After you report suspected credit-card fraud, the issuer records the claim, may block and replace the card, investigates whether the transaction was unauthorized, and sends a decision or account adjustment. Federal law generally limits liability for unauthorized credit-card use to $50 when statutory conditions are met, but there is no single federally mandated investigation time or temporary-credit schedule for every credit-card claim. Report promptly, follow up in writing, and keep a complete record.
What the issuer does first
The process starts when you notify the card issuer through its app, website, phone service, or another channel it provides. Tell the issuer which transaction you dispute, when you noticed it, and whether the physical card is missing. The Consumer Financial Protection Bureau (CFPB) advises monitoring accounts closely, reporting suspicious activity, and keeping records. The Federal Trade Commission (FTC) recommends following a phone or app report with written notice and retaining a copy.

Record the report
Write down the date and time, the channel used, the representative or department, the disputed amount and merchant, and any confirmation or case number. Ask where a written billing-error notice must be sent; the address may differ from the address used for payments and is usually printed on the statement. Save screenshots, emails, letters, forms, and the statements showing the charge.

Expect possible card blocking or replacement
An issuer may block the compromised card and issue a new number. The CFPB recommends canceling and replacing a card when suspicious activity is detected, but federal sources do not establish one required sequence or a universal delivery time. Follow the issuer’s instructions. If the number changes, review subscriptions, utilities, memberships, and other legitimate recurring payments that need the new details.

How the fraud investigation works
If the issuer considers holding you responsible for an unauthorized transaction, Regulation Z requires a reasonable investigation. The rule does not prescribe one identical script for every issuer. Investigators may review transaction data, merchant information, authentication records, your account history, and your explanation of what happened.
The issuer may ask for cooperation
You may be asked to answer questions, complete a form, provide a written statement, or supply documents. A police report or affidavit is not automatically mandatory in every credit-card case. Regulation Z does not let an issuer automatically deny a claim solely because a cardholder refuses a particular request, such as an affidavit or police report. However, missing information can affect the outcome when the issuer otherwise has no facts confirming that the use was unauthorized. Respond accurately and keep copies of everything you submit.
“I do not recognize this charge” is not the same as confirmed fraud
First check whether the merchant uses a different billing name, whether another authorized user made the purchase, or whether a subscription renewed. A purchase that you authorized but found defective, late, or misrepresented is generally a merchant or billing dispute, not automatically fraud. Describe the facts precisely: say that you did not authorize the transaction when that is true, and use the issuer’s separate process for a service, merchandise, or credit-not-received problem when you did authorize it.

How much can you be required to pay?
Federal credit-card rules generally cap a cardholder’s liability for unauthorized use at $50, subject to statutory conditions. The issuer may choose to impose no liability at all; Regulation Z states: “A card issuer is not required to impose liability on a cardholder for the unauthorized use of a credit card.” See the CFPB’s Regulation Z, 12 CFR § 1026.12.
| Situation | What the federal guidance says |
|---|---|
| Unauthorized credit-card use before you notify the issuer | Liability is generally limited to a maximum of $50 when the statutory conditions are met. |
| Unauthorized use after you notify the issuer of loss, theft, or possible unauthorized use | The issuer may not impose liability for unauthorized use after notification, subject to the applicable statutory conditions. |
| Only the account number was stolen; the physical card was not lost | CFPB consumer guidance says the cardholder is not responsible for unauthorized charges. |
| Lost or stolen card reported to the issuer | The FTC says charges made after reporting the loss are not the consumer’s responsibility. |
Whether a particular transaction was unauthorized and which statutory conditions apply depend on the account facts. Do not assume that every claim will be processed identically or that an issuer’s first phone response is its final determination.
The written billing-error deadline
For a credit-card billing-error dispute under the Fair Credit Billing Act, the FTC says your written notice generally must reach the issuer within 60 days after the first statement containing the error was sent. This is a credit-card deadline; it is not the debit-card deadline for electronic transfers.
Send the notice to the correct address
- Check the statement for the issuer’s billing-dispute address and instructions.
- Identify the account, the transaction date and amount, and why you believe it is unauthorized.
- State what correction you request, such as removing the charge and related fees or interest.
- Send the notice early enough for it to arrive within the 60-day period.
- Keep a complete copy and proof of delivery or electronic submission.
A phone call is useful for immediate blocking and documenting the report, but it does not replace the written billing-error notice when the FCBA deadline applies. The FTC’s consumer guidance on credit-card disputes is available at Using Credit Cards and Disputing Charges.

