Learn How to Dispute Unauthorized Credit Card Charges

Understanding Unauthorized Credit Card Charges

An unauthorized credit card charge is any transaction made on your account without your permission. This might include fraudulent purchases made by someone who stole your card information, charges made by a family member without consent, or errors by merchants who charged you twice. Understanding what counts as unauthorized is the first step in the dispute process.

Unauthorized charges happen more frequently than many people realize. According to the Federal Trade Commission, credit card fraud affected millions of consumers in recent years, with cases ranging from small duplicate charges to large purchases made across the country. The good news is that federal law provides protections when these charges occur on your credit card account.

It's important to distinguish between truly unauthorized charges and legitimate charges you might not immediately recognize. Sometimes charges appear under unfamiliar merchant names, or you might forget about a subscription service you signed up for months ago. Checking your statements regularly helps you identify genuine fraudulent activity versus charges you actually made. Many people discover unauthorized charges when they review their monthly statements or receive alerts from their card issuer.

The Fair Credit Billing Act (FCBA) is the federal law that governs how credit card companies must handle disputes over unauthorized charges. Under this law, your liability for unauthorized charges is generally limited to $50, though most card issuers offer zero-liability protection, meaning you won't be responsible for fraudulent charges at all. This protection applies to credit cards and some debit cards linked to checking accounts, though the rules vary slightly depending on the card type.

Practical takeaway: Review your credit card statements monthly, either through paper statements or online accounts. Set up transaction alerts through your card issuer's app or website so you're notified of charges in real-time. This allows you to spot unauthorized activity quickly and report it before additional fraudulent charges occur.

Spotting Unauthorized Charges on Your Statement

Recognizing unauthorized charges requires careful attention to your monthly statements. Many fraudulent charges are small amounts that people overlook, especially if they're reviewing statements quickly. Scammers sometimes test stolen card information with small purchases of one or two dollars before making larger purchases. Learning to read your statement thoroughly is essential for early fraud detection.

When reviewing your statement, check several things carefully. First, look at the merchant names and descriptions. Sometimes fraud appears under company names you don't recognize, but other times the merchant name might be abbreviated or show a parent company rather than the store where you think you shopped. Second, verify the transaction amounts match what you remember spending. Third, check the dates to make sure purchases occurred when you actually used your card. Fourth, look for duplicate charges for the same amount on the same date, which could indicate a processing error.

Some charges may seem suspicious but turn out to be legitimate. For example, subscription services might renew automatically, or a company might use a business name different from their customer-facing brand. A charge from a hotel or rental car company might appear days after your transaction was completed because these businesses sometimes hold the charge initially and then settle it later. Before assuming a charge is fraudulent, try to recall if you made the purchase or authorized it.

Certain red flags suggest a charge is likely unauthorized. These include transactions from locations you never visited, charges for products or services you never ordered, transactions during times when you know you didn't use your card, charges from foreign countries when your card was physically in your possession, or multiple small charges that appear to be testing your card's validity. If you see your full card number or expiration date listed in plain text on a statement, that's also concerning and worth reporting to your card issuer immediately.

Your card issuer may also send you a fraud alert if their monitoring systems detect suspicious activity. These alerts don't always mean fraud has occurred—sometimes legitimate travel or large purchases trigger them—but they're worth investigating. Contact your issuer through the phone number on the back of your card to verify whether the transaction was authorized.

Practical takeaway: Set a monthly reminder to review your statements. Create a simple spreadsheet or use your card issuer's budgeting tools to track your spending categories, which makes spotting unusual charges easier. If you notice anything questionable, don't wait—contact your card issuer within 60 days to preserve your dispute rights.

Steps to Dispute Unauthorized Charges with Your Card Issuer

Once you've identified an unauthorized charge, the next step is contacting your card issuer to begin the dispute process. Time matters significantly in credit card disputes. Federal law requires that you report the unauthorized charge within 60 days of receiving your statement for the dispute protections to apply fully. Most card issuers have even shorter timeframes they recommend, often 30 days or less, though they may still investigate claims made after that period.

Start by gathering documentation about the disputed transaction. Write down the transaction date, amount, merchant name, and a description of why you believe it's unauthorized. If you have any related documents—such as emails from the merchant, receipts for what you actually purchased, or correspondence about the dispute—keep these organized and accessible. If someone stole your card, note the date you discovered it was missing and when you first reported it.

Contact your card issuer through the customer service number on the back of your card or through their website. Many card issuers now allow you to start disputes through their mobile app or online account portal, which creates a written record of your claim. If you call, ask the representative to confirm the dispute in writing and provide you with a reference number. During the call, clearly explain which transaction is unauthorized, when you first noticed it, and what you've done to resolve the issue (if anything).

When explaining the unauthorized charge, be specific and factual. Rather than saying "I don't recognize this," explain what makes it unauthorized: "I did not make this purchase," "I did not give permission for this charge," "This merchant was not authorized to charge my card," or "I reported my card stolen on [date] and this charge occurred after that date." Card issuers have procedures for different types of disputes, and being clear helps them categorize your claim correctly.

After you report the dispute, your card issuer will typically conduct an investigation. During this time, you shouldn't be responsible for paying the disputed amount. Many card issuers will credit the disputed amount to your account temporarily while they investigate, though this varies by issuer. The investigation usually takes 30 to 90 days. Your card issuer may contact the merchant to ask whether they can verify the transaction and confirm it was authorized. The merchant has an opportunity to provide evidence that you authorized the charge.

Practical takeaway: Document everything in writing. Save emails, reference numbers, and the names of representatives you speak with. Create a simple timeline showing when you discovered the unauthorized charge and when you reported it. Keep this documentation for at least one year in case you need to reference it later.

What Happens During the Card Issuer's Investigation

Understanding what occurs while your card issuer investigates helps you know what to expect and how long the process takes. The investigation process is governed by the Fair Credit Billing Act, which sets specific timelines and procedures that card issuers must follow. Your card issuer must acknowledge your dispute in writing within 30 days of receiving your complaint and must complete the investigation within two billing cycles (but no more than 90 days).

During the investigation, your card issuer contacts the merchant's bank (called the acquiring bank) with information about the disputed transaction. The merchant's bank then asks the merchant to respond. The merchant must provide evidence that the transaction was authorized and valid. This might include a signed sales receipt, an authorization code from the transaction, IP address information showing where the purchase was made, the delivery address, or other documentation showing the purchase was legitimate.

You may be asked to provide additional information during the investigation. Your card issuer might request a written statement from you describing the unauthorized charge, documentation of any prior contact with the merchant about the issue, police reports if the card was stolen, or other evidence supporting your claim. Responding quickly to these requests helps move your investigation forward. If the card issuer can't reach you to ask clarifying questions, they may resolve the dispute against you.

The investigation can result in different outcomes. Your card issuer may rule in your favor, meaning they determine the charge was truly unauthorized and credit your account permanently. They may rule against you, meaning they conclude you authorized the charge or the merchant provided sufficient proof of authorization, and you're responsible for paying it. Or the investigation may be inconclusive, in which case the card issuer follows specific procedures about how to resolve it.

If your card issuer rules against you in the investigation, you have options. You can request a copy of the
