The short answer
For a U.S. credit-card billing error, the issuer must receive your written notice within 60 days after the first statement showing the error was sent to you. The issuer generally must acknowledge the complaint within 30 days, unless it has already resolved the issue, and resolve the dispute within 90 days.
That is the federal billing-error procedure. It isn't a universal chargeback deadline for every card network, payment method, or type of complaint. A 120-day window is often mentioned for network disputes, but the actual date can depend on the dispute reason, the transaction, delivery or refund dates, and the issuer's instructions.
If the charge is unauthorized, call the issuer immediately. Don't wait to decide whether a 60-day or 120-day window applies.
Start with the payment method
There can be more than one clock. The payment rail and the type of complaint determine which one matters.
| Situation | Deadline or timing | What it controls |
|---|---|---|
| Federal credit-card billing error | Written notice received within 60 days after the first statement with the error was sent | Preserves the federal billing-error process |
| Issuer acknowledgment | Within 30 days, unless the issue has already been resolved | Confirms receipt of the complaint |
| Issuer resolution | Within 90 days after receiving the complaint | Applies to the federal billing-error investigation |
| Card-network dispute | Varies by network, dispute reason, and triggering event | Controls the network chargeback process |
| PayPal dispute | The date shown in the PayPal case or account process | Controls PayPal's internal process |
| Merchant representment | The date in the acquirer, processor, or issuer notice | Controls the response to an existing dispute, not the original filing |
The Federal Trade Commission's credit-card guidance describes the federal written-notice process. The Federal Reserve's Regulation Z billing-error rule contains the related regulatory requirements.
What the federal 60-day rule covers
The federal rule applies to the billing-error process for a credit-card account. Examples listed in Regulation Z include:
- An unauthorized charge
- A charge that isn't identified properly on the statement
- A payment or credit that the issuer failed to post correctly
- A computational or similar accounting error
A wrong amount, duplicate charge, or similar problem may fit an accounting-error category, depending on the facts. Other complaints, such as goods that never arrive, a recurring charge after cancellation, a refund that wasn't posted, or merchandise that doesn't match its description, may also be handled through the issuer's card-dispute process. They aren't automatically the same federal billing-error claim. Describe what happened rather than choosing a label based only on an internet checklist.
The 60-day period is measured from when the first statement containing the error was sent, not necessarily from when you noticed the problem. If you moved, the FTC says you generally need to have given the issuer your new address in writing at least 20 days before the billing period ended for these protections to apply.
A call to the merchant can help obtain a refund, but it doesn't replace written notice to the issuer. If the deadline is approaching, send the notice first.
What to put in the notice
Include:
- Your name and the account information the issuer requests
- The merchant, transaction date, and disputed amount
- A short explanation of why the charge is incorrect
- The correction or investigation you want
- Copies of relevant records, rather than your originals
Use the issuer's designated billing-dispute or billing-inquiries address or submission method. The notice must reach the issuer within the deadline; sending it to the ordinary payment address or relying only on a phone call can create a problem. Keep the letter, attachments, confirmation number, and proof of delivery.
Continue paying amounts you don't dispute. Follow the issuer's directions about the disputed balance so an unrelated missed payment doesn't create another issue.
Why 120 days isn't a universal chargeback rule
The 120-day figure usually refers to a card-network process, not one federal rule. The network clock may begin with:
- The transaction or settlement date
- The date goods or services were expected to arrive
- The date a refund or cancellation should have been processed
- The date a problem could reasonably be identified
- Another event specified for that dispute category
Different categories can use different or longer periods. An issuer may also give you an earlier operational deadline in an app, letter, or phone instruction. Use the case-specific date rather than relying on a generic 120-day summary.
Ask the issuer:
What is the last day to open this dispute, and is the deadline measured from the transaction, statement, expected delivery, refund date, or another event?
Write down the answer and the case number.
Visa, Mastercard, American Express, and Discover
Consumers generally start a network dispute with the card issuer, not with Visa, Mastercard, American Express, or Discover. The issuer takes the report, determines which process applies, and handles communication with the network.
A 120-day window is commonly associated with many Visa and Mastercard dispute explanations, but the reason code and triggering date can change the result. American Express has its own dispute workflow, and Discover's applicable category and issuer procedure control the filing date. Don't transfer a deadline from one network to another.
Even when a 120-day window appears relevant, filing on day 120 isn't a guarantee of acceptance. The claim can still fail because the wrong event date was used, the facts don't match the dispute category, or the issuer required an earlier submission.
PayPal, Stripe, and Square
The name shown on a transaction doesn't always identify the party that controls the dispute.
PayPal
PayPal may offer an internal dispute process separate from a chargeback through the card issuer. If you use that route, follow the deadline displayed in the PayPal case or Resolution Center.
When a PayPal payment was funded by a credit card, the issuer may have a separate billing-error or network process. Ask the issuer how it handles that transaction, and tell both providers if you have already opened a case. Don't seek duplicate recovery for the same loss.
If the payment came from a PayPal balance, bank account, or another non-card source, the federal credit-card billing-error rule doesn't automatically apply.
Stripe and Square
Stripe and Square generally process payments for merchants. They aren't substitutes for the credit-card issuer shown on your statement. If a merchant used either processor and the charge appears on your card statement, contact the issuer.
A processor's deadline for a merchant to submit evidence or answer a chargeback is a merchant-side deadline. It doesn't calculate the consumer's federal 60-day period or necessarily tell you when to start a dispute.
