Citibank Customer Care Numbers: A Practical, Up-to-Date Guide

Getting the right Citibank customer care number depends on your country and the product you hold (credit card, checking/savings, loans, or wealth). Below is a field-tested guide to the fastest ways to reach the correct team, how to prepare before you call, and trusted official links so you can verify the latest details.

For the most current contact options by country, always start with the official site: citi.com (country selector) or citi.com/contactus (United States). Because product support is region-specific, calling the number for your card’s country of issuance will save you time.

Quick Access Phone Numbers (verified entry points)

Use these high-traffic lines as your first stop; they are staffed to route you to specialized teams after basic verification. Availability and routing may vary during system maintenance or regional holidays.

• United States (Citi credit cards, general servicing): 1-800-950-5114 — 24/7. TTY users can dial 711 to use the Telecommunications Relay Service and ask for 1-800-950-5114.
• Outside the U.S. (for U.S.-issued Citi credit cards, call collect): 1-605-335-2222 — 24/7. Ask the local operator to place a collect call to 1-605-335-2222.
• Singapore (CitiPhone Banking, all retail customers): +65 6225 5225 — 24/7. Official contact page: citibank.com.sg/contact-us
• Global country/region selector: citi.com → choose your country, then navigate to “Contact Us” for locally issued cards and accounts.

If your card or account was opened in a different country, use that country’s “Contact Us” page for the most accurate number and hours. Many countries offer language-specific lines and shorter IVR menus if you dial the local number printed on the back of your card.

How to Reach the Right Team Faster

Have your card number or customer ID handy. For security, agents typically verify at least two items: full name as on the account, date of birth, and either the last 4 digits of your card or a one-time passcode sent to your phone/email. If you’re calling from a new phone number, expect an additional verification step.

Use the number printed on the back of your card whenever possible; it typically routes you directly to the team that manages your specific product (e.g., premium cards, co-branded cards, or wealth accounts). If the back-of-card number is unavailable, start with a national line like 1-800-950-5114 (U.S. cards) and say “representative” after the initial prompt. Once connected, ask the agent to transfer you to the correct specialty queue (credit limit, fraud, disputes, travel alerts, rewards/points, or balance transfers).

Digital and In-App Support (often quicker than calling)

The Citi Mobile App and Citi Online can solve many issues without a phone call. You can lock/unlock a card, replace a card, set travel notices, redeem ThankYou points, view and download statements, request credit line increases, and dispute charges. Log in at citi.com (U.S.: online.citi.com) or via the Citi Mobile App for iOS/Android.

For secure messaging, sign in and look for “Message Us” or “Need Help?” in the app or web portal. Secure messages route to the right back office automatically and include your account context, which can reduce back-and-forth and eliminate hold time. For general updates and outage notices in the U.S., @AskCiti on X (Twitter) provides real-time guidance, but never share full account numbers or sensitive data on social media.

What to Have Ready Before You Call

• Your card or account number (or the last 4 digits), government ID details for verification, and your registered mobile number for one-time passcodes.
• For disputes: the transaction date, merchant name, amount, and a brief reason (e.g., “duplicate charge,” “merchandise not received,” “canceled subscription”). Save any receipts, emails, or cancellation confirmations.
• For travel notices: exact trip dates, countries/cities you’ll visit, and the phone number where you can be reached abroad.
• For balance transfers or limit requests: the target amount, the last 4 digits of the receiving account (if applicable), and your monthly income for underwriting review.

Lost or Stolen Card, Fraud, and Disputes

If your card is missing or you see unauthorized transactions, act immediately. In the app, use “Lock Card” to prevent new purchases, then request a replacement. If you can’t access the app, call your local Citi customer care number right away. U.S. cardholders can call 1-800-950-5114 (or 1-605-335-2222 collect from abroad) 24/7. Replacement cards can often be expedited; ask about delivery options and fees for your card type.

For billing disputes, you generally have up to 60 days from the statement date (U.S., per the Fair Credit Billing Act) to open a dispute. File it via the app or website for the fastest processing; you will receive a case number and status updates. Continue paying undisputed portions of your bill while the investigation proceeds to avoid interest on valid charges.

Citibank India: Important Transition Note

Citigroup announced in April 2021 its exit from consumer banking in India, and the sale of Citibank India’s consumer business to Axis Bank closed on 1 March 2023. If your credit card or consumer account was issued in India, most servicing has moved to Axis Bank systems while honoring your existing Citi card number and benefits during the transition.

For the latest India-specific customer care numbers and servicing channels for former Citibank India consumer customers, use the official Axis Bank transition page: axisbank.com/citi. You can also start from citi.com, choose India, and you will be guided to the correct Axis support resources. Always rely on the numbers shown on your physical card and on the official Axis/Citi transition pages to ensure you’re reaching the correct team.

Fees, Hours, and Call Timing

Citibank does not charge for standard customer service calls, but your telecom provider may bill international or roaming charges. When dialing collect to 1-605-335-2222 from outside the U.S., ask the operator to confirm any fees before connecting. In many regions, credit card servicing is staffed 24/7; branch and mortgage lines may observe local business hours and public holidays.

If hold times are long, try the in-app “Message Us” option, or call during off-peak local hours. Keep your phone line available for verification texts or calls during the session; calls can sometimes be delayed if one-time passcodes are not received promptly.

Addresses, Branches, and Official Links

For escalations and formal correspondence in the United States, Citigroup’s corporate headquarters is at 388 Greenwich Street, New York, NY 10013. Note: payment and servicing mail addresses vary by product and state; always use the remittance address printed on your statement or shown in your online account to avoid processing delays.

Find country-specific customer care and branch/ATM locations via the official sites: citi.com (global selector), citi.com/contactus (U.S.), citibank.com.sg/contact-us (Singapore), and axisbank.com/citi (India consumer transition). Using the numbers printed on your card or listed on these pages will ensure you reach the correct, secure Citibank channel for your account.
