Citibank Customer Care Numbers: Verified Contacts, Hours, and Practical Tips

Primary Citibank customer care numbers (quick reference)

Citibank operates different customer care lines by country and product. The fastest way to reach the right team is to call the number printed on the back of your card or shown in your online/mobile banking profile. For convenience, here are widely used, verified hotlines for three major markets.

• United States (Citi credit cards): 1-800-950-5114. Available 24/7 for general card servicing, billing questions, payments, travel notices, and lost/stolen card support. Spanish-language support is available through the IVR. For TTY/TRS, dial 711 to connect via your state relay service and ask for Citi.
• India (Citi Cards, now serviced by Axis Bank): 1860-210-2484 (within India; standard local charges apply, not toll-free). From overseas: +91-22-4955-2484. These lines support Citi-branded credit cards, rewards, replacements, and transaction disputes. Available 24/7 for card emergencies.
• Singapore (CitiPhone Banking): +65 6225 5225. 24-hour hotline for credit cards and banking. Authentication typically uses your NRIC/FIN or card details and TPIN/OTP. International calling charges may apply if dialing from abroad.

Charges and coverage vary by carrier and location; use the mobile/online app for free in-app calling or callback options when available. Always confirm any number against the official site for your country (links provided below) or the back of your card, as contact details can be updated.

United States: how the Citi customer care line works

For U.S. cardmembers, the primary Citi customer care number is 1-800-950-5114, staffed 24/7. The interactive voice response (IVR) can recognize your phone if it’s on file and may authenticate you with a one-time passcode (OTP). From there, you can reach account specialists for payments, statement questions, balance transfers, credit limit reviews, travel notices, and disputes. Lost or stolen card options are prioritized in the IVR; reporting quickly helps block unauthorized transactions.

Have ready: the last 4 digits of your card, ZIP code, and a one-time passcode (via SMS/voice) for identity verification. If you use the Citi Mobile App, starting your call from within the app can speed authentication. For complex cases (e.g., fraud claims or chargebacks), ask the agent for a case reference number and the expected resolution timeline; keep your email/SMS notifications on to track updates.

If an issue needs escalation, ask to speak with a supervisor. Document the agent’s name, date/time, and each promised action. For written notices or formal correspondence, use the address shown on your monthly statement for your specific product; processing centers differ by card program and state, and using the wrong address can delay resolution.

India: Citi Cards and legacy Citibank India customers

Citibank’s consumer banking business in India was acquired by Axis Bank in 2022; Citi-branded credit cards continue to be serviced on dedicated Citi lines. Call 1860-210-2484 within India (local call rates; not toll-free) or +91-22-4955-2484 from overseas. These numbers handle card activation, PIN resets, reward redemptions, transaction disputes, EMI conversions, and emergency card blocking. Support is available 24/7 for card-related emergencies; general servicing hours can vary by queue.

When calling, keep your card’s last 4 digits and registered mobile number ready for OTP verification. If you’re traveling or reside abroad, the +91-22-4955-2484 line is the most reliable way to reach a Citi Cards specialist, but your international carrier may charge standard rates. You can also use the Citi Mobile app or web banking for many tasks (KYC updates, statements, and travel intimation) without waiting on hold.

Security reminder: neither Citi nor Axis will ask for your full card number, CVV, OTP, or to install remote-access apps during a support call. If you suspect fraud, hang up and redial the official number above or use the number on the back of your card. Report suspicious transactions immediately to maximize your chargeback rights.

Singapore: CitiPhone Banking hotline

In Singapore, the 24-hour CitiPhone hotline is +65 6225 5225. You will typically authenticate using your NRIC/FIN or card details plus a TPIN, or via an OTP sent to your registered mobile. The hotline supports cards and banking: limit reviews, payment assistance, fee queries, rewards, travel notices, and urgent card blocking. From outside Singapore, the same number works; international calling charges depend on your provider.

For fastest service, have your last 4 card digits and registered mobile accessible for OTPs, and call from your registered phone number when possible. Many common requests (e.g., card activation, e-statements, reward redemption) can be completed instantly in the Citi Mobile SG app, which can save time during peak call periods.

Best times to call and how to reduce wait time

Call volumes spike on Mondays, during lunchtime in each time zone, and in the first few business days after statement generation. You’ll typically experience shorter waits early mornings (e.g., 7–9 a.m. local time) or late evenings midweek. If your issue is non-urgent (e.g., a fee waiver review or address update), consider calling during off-peak hours or using secure messaging in the app or web banking.

Use in-app authentication and callback features when available; these can reduce time spent re-verifying your identity and keep your place in queue. Before calling, collect essential details: transaction dates/amounts, merchant descriptors, your case or reference number (if already opened), and any screenshots or PDFs of statements. Having this ready helps the agent resolve your case faster and limits back-and-forth.

Verify numbers and avoid scams

Only call numbers printed on your card, listed inside your signed-in Citi Mobile App, or shown on the official country website. U.S.: citi.com/contactus. India: citibank.co.in (which provides updated Citi Cards contacts) and axisbank.com/citi for post-acquisition service information. Singapore: citibank.com.sg/contactus. Ensure the URL uses HTTPS and the domain is exactly Citi’s (no extra words or misspellings).

Be wary of unsolicited calls or messages that pressure you to share one-time passcodes, full card details, or to install software. If someone contacts you claiming to be Citi, hang up and dial the official number yourself. For phishing SMS or emails, use the reporting tools in the Citi app or your email provider, and then contact Citi through the verified hotline to check your account activity.

Addresses and formal correspondence

Citigroup global headquarters: 388 Greenwich Street, New York, NY 10013, USA. This is not a servicing center; do not send payments or dispute letters here. For payments, disputes, and written notices, use only the mailing addresses shown on your monthly statement or within your secure online banking, as processing centers vary by product and geography.

Misdirected mail can delay resolution by a full billing cycle or more. If you’re unsure which address to use for a chargeback or formal complaint, ask the phone agent to read the exact address from your account profile and include your case number on all pages you send.

Alternatives to calling (often faster)

If you prefer not to wait on hold, Citi provides multiple digital channels that can resolve most tasks end-to-end. These options are also useful when traveling or if your phone line has poor connectivity.

• Citi Mobile App: Start in-app chat, request callbacks (where offered), activate cards, set travel notices, redeem rewards, dispute transactions, download statements, and update contact details with built-in authentication.
• Online banking: Use secure messaging to submit non-urgent requests; typical responses arrive within 1–2 business days. You can also schedule payments, set up autopay, and review fees before asking for a waiver.
• Branch or appointment (where available): Use the branch locator on your country site to schedule a visit for KYC updates, cashier’s checks, or complex account changes. Note that Citi has streamlined branches in some markets; check availability before you go.

Whichever channel you choose, capture confirmation numbers and save copies of any chats or messages. If your issue is time-sensitive (e.g., suspected fraud or a lost card), phone the hotline immediately and follow up with digital documentation as needed.