Record the dates that may matter
Make a short timeline:
- Transaction date and amount
- Date the first statement showing the charge was sent
- Promised or expected delivery date, if relevant
- Date you canceled, returned the item, or requested a refund
- Date the merchant acknowledged the issue
- Date you noticed or reported an unauthorized transaction
- Deadline shown by the issuer, PayPal, or another platform
If two dates might apply, contact the issuer using the earlier one as your working deadline. Ask which event controls and request the answer in writing.
How to file before the deadline
1. Confirm the payment rail
Check whether the transaction used a credit card, debit card, prepaid card, ACH, bank transfer, PayPal balance, or another method. The federal 60-day credit-card procedure doesn't automatically govern debit-card, ACH, wire-transfer, or peer-to-peer payment disputes.
2. Report unauthorized transactions now
Call the number on the back of the card or use the issuer's official app. Ask whether the card should be locked or replaced and what written follow-up is required. Save the fraud-report reference number.
3. Contact the merchant if time allows
A merchant refund may be faster than a formal dispute. Ask for written confirmation of any promised refund, but don't let the merchant's investigation run past the issuer's deadline.
4. Send written notice to the issuer
State that you're disputing a charge or billing error. Include the transaction details, amount, reason, and copies of supporting records. Follow the issuer's instructions for the correct submission channel.
A factual format is enough:
I am writing to dispute a charge on my account ending in [last four digits]. The merchant is [name], the transaction date is [date], and the amount is [amount]. I believe the charge is incorrect because [brief explanation]. Please investigate and correct the account. Copies of the relevant records are enclosed.
5. Preserve delivery proof
Save the notice, attachments, screenshots, confirmation number, and delivery record. A representative's statement that a case was opened isn't a substitute for your own record of when the issuer received the written dispute.
6. Watch for follow-up
Record when the issuer acknowledges the complaint, requests more information, applies a temporary adjustment, or sends a final decision. If the result is unclear, ask for the decision and explanation in writing.
Send evidence that matches the problem
Specific, chronological records are more useful than a large unorganized file.
| Dispute type | Useful records |
|---|---|
| Unauthorized charge | Statement, transaction alerts, relevant information about access to the card, and communications reporting the fraud |
| Wrong amount or duplicate charge | Receipt, invoice, order confirmation, and a comparison showing the difference |
| Item or service not received | Order confirmation, promised delivery date, tracking information, and messages to the merchant |
| Refund not posted | Refund confirmation, return receipt, cancellation notice, and the later statement |
| Recurring charge after cancellation | Cancellation request, cancellation terms, confirmation, and the subsequent charge |
| Merchandise problem | Product description, photos, return records, and the merchant's response |
Put the disputed amount and the key date on the first page. Send copies and keep your originals.
If you missed the deadline
Submit the dispute immediately anyway. Explain why it is late and include records showing when you discovered the issue, when delivery was expected, or when the merchant promised a refund.
A late request might still be considered under a network exception, a platform's internal rules, or the issuer's own review process. That is fact-specific and discretionary. It isn't a guaranteed extension of the federal 60-day procedure.
If the issuer denies a dispute, ask for:
- The specific reason for the denial
- The documents or information used in the decision
- Whether the claim was treated as a federal billing error or a network dispute
- The deadline and method for requesting another review
- A written explanation of any remaining balance
If you believe the issuer failed to follow the billing-error process, use its formal complaint or escalation channel. Compare the response with the FTC guidance and Regulation Z information linked above, and keep every response and case number.
A merchant's rebuttal is a separate clock
A merchant that receives a chargeback notice may have a limited period set by its acquirer or processor to accept the charge or submit evidence. That period begins after the dispute is opened. It doesn't tell a consumer when the original dispute should have been filed, and it doesn't extend the federal 60-day period.
If the issuer sends you the merchant's response or asks you to answer it, follow the date and submission method in that notice. PayPal's seller guidance on chargeback evidence says evidence should be submitted together because there may not be another opportunity to add more. That is a response-stage instruction, not a consumer filing deadline.
Common deadline mistakes
- Treating 120 days as a universal legal deadline
- Applying the credit-card rule to a debit card, ACH transfer, or PayPal-balance payment
- Calling the issuer but never sending the required written notice
- Waiting for the merchant's refund decision before notifying the issuer
- Counting from the purchase date when the relevant event is the statement, delivery, cancellation, or refund date
- Sending the notice to the payment address instead of the issuer's billing-dispute channel
- Ignoring the case-specific date in an issuer or PayPal notice
- Filing duplicate claims without telling the providers about the other case
Frequently asked questions
Is 120 days the chargeback deadline?
Not universally. It's a common network benchmark for many card disputes, but the network, dispute reason, triggering event, issuer, and platform can change the deadline.
Is the U.S. credit-card deadline 60 or 120 days?
They control different processes. The federal billing-error procedure generally requires written notice within 60 days after the first statement with the error was sent. A network chargeback may use another window, often described as 120 days for many categories.
Do I have to contact the merchant first?
No. You can request a merchant refund, but don't wait for a response if the issuer's deadline is close. Send timely written notice to the issuer.
Can I use the same 60-day rule for a debit-card charge?
Not automatically. Debit cards, ACH, prepaid cards, and other payment methods follow different rules and procedures. Contact the relevant financial institution promptly.
How long does the issuer have to decide?
For a federal credit-card billing-error complaint, the issuer generally must acknowledge it within 30 days unless it has already been resolved and resolve it within 90 days. A network or platform case can follow a different schedule.
What if I missed 60 days?
Report the problem immediately, explain the delay, and ask whether a network or internal exception applies. The issuer may still review the claim, but a late request isn't guaranteed to receive the federal billing-error process.
If the deadline is close, send the issuer's written notice today through its designated billing-dispute channel and save proof that it arrived.
