Chase Credit Card Fraud Number: How to Report Fraud and What Happens Next

Discovering unauthorized charges on your Chase credit card can feel alarming. Knowing exactly where to call, what to expect, and how the fraud resolution process works can make the difference between a stressful ordeal and a swift recovery. Here's what you need to know.

The Chase Credit Card Fraud Phone Number

The primary number to report Chase credit card fraud is 1-800-432-3117, available 24 hours a day, 7 days a week. This line connects you directly to Chase's fraud department, where a representative can freeze your account, dispute unauthorized charges, and issue a replacement card.

You can also find this number on the back of your Chase credit card — a good habit is to save it in your phone before you ever need it.

Additional ways to reach Chase for fraud:

• Chase Mobile App: Tap "Secure messages" or use the "Report fraud" option directly within the app
• Chase.com: Log in, navigate to your account, and select "Report unauthorized transactions"
• In-branch: Any Chase branch can initiate a fraud report, though the phone line or app is typically faster

What Counts as Credit Card Fraud?

Not every billing surprise is fraud, and knowing the difference helps you report accurately.

Fraud typically includes:

• Charges you did not make and did not authorize
• Purchases appearing after your card was lost or stolen
• Account takeover — someone changed your login credentials or opened accounts in your name
• Skimming — your card data was copied and used without your physical card being stolen

Not fraud, but still disputable:

• A merchant charged you incorrectly
• You were billed for a subscription you canceled
• Goods or services you paid for weren't delivered

The second category falls under a billing dispute rather than a fraud claim, and Chase handles each through slightly different processes. When you call, the representative will help clarify which path applies.

What to Expect When You Call 📞

The fraud reporting call typically moves through several steps:

1. Verification — Chase will confirm your identity using your Social Security number, date of birth, account number, or other identifying details. This protects you from someone else fraudulently "reporting fraud" to take over your account.

2. Transaction review — A representative walks through the suspicious charges with you. You'll confirm which transactions are yours and which are not.

3. Temporary freeze or card cancellation — Chase will typically freeze the compromised card immediately. In most cases, they'll send a replacement card within a few business days, though expedited delivery is often available.

4. Provisional credit — For fraud claims, Chase frequently issues a provisional (temporary) credit while the investigation is underway. This means the disputed amount is returned to your available balance while Chase investigates, which can take up to 10 business days in standard cases.

5. Investigation outcome — Chase investigates the claim, often reviewing transaction data, merchant records, and patterns. If the fraud is confirmed, the credit becomes permanent. If Chase determines the charge was legitimate, they may reverse the provisional credit and provide an explanation.

Your Rights Under Federal Law

The Fair Credit Billing Act (FCBA) limits your liability for unauthorized credit card charges to $50 — and most major issuers, including Chase, have a $0 fraud liability policy, meaning you typically won't owe anything for confirmed unauthorized charges.

This protection only applies to credit cards, not debit cards, which is one reason many financial professionals recommend using a credit card for everyday purchases over a debit card. With debit cards, the liability window and coverage rules differ significantly under the Electronic Fund Transfer Act (EFTA).

How Chase's Fraud Detection Works

Chase uses automated systems that monitor transactions in real time for unusual patterns — purchases in an unfamiliar city, a sudden spike in high-value transactions, or charges at merchants inconsistent with your spending history. 🔍

When Chase flags a suspicious charge before you do, they may:

• Send a text or push notification asking you to confirm the transaction
• Temporarily decline a charge and ask you to verify it
• Place a hold on your account until you respond

These alerts are why keeping your contact information current with Chase matters. If your phone number is outdated, you may miss a real-time fraud alert that could stop a charge before it clears.

Protecting Yourself Before Fraud Happens

Proactive steps that reduce your fraud risk:

Chase offers virtual card numbers through its browser extension for select cards, which generates a temporary card number for online purchases — so your real number is never exposed to a merchant's database.

How Fraud Affects Your Credit Profile

A fraud investigation itself does not hurt your credit score. However, unresolved fraud can — particularly if fraudulent accounts are opened in your name, leading to missed payments, high balances, or hard inquiries you didn't authorize. This is why reporting quickly and following up matters.

If fraud has already appeared on your credit reports, you have the right to place a fraud alert or credit freeze with the three major bureaus — Equifax, Experian, and TransUnion — at no cost. A fraud alert lasts one year; a freeze remains until you lift it.

The Part That Varies by Situation

How disruptive a fraud incident becomes — and how smoothly resolution goes — depends on factors specific to your account: how quickly you reported it, whether the charges are still pending or have posted, your history with Chase, and whether identity theft extended beyond your credit card to other accounts.

Two cardholders can report fraud on the same day and experience meaningfully different timelines depending on these details. Your account history, the nature of the charges, and how far the fraud may have spread are the variables that shape what comes next for you specifically.
