How to Dispute an Unauthorized Credit Card Charge in California: What Federal Law Actually Gives You
How long do I have to dispute an unauthorized credit card charge?
Under the federal Fair Credit Billing Act, you generally have 60 days from the date your statement was mailed to submit a written dispute to your card issuer. That clock starts from the statement date, not the transaction date, so it's worth checking your statement as soon as it arrives. Waiting past 60 days can waive your FCBA protections.
Does calling my credit card company count as filing a dispute under federal law?
A phone call alone does not fully trigger your rights under the Fair Credit Billing Act. The law requires written notice sent to the address your issuer designates for billing inquiries, which is often different from the payment address on your statement. Many issuers also accept disputes through their app or website, but a written letter sent by certified mail creates the clearest legal record.
Can I dispute a credit card charge for something I bought but was unhappy with?
Yes, but with conditions. The Fair Credit Billing Act allows disputes over goods or services that were not delivered as agreed, but for quality-based disputes the purchase typically must exceed $50 and must have been made in your home state or within 100 miles of your billing address. Unauthorized charges - someone used your card without permission - don't carry these geographic or dollar restrictions.
Where do I report a credit card billing dispute that my bank refused to fix in California?
California consumers can file a complaint with the California Department of Financial Protection and Innovation at dfpi.ca.gov if their card issuer failed to properly handle a dispute. You can also submit a complaint to the federal Consumer Financial Protection Bureau at consumerfinance.gov. Neither complaint guarantees a refund, but both create a regulatory record that may prompt the institution to reconsider.
What's the difference between a fraud alert and a credit freeze in California?
A fraud alert requires creditors to take extra steps to verify your identity before opening new credit in your name; it's free and lasts one year under federal law, though extended alerts are available for confirmed identity-theft victims. A credit freeze goes further by blocking new credit from being opened entirely until you lift it. Both are free under federal law and are available through each of the three major credit bureaus.
An unfamiliar charge on your credit card statement - whether it's a $9.99 subscription you never signed up for or a fraudulent purchase made after your card number was stolen - is something California consumers can formally dispute, often with a legal right to a full refund. The process is more structured than most people realize, and knowing the actual rules makes a big difference in whether you get your money back.

The Federal Law Behind Your Dispute Rights
Your core protection comes from the federal Fair Credit Billing Act, which applies to all credit cards nationwide. Under the FCBA, you can dispute a charge on your credit card statement that you believe is unauthorized (meaning you didn't make it or authorize it), is for goods or services you didn't receive, or reflects a billing error. The law requires your card issuer to acknowledge your dispute in writing within 30 days and resolve it within two complete billing cycles, not to exceed 90 days. During that window, the issuer generally cannot try to collect the disputed amount or report it to credit bureaus as delinquent.
California consumers also have state-level backup through the Consumers Legal Remedies Act and the Unfair Competition Law, which give the state attorney general and private individuals broader tools to go after deceptive billing practices - but for the mechanics of getting a single charge reversed, the FCBA is what you're actually working with day to day.
What Counts as a Disputable Charge
The FCBA distinguishes between two categories. The first is a billing error: a charge you didn't authorize, a transaction for the wrong amount, a charge for something you returned or never received, or a charge for goods or services not delivered as agreed. These get the full FCBA dispute process and the strongest consumer protections. The second category covers disputes about the quality of goods or services - for example, a merchant who delivered something but you believe it was defective. Those disputes have an additional hurdle: the purchase generally must have been made in your home state or within 100 miles of your current billing address, and for more than $50. Credit card issuers sometimes waive these geographic and dollar limits as a matter of policy, but they're not legally required to.
Unauthorized charges - someone used your card number without your permission - fall cleanly into the billing-error category and don't carry the geographic or dollar restrictions.
How to File the Dispute
The FCBA requires you to submit your dispute in writing to the address the issuer designates for billing inquiries, which is often different from where you mail your payment. Check your statement carefully - it's typically labeled "billing inquiries" or "send correspondence to." Calling your card issuer is a reasonable first step to freeze a fraudulent charge quickly, but a phone call alone does not trigger your full FCBA protections. Follow it up in writing.
Your written dispute should include your name, account number, the date and amount of the charge you're disputing, and a brief explanation of why you believe it's an error. Send it by certified mail with a return receipt if you can - that gives you a dated paper trail. Under the FCBA, your written dispute must reach the issuer within 60 days of the date the statement containing the disputed charge was mailed to you. That 60-day window is strict, so don't sit on it.
Many major issuers also accept disputes through their online portal or mobile app, and some explicitly extend FCBA-equivalent treatment to those electronic submissions - but the law's written-notice requirement is clearest with an actual letter, so if the charge is large or the situation is complicated, go with a letter.
What Happens After You Dispute
Once the issuer receives your dispute, it must investigate and either correct the error or explain in writing why it believes the charge is valid. You're entitled to copies of any documentation the issuer relies on in its decision. If the issuer sides with the merchant and you disagree with that outcome, you can request the documents they used and submit additional evidence of your own - receipts, correspondence with the merchant, screenshots of a cancellation confirmation, whatever is relevant.

If your dispute is resolved in your favor, the issuer must remove the charge and any associated interest or fees. If it's resolved against you and you still believe the charge is wrong, you can note in writing that you dispute the finding, which must be reflected in any future credit reporting on that account. At that point, you may also want to file a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov or with the California Department of Financial Protection and Innovation, which oversees state-chartered financial institutions and some other financial service providers.
California-Specific Leverage
California's Department of Financial Protection and Innovation, or DFPI, has jurisdiction over many financial companies doing business in the state and can receive complaints about billing disputes that weren't handled fairly. Filing a DFPI complaint won't automatically get your money back, but it creates a formal record and puts the institution on notice that a regulator is aware of the situation - which sometimes prompts a faster resolution. The DFPI accepts complaints online at dfpi.ca.gov.
Separately, if you believe you were the victim of outright fraud - a scammer obtained your card number through a phishing scheme, a data breach, or identity theft - you should also file a report with the California Attorney General's office and consider placing a fraud alert or credit freeze with the three major credit bureaus. A fraud alert is free and requires creditors to take extra steps to verify your identity before opening new accounts; a credit freeze goes further and blocks new credit from being issued in your name entirely. Both are free under federal law.
This is general information, not legal or financial advice. Dispute rules, timelines, and the specific procedures your card issuer requires can vary, and the FCBA's requirements are set by federal statute and regulation that may be updated. Verify current rules with the Consumer Financial Protection Bureau at consumerfinance.gov, and for California-specific complaints or questions, contact the California Department of Financial Protection and Innovation at dfpi.ca.gov.
