When you spot an unauthorized or incorrect charge on your Citibank credit card statement, you have legal protections under the Fair Credit Billing Act (FCBA). This federal law gives cardholders the right to dispute charges and requires credit card companies to investigate your claim. Understanding these rights is the foundation of the dispute process.

The FCBA covers several types of disputes. Unauthorized charges occur when someone uses your card without permission. Billing errors include charges for items you didn't receive, duplicate charges, charges with incorrect amounts, and charges posted to your account on the wrong date. The law also covers situations where a merchant fails to credit your account after you return merchandise or cancel a service.
Your rights extend beyond just filing a dispute. During the investigation period, you don't have to pay the disputed amount. Citibank must acknowledge your dispute within 30 days and complete the investigation within two billing cycles (typically 60 days). The bank must either resolve the dispute or explain why the charge was valid. If Citibank determines the charge was correct, they must provide documentation supporting their decision.
The FCBA also protects you from penalties while a dispute is pending. Citibank cannot close your account, reduce your credit limit, or report you as delinquent based solely on the disputed amount. However, you remain responsible for paying undisputed portions of your bill to maintain your account in good standing.
Understanding these legal protections helps you approach disputes confidently. You're not asking for a favor—you're exercising rights that federal law provides. This knowledge shapes how you document disputes and what you can expect from Citibank throughout the process.
Practical Takeaway: Review your Citibank statements regularly within the first 60 days of billing to catch errors while your dispute rights are strongest. Keep documentation of all transactions and communications with merchants.
Before you file a dispute, you need to accurately identify whether a charge is truly fraudulent, erroneous, or something else. This distinction matters because it affects how Citibank investigates and what information you'll need to provide. Fraudulent charges result from unauthorized use of your card. Erroneous charges result from merchant mistakes or system errors. These require different dispute approaches.

Fraudulent charges typically fall into categories. Card-present fraud occurs when someone physically uses your card or a counterfeit card. Card-not-present fraud happens when someone uses your card number for online, phone, or mail purchases. Account takeover fraud involves someone gaining access to your online account and making purchases or changes without your knowledge. Identity theft represents the most serious form, where someone uses your personal information to open accounts or make large purchases.
Erroneous charges come from different sources. A merchant might charge you twice for a single transaction due to a processing error. You might be charged for merchandise you returned but didn't receive a credit. A subscription service might continue charging you after you requested cancellation. A merchant might have charged you an incorrect amount than what was agreed upon. These merchant-caused errors account for a significant portion of legitimate disputes.
To identify the type of charge, review your purchase records. Check your email confirmations, receipts, and credit card statements. If you recognize the merchant but don't remember the purchase, contact the merchant directly before filing a dispute—many issues resolve this way. If you don't recognize the merchant at all, search online for the company name or look up the phone number associated with the charge. Sometimes merchants use different business names on statements than they use publicly.
Watch for patterns that suggest fraud. Multiple small charges from unfamiliar companies might indicate card-not-present fraud. Charges from locations you've never visited suggest card fraud. Charges while you're away from home on a different continent clearly indicate fraudulent use. These patterns help Citibank understand the nature of your dispute.
Practical Takeaway: Before disputing, attempt to contact the merchant directly about questionable charges. Document the merchant's response or lack of response, as this information supports your dispute claim.
The process of disputing a charge with Citibank involves several formal steps. The bank requires specific information and follows a structured timeline. Knowing these steps helps you navigate the process efficiently and ensures Citibank properly investigates your claim.

Your first step is to contact Citibank within 60 days of the charge appearing on your statement. This deadline is critical—the FCBA protects your dispute rights only within this window. You can reach Citibank through multiple channels. Call the customer service number on the back of your card or visit a local Citibank branch in person. You can also use the online chat feature or submit a dispute through your online account portal. Online submission often provides documentation you can reference later.
When you contact Citibank, have your account information and the specific charge details ready. Provide the transaction date, merchant name, charge amount, and a clear explanation of why you're disputing it. Be concise but specific. Say "I don't recognize this merchant and did not authorize this charge" rather than vague statements like "this doesn't look right." For erroneous charges, explain what went wrong—whether it's a duplicate charge, wrong amount, or undelivered merchandise.
Citibank will ask you to document your dispute in writing. You can do this through their online portal, through email, or by mailing a letter. Include your account number, the transaction details, and your explanation. If you've already contacted the merchant, mention that in your written dispute. Attach any supporting documentation—email confirmations, receipts, correspondence with the merchant, or proof of return for merchandise.
After you submit your dispute, request confirmation that Citibank received it. This confirmation should include a reference number for tracking. Save this reference number and all documentation in a file you can access later. Citibank will send you written acknowledgment of your dispute within 30 days, typically by mail or through your online account.
During the investigation period, Citibank may request additional information. Respond promptly to these requests. If they ask for proof of return, provide tracking numbers and receipts. If they ask for communication with the merchant, provide copies of emails or notes about phone conversations. The more documentation you provide, the stronger your dispute becomes.
Practical Takeaway: File your dispute through Citibank's online portal when possible so you have immediate written confirmation. Save the reference number and take screenshots of your submission for your records.
The quality of your documentation often determines the outcome of your dispute. Citibank bases their investigation on the evidence you and the merchant provide. Understanding what types of evidence matter helps you build a strong case.

For unauthorized charges, gather evidence that you didn't make the purchase. This includes your statement showing you were in a different location when the charge occurred, shipping records showing delivery to an address you don't recognize, or testimony that you discovered your card was stolen or lost. If your card was compromised online, screenshots of your account's login history showing access from locations you didn't visit can support your claim. For card theft, a police report adds weight to your dispute, though it's not required.
For duplicate charges, provide documentation showing the charge appears twice on your statement with identical or near-identical amounts within a short timeframe. Your payment confirmation email from the merchant showing a single authorization but two charges appearing helps prove this was a processing error. If you paid the merchant multiple ways (card and bank transfer, for example), clarify that you only intended one payment.
For undelivered merchandise, collect shipping confirmation and delivery tracking. If the package shows delivered but you never received it, that's significant. Photos of your mailbox or front door showing nothing was delivered strengthen this claim. If you contacted the merchant requesting a refund or replacement, save those emails. If the merchant acknowledged the non-delivery and promised a refund, that communication is crucial evidence.
For returned merchandise, keep your return shipping receipt and tracking number. If the merchant provided a return authorization number, save that. Email confirmations showing the merchant received the return and promised a credit within a timeframe are valuable. If the merchandise arrived damaged or defective and the merchant confirmed this, that documentation supports your dispute claim. Many merchants provide photos upon receipt—request a copy showing your returned item arrived at their facility.