There is no single universal credit-card investigation duration established by the official sources used here. The issuer reviews the claim and then communicates its decision and any account adjustment under its procedures and the applicable law. The sources also do not establish a universal temporary or provisional credit practice for credit-card fraud claims.
Do not rely on a promise that a credit-card claim will receive a provisional credit in 10 days. The commonly quoted 10-business-day investigation figure, temporary-credit rule, and certain 45- or 90-day outer periods belong to debit-card and electronic-fund-transfer guidance, not automatically to credit-card disputes. The CFPB explains those debit rules in its unauthorized electronic-transfer guidance.
Rank #4
| Feature | Credit-card fraud or billing dispute | Debit-card or electronic-fund-transfer dispute |
|---|---|---|
| Core framework | Regulation Z and the Fair Credit Billing Act apply to the relevant credit-card claim. | Electronic-fund-transfer rules apply. |
| Investigation timing | No single universal number is established for every credit-card claim. | CFPB guidance discusses investigations within 10 business days in specified circumstances. |
| Temporary credit | No universal temporary-credit practice is established by the cited sources. | Temporary credit may be required under specified conditions. |
| Longer resolution periods | Do not import debit-card outer periods into a credit-card claim. | CFPB guidance describes certain 45- or 90-day periods in specified cases. |
| Written notice deadline highlighted by the FTC | Generally 60 days after the first statement containing the billing error was sent. | The credit-card 60-day rule does not substitute for debit-transfer notice rules. |
What to do while the issuer reviews the claim
- Continue checking the account for additional unauthorized transactions.
- Keep the report confirmation, case number, call log, letters, forms, screenshots, and statements together.
- Follow instructions about changing the card number, security credentials, or access methods.
- Watch for legitimate recurring payments that may fail after a replacement card is issued.
- Read each statement for fees, interest, or re-posted transactions connected with the disputed charge.
- Answer requests for information accurately and by the stated deadline.
- Do not discard the compromised card or related records until the issuer tells you how to handle them.
If the issuer places a disputed amount back on the account or sends a decision, compare it with your records. Ask for an explanation in writing if the decision is unclear.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What if the issuer denies the claim?
Ask for the reason and preserve the paper trail
Request the issuer’s explanation, the outcome of its review, and the next step in its written dispute process. If you have new facts—such as proof that you were elsewhere, evidence that the card was in your possession, or information showing that the merchant used an unfamiliar billing name—submit them through the channel the issuer specifies.
Escalate an unresolved response
Follow the issuer’s written instructions rather than opening duplicate claims through unrelated channels. If the issue remains unresolved, the FTC identifies the FTC and CFPB as complaint channels for problems with a provider’s response. A complaint does not replace the issuer’s billing-dispute process, so retain the original notice and all supporting records.

Credit card versus debit card: why the distinction matters
Credit cards and debit cards can show similar-looking fraudulent transactions, but the legal frameworks, deadlines, and timing expectations differ. A debit transaction removes money from a bank account, while a credit-card charge appears on a credit account. That difference is why debit-card advice about provisional credit or 10-day investigations should not be used to predict a credit-card result.
Stolen card, stolen number, and a charge you authorized
Physical card stolen
Report the loss immediately through the issuer’s phone or app channel and follow up in writing. The FTC says reporting promptly protects you from responsibility for charges made after the report. Ask whether the issuer will block the card and issue a replacement, then update recurring payments after the new number arrives.
Account number exposed without losing the card
Notify the issuer as soon as you see an unauthorized charge. CFPB consumer guidance says that when only the account number is stolen, the cardholder is not responsible for unauthorized charges. The issuer may still investigate the specific transactions and may replace the account number as a security measure.

If you made the purchase but the goods were not delivered, were defective, or were not as described, explain that it is a merchant or billing problem rather than claiming an unauthorized transaction. The issuer may have a different dispute route and may ask for evidence of your attempt to resolve the issue with the merchant.
A practical reporting checklist
- Report the suspicious charge or missing card immediately.
- Ask how to submit written follow-up and confirm the correct address or upload path.
- Record the report date, confirmation number, representative, and disputed transactions.
- Send the written billing-error notice within the applicable 60-day period measured from the first statement containing the error.
- Keep copies of every letter, form, statement, screenshot, and delivery confirmation.
- Monitor the account and follow instructions about blocking or replacing the card.
- Update legitimate recurring payments if the account number changes.
- If denied, request the explanation and follow the issuer’s written reconsideration or dispute steps.
- If the response remains unresolved, consider filing a complaint with the CFPB or FTC while preserving your records.
Bottom line for a reported credit-card fraud claim
Reporting starts an issuer review; it does not guarantee an immediate refund or temporary credit. Prompt notice, a written record, and a timely billing-error letter protect your position. Federal law generally limits unauthorized-use liability to $50 and protects later unauthorized charges after notice under the applicable conditions, while the issuer must reasonably investigate before trying to impose liability. Keep credit-card rules separate from debit-card electronic-transfer timelines, and ask the issuer for the status and next required step rather than assuming a fixed number of days.
