You open a statement and see a charge you do not recognize. Before you panic, work out two things: which account it hit, and what kind of problem it is. A credit card billing error and an unauthorized debit from a bank account follow different federal rules, with different deadlines.

A folded paper statement, a pen and a wall calendar with a few dates circled on a kitchen table in soft morning light, suggesting the careful steps of checking a charge.
Checking a statement date and noting the response window before contacting the card issuer or bank.

Check the boring explanations first

Many unfamiliar charges turn out to be ordinary. A merchant may bill under a parent company or a payment processor, so the name on your statement may not match the store sign. A hotel or gas pump may place a pending authorization that later drops off or changes amount. A family member may have used a card you share. A free trial may have converted to a paid plan.

  1. Look at the date and amount. Match them against receipts, emails and subscriptions.
  2. Search your email for the amount or the name on the statement.
  3. Ask anyone else who has access to the card or account.
  4. If a pending charge looks odd, check again in a day or two.

If none of that explains it, treat the charge as a problem and contact your card issuer or bank right away. Use the phone number on the back of your card or on the official website, not a number from a text or email. Ask whether the card should be closed and replaced. A replacement card stops further charges on the old number, though it does not by itself settle the disputed one.

Fraud and billing errors are not the same thing

An unauthorized charge means you did not make it and did not permit anyone else to. A billing error can be a wrong amount, a charge for something you never received, or a math mistake. The CFPB notes that a dispute over defective goods or services may follow a different process than a billing error. Say plainly which one you think it is when you call, and ask the representative to note it on the account.

The word "chargeback" is often used for all of this. In everyday use it means the money is pulled back from the merchant after you dispute a charge. The federal rules discussed here are what protect you as a consumer. How a card network handles a dispute behind the scenes is a separate matter, and the rules and timing can vary, so ask your issuer what to expect.

Credit cards: the 60-day written notice

For a credit card, billing-error rights come from Regulation Z, in Section 1026.13. The CFPB says that to protect your rights, you must send the card company a written billing error notice within 60 calendar days after the charge first appeared on your statement. Call right away, too. But the written notice is what the deadline is tied to.

After the company receives your notice, it has 30 days to send a letter confirming it got the dispute. The exception is when it has already finished the required billing error procedures within that time. Keep a copy of what you send, and note the date.

If you already paid the charge, you can still dispute it. You probably will not get the money back until the card company decides you were right. If it finds the bill was wrong, it must remove the charge. If it decides the bill was correct, it must explain why in writing, state how much you owe, and give the payment due date. The CFPB's credit card dispute guidance also advises checking your card agreement for your rights on unauthorized charges.

Bank accounts and debit cards: speed matters

Debit card and other electronic transfers fall under Regulation E. Two sections matter most. Section 1005.6 covers a consumer's liability for unauthorized transfers. Section 1005.11 covers how an institution must resolve errors. Under the liability rule, how much you could be responsible for can depend on how quickly you report, so do not wait. Read the exact tiers and conditions in Section 1005.6 before you rely on any figure you hear on a call.

On timing, a CFPB regulations search result indicates that an institution generally must investigate an electronic transfer error within 10 business days, and may take up to 45 days from receiving notice if it needs more time. Confirm the conditions in Section 1005.11, including any rules on temporary credit while the investigation continues. Your account agreement may add details.

Debit disputes are riskier in one practical way: the money has already left your account. Report quickly, ask the bank to confirm the date it received your notice, and ask what it will tell you in writing.

Keep a short paper trail

Put everything in one file. Write down the date the charge appeared, when you called, who you spoke with, and when you sent any written notice. Keep the responses. Those dates tell you whether you are inside the 60-day credit card window or the investigation periods for a bank account.

When you call, a few direct questions help. Did you receive my written notice, and on what date? Will you send a confirmation letter? If you decide the charge is valid, will you explain why in writing, with the amount owed and the due date? For a debit transaction, which Regulation E steps apply, and what happens to the money while you investigate?
