service?
No. Calling Citibank customer service is free. The 1-800 number is toll-free, and there are no charges for phone, chat, or find messaging through your online account.
What information do I need before calling?
Have your credit card number, the phone number associated with your account, and a form of ID ready. If you are calling about a specific transaction, have your statement or the transaction details available so you can describe it accurately.
