Disputing charges with Citibank involves a formal process designed to investigate transactions you believe are incorrect, unauthorized, or problematic. The Fair Credit Billing Act (FCBA), a federal law passed in 1974, gives cardholders specific rights when disputing credit card transactions. Under this law, you have the right to dispute a charge within 60 days of when the charge first appears on your statement. Citibank must follow these federal requirements when handling your dispute, regardless of the reason you're questioning the charge.

When you initiate a dispute, Citibank launches an investigation into the transaction. During this time, the bank cannot report the disputed amount as late or delinquent on your credit report. The investigation period typically lasts 30 days, though Citibank can extend this to 90 days if they need additional time. Understanding this timeline is important because it affects both your account status and your credit profile during the dispute period.
The dispute process applies to several types of situations. These include charges you didn't authorize, charges that were processed twice (duplicate charges), charges for items or services you never received, charges for items or services that didn't match what the merchant described, mathematical errors on your statement, and unauthorized use of your card number. Each situation may have slightly different documentation requirements and investigation approaches.
Citibank handles disputes through their Disputes and Resolutions department. The bank employs trained representatives who review the evidence you provide and work with merchants to investigate claims. It's important to note that while the FCBA protects you during the dispute window, charges made after the 60-day window may still be disputable under other circumstances, such as if the merchant engaged in fraud or if you have additional evidence of a problem.
Practical Takeaway: Know the 60-day window from your statement date. Start gathering documentation immediately when you notice a problem, and don't wait until the last moment to file your dispute. The earlier you begin, the more time the investigation has to proceed.
Before you contact Citibank about a dispute, you need to clearly identify what went wrong. Taking time to document the problem thoroughly makes your dispute stronger and increases the likelihood of a successful outcome. Start by reviewing your statement carefully and comparing charges to any receipts, confirmation emails, or order records you have. Many people miss disputes simply because they don't notice the charge in the first place or assume a charge is legitimate when it actually isn't.

For unauthorized charges—transactions you didn't make—gather any evidence that you couldn't have authorized the charge. This might include proof that you were in a different location, evidence that your card was physically in your possession, or documentation showing that your account was compromised. For example, if your card number was used online but you never received the items, or if the charge occurred while your card was in a fraud freeze, this strengthens your case.
For items you ordered but didn't receive, keep all documentation from the purchase. This includes the original order confirmation, tracking information if available, and any communication with the merchant. If the merchant promised delivery by a certain date and never delivered, document those promises. Take screenshots of website pages showing what you ordered and what the merchant claimed the product was.
For items received but not as described, photograph or document how the item differs from what was advertised. If you ordered a specific color and received a different color, if you ordered one size and received another, or if you ordered a working product and received a damaged item, this constitutes a valid dispute reason. Save any communication with the merchant about the problem, including customer service emails or chat transcripts.
For duplicate charges, compare your statement to your receipts. Sometimes a transaction gets processed twice due to a technical error. Look for two identical or nearly identical charges on the same day or within a few days of each other. Document both the charges and the receipt, showing that only one transaction should have occurred.
Practical Takeaway: Create a simple document for your dispute file that lists the transaction date, amount, merchant name, what you ordered or expected, what actually happened, and what evidence you have. This organized approach helps when communicating with Citibank.
Filing a dispute with Citibank can be done through multiple channels, and you should choose the method that works best for your situation. The most direct method is through Citibank's online banking portal. If you have a Citibank credit card account and access to their website or mobile app, you can file a dispute from your account. Look for a "Disputes" or "Report a Problem" section, typically found in the transaction details or account settings area. When you access this section, you'll be asked to select the transaction you want to dispute and provide a reason for the dispute from a list of options.

You can also call Citibank's customer service line to file a dispute. The phone number appears on the back of your Citibank card and on your statement. When you call, have your account number, the disputed transaction details, and any supporting documentation ready to reference. The representative will walk you through the dispute form and may ask questions about the transaction. Request a case or dispute reference number when you file—this number allows you to track your dispute and reference it in future communications.
For written disputes, you can send a letter to Citibank's Disputes and Resolutions department. The address should be provided in your account materials or on the Citibank website. Send your letter via certified mail with return receipt requested so you have proof that Citibank received it. Include your account number, the disputed transaction details, the reason for the dispute, and copies of any supporting documents. Never send original documents—always send copies. Include a statement that you're disputing the charge under the Fair Credit Billing Act and request written confirmation of receipt.
When filing your dispute, you'll need to select a reason from Citibank's standard list. Options typically include "I don't recognize this charge," "I was charged twice," "The item didn't arrive," "The item wasn't as described," "Merchant error," and "Unauthorized use." Choose the reason that most accurately describes your situation. The reason you select may affect how Citibank investigates the dispute.
After you file, Citibank sends you a written acknowledgment of the dispute, usually within a few days. This communication includes your case number, the disputed amount, and the expected timeline for investigation. Keep this acknowledgment for your records. You may be asked to provide additional information during the investigation, and Citibank will contact you if they need clarification or more documentation.
Practical Takeaway: Use the method you're most comfortable with, but always get confirmation in writing. Keep all confirmation numbers, reference numbers, and correspondence from Citibank in one organized file so you can reference it throughout the process.
Once Citibank receives your dispute, they begin an investigation that involves contacting the merchant, reviewing transaction details, and examining any evidence you've provided. The investigation period is typically 30 days, though federal law allows up to 90 days in certain situations. During this time, the disputed amount is not considered late, and Citibank cannot report it as delinquent to credit agencies, even if you don't pay that portion of your bill.

Citibank's investigators look at several factors when reviewing your case. They examine the transaction details you provided, compare it to the merchant's records, review any communications between you and the merchant, and assess the strength of your evidence. For unauthorized charges, they determine whether your account showed signs of fraud and whether the charge matched your typical spending patterns. For undelivered items, they may contact the merchant to ask for tracking information or delivery confirmation. For items not as described, they may ask the merchant for details about what was shipped and compare that to what they advertised.
The merchant also has an opportunity to respond to your dispute. They may provide proof of delivery, proof that you authorized the charge, bank transaction records, or other documentation. In some cases, merchants will work with Citibank to resolve the issue by issuing a refund directly, which happens before the investigation concludes. If the merchant doesn't respond to Citibank's inquiry, this weighs in your favor, as it can indicate the merchant is unable or unwilling to defend the charge.
