CBNA Customer Service Number — Expert Guide to Finding and Using the Right Contact

What “CBNA” means and why it appears on your statement

CBNA is most commonly an abbreviation that appears on transaction descriptors and issuer records for Citibank, N.A. (Citibank is the retail banking arm of Citigroup). If you see “CBNA” or “CBNA CARD SERVICES” on a charge, it typically identifies Citibank as the card issuer or processor for that merchant or card network. Recognizing the acronym is the first step to resolving questions about billing, returns or fraud alerts.

Because multiple banks and servicers can appear with similar short codes, always confirm the issuer by checking the full card name on your monthly statement or the issuer name printed on the physical card. In many cases the card back, the printed statement header, or the email from the issuer will explicitly say “Citibank, N.A.” or similar, which removes ambiguity when you look up the correct customer service channel.

Where to find the official customer service number

The only reliable sources for an issuer’s customer service number are (1) the back of your card, (2) the printed or PDF statement issued to you, and (3) the issuer’s official website. For Citibank (the organization commonly abbreviated CBNA), the primary consumer website is https://www.citi.com and corporate headquarters is listed at 388 Greenwich Street, New York, NY 10013. Use those official sources to avoid fraudulent phone numbers.

If you cannot access your card or statement, log in to the secure account portal at https://www.citi.com, open the account details page and look for the “Contact us” or “Customer service” link. Many issuers place a direct phone number, secure message link and mailing address there. When calling from outside the United States, the portal will display the appropriate international dialing number and any country-specific hours.

What to have ready and when to call

Before calling customer service about a CBNA-related charge, prepare: your full account number or last 4 digits, the exact transaction date(s), merchant name and posted amounts (e.g., $123.45 on 2025-08-01), and any relevant receipts. Also note whether the card was present or used online, and whether you have previously disputed the charge with the merchant. Having these specifics reduces hold time and speeds dispute resolution.

Use the customer service number for different purposes depending on urgency. For lost or stolen cards and suspected fraud, call immediately — most issuers operate 24/7 lost-card lines. For billing disputes, reward inquiries, balance/payments or interest-rate questions, call during normal customer-service hours (often 8:00–22:00 local time Monday–Friday). If your matter requires a written record, follow up with a secure message inside your online account or send correspondence to the corporate mailing address.

How to verify a CBNA number is legitimate and protect yourself from scams

Scammers use realistic-sounding numbers and spoof Caller ID. Never rely solely on the number shown by an incoming call. Instead, hang up and call the number printed on your card or the number listed in your online account at citi.com. Confirm the representative’s name, employee ID and the reason for the call before sharing personally identifiable information. If a caller pressures immediate payment via unusual channels (gift cards, wire transfers, cryptocurrency), treat it as a scam and terminate the call.

Additional verification steps: check the secure site’s SSL certificate (browser padlock), confirm account-specific data (last payment amount or last 4 digits of a linked account), and request a written confirmation by secure message. If you suspect fraud after a call, request a written case number and the supervisor’s contact — reputable banks will supply these and will not require payment to open a fraud investigation.

Quick checklist: where to look right now

• Back of your physical card — the primary phone number printed there is the definitive contact for that specific account.
• Monthly paper or PDF statement — the contact number for billing disputes and secure mailing address appears on the statement header or “Contact” section.
• Secure online account at https://www.citi.com — displays country-specific customer service numbers, secure messaging and dispute initiation tools.
• Corporate mailing address for escalations: Citigroup Inc., 388 Greenwich St, New York, NY 10013; include account number and copies of supporting docs.

Practical timings, expected wait times and escalation

Lost/stolen card hotlines are generally staffed 24/7 and should answer within minutes; expect a short verification process (2–10 minutes). For routine customer service calls (payments, disputes, rates), average hold times vary by time of day and season: typical windows are 5–25 minutes, but during major disruptions or holidays waits can extend to 45+ minutes. Request a callback if the option exists — it preserves your place in queue and avoids repeated authentication.

If frontline service cannot resolve your issue, ask for a supervisor or for the “escalation” or “special investigations” team. For disputes that are not resolved within the issuer’s stated timeline, you can file a written complaint with Citigroup’s designated office (use the corporate mail address above) and, if necessary, escalate to a consumer protection agency such as the Consumer Financial Protection Bureau (CFPB) in the U.S. — their complaint portal is at https://www.consumerfinance.gov/complaint/.
