How to Dispute an Unauthorized Credit Card Charge in California
How long do I have to dispute an unauthorized credit card charge in California?
Under the federal Fair Credit Billing Act, you generally have 60 days from the date the billing statement containing the disputed charge was mailed to you to submit a written dispute to your credit card issuer. California law does not extend this federal deadline, so acting quickly after you spot an unfamiliar charge is important.
Does disputing a credit card charge hurt your credit score?
Disputing a credit card charge under the Fair Credit Billing Act should not hurt your credit score. While the dispute is under investigation, your issuer cannot report the disputed amount as delinquent to credit bureaus. However, if the investigation closes against you and you then fail to pay the amount, that non-payment could eventually affect your credit.
What's the difference between disputing a charge and reporting fraud?
Disputing a charge is a formal process with your credit card issuer to investigate a billing error or unauthorized transaction, governed by the Fair Credit Billing Act. Reporting fraud to authorities, such as the California Attorney General or the FTC at reportfraud.ftc.gov, is a separate step that helps build enforcement cases against merchants or scammers but does not directly resolve your individual charge.
Can I dispute a credit card charge made by someone else in my household?
You can dispute a charge as unauthorized only if the person who made it was not an authorized user on your account. If someone you added to your account made the charge, that is generally not considered unauthorized under the Fair Credit Billing Act, even if you didn't approve that specific purchase. The distinction between an authorized user and account fraud matters significantly here.
Who do I complain to if my credit card company won't resolve my dispute in California?
California residents can file complaints with two agencies. The Consumer Financial Protection Bureau at consumerfinance.gov/complaint handles complaints against credit card issuers nationwide and routes them directly to the company for a required response. The California Department of Financial Protection and Innovation at dfpi.ca.gov handles complaints about state-regulated financial institutions specifically. For merchant fraud, the California Attorney General's office at oag.ca.gov also accepts consumer complaints.
An unfamiliar charge on your credit card statement can mean anything from a merchant billing error to outright fraud. Under both federal law and California consumer protections, cardholders have a defined process for disputing those charges, and credit card issuers are legally required to investigate. Knowing the rules before you call your bank can make a significant difference in how quickly you get your money back.

Your Federal Baseline: The Fair Credit Billing Act
Most of the mechanics here start with the federal Fair Credit Billing Act, which applies to all credit card accounts in the United States. The FCBA covers unauthorized charges, charges for goods or services you never received, and billing errors. It does not cover debit card disputes, which fall under different rules, so confirm you're looking at a credit card statement before assuming these protections apply.
The most important deadline: you generally have 60 days from the date the statement containing the disputed charge was mailed to you to submit a written dispute. That 60-day clock is strict. If you miss it, your issuer isn't legally required to investigate under the FCBA, though many will still work with you as a customer-service matter. The charge amount typically has to exceed one dollar to trigger FCBA protections, and the billing error must appear on a statement, not just a pending transaction.
Once your issuer receives a written dispute, federal rules require them to acknowledge it within 30 days and resolve it within two billing cycles, but no more than 90 days. During the investigation, you're not required to pay the disputed amount, and the issuer can't report that amount to credit bureaus as delinquent while the dispute is open.
California's Added Layer: The Rosenthal Act and State Law
California's Rosenthal Fair Debt Collection Practices Act and the state's broader consumer protection framework don't directly govern the chargeback process itself, but they do matter if things go sideways. If your bank or a third-party debt collector tries to collect a disputed amount while an investigation is pending, or uses deceptive or harassing tactics, those actions may violate California law independently of whether the original charge dispute gets resolved in your favor.
California's Unfair Competition Law, enforced by the California Department of Justice and the state Attorney General's office, also gives consumers a path to report banks or merchants who engage in systematically deceptive billing practices, not just your individual dispute. If you believe a merchant is running a fraudulent scheme that affects other consumers, filing a complaint with the California Attorney General's office at oag.ca.gov is a separate and useful step.
How to Actually File the Dispute
Start with a phone call to the number on the back of your card, but don't stop there. Federal law requires your dispute to be in writing to fully trigger FCBA protections. Send a written dispute letter by certified mail, return receipt requested, to the billing inquiries address on your statement, which is often different from your payment address. Keep a copy of the letter and the mailing receipt.
Your letter should include your name, account number, the date and amount of the disputed charge, the name of the merchant, and a brief explanation of why you're disputing it. You don't need to prove fraud at this stage; you just need to identify the charge and assert that it's an error. If you have supporting documents, such as a receipt showing a different amount or a cancellation confirmation, include copies, not originals.
Many issuers now let you initiate disputes through an app or online portal. That's fine as a starting point, but if the charge is large or the issuer is unresponsive, follow up with a written letter anyway. The FCBA's protections technically attach to written notice; a phone call or app submission may or may not meet that bar depending on your issuer's policies.
What Happens During the Investigation
Your issuer will typically issue a provisional credit to your account while they investigate, especially in clear-cut fraud cases. This isn't a final resolution; if the investigation closes in the merchant's favor, the provisional credit gets reversed. That reversal notice should come in writing, and you'll have another opportunity to provide additional documentation if you disagree with the outcome.

If the dispute involves fraud, your issuer will also likely cancel your existing card number and issue a new one. Check any automatic payments or subscriptions tied to the old number and update them.
If Your Issuer Won't Help
If your credit card company denies your dispute and you believe they mishandled the investigation, you have several options. You can file a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov/complaint, which routes complaints directly to the financial institution and requires a response. The CFPB's complaint database is public, and issuers take it seriously.
For California-specific issues, the California Department of Financial Protection and Innovation (DFPI) regulates many state-chartered banks and financial services companies operating in California. You can file a complaint at dfpi.ca.gov. For fraud by a merchant specifically, the California Attorney General's office accepts consumer complaints at oag.ca.gov. Neither agency will litigate your individual dispute, but complaints build the record that triggers enforcement actions against companies with patterns of bad behavior.
If the amount at stake is significant and you believe the issuer violated the FCBA, consulting a consumer law attorney is worth considering. California has attorneys who take consumer protection cases on contingency, and the FCBA provides for recovery of attorney fees if you prevail.
