  • Limit

    If the consumer does not report within two business days after learning of the loss or theft, liability is "the lesser of $500 or the sum of" up to $50 of transfers in the first two business days and later transfers the institution shows would have been prevented by timely notice.

    Source: consumerfinance.gov, verified 2026-10-12

  • Deadline

    An unauthorized transfer that appears on a periodic statement must be reported "within 60 days of the financial institution's transmittal of the statement" to avoid liability for later transfers that timely notice would have prevented. The institution must extend these time limits to a reasonable period when extenuating circumstances (for example extended travel or hospitalization) delayed notice.

    Source: consumerfinance.gov, verified 2026-10-12

  • Process

    Notice of an unauthorized transfer may be given in person, by phone or in writing. Written notice is considered given at the time the consumer mails it. Lower liability under state law or the account agreement controls.

  • Policy

    An unauthorized EFT is a transfer from the consumer's account initiated by someone other than the consumer without actual authority and from which the consumer receives no benefit. It does not include a transfer by a person to whom the consumer gave the access device (until the consumer tells the institution that person is no longer authorized), a transfer made with fraudulent intent by the consumer or someone acting with the consumer, or a transfer by the institution or its employee.

  • Policy

    Errors covered by the error-resolution procedure include an unauthorized EFT, an incorrect EFT to or from the account, an omitted transfer on a statement, a computational or bookkeeping error, receiving the wrong amount of cash from an ATM, and a request for documentation or clarification about a transfer.

    Source: consumerfinance.gov, verified 2026-10-12

  • Deadline

    The consumer must give notice of an error no later than 60 days after the institution sent the periodic statement on which the error first appears. The notice must let the institution identify the consumer's name and account and say why the consumer believes there is an error. If notice is oral, the institution may require written confirmation within 10 business days.

    Source: consumerfinance.gov, verified 2026-10-12

  • Deadline

    The institution must investigate and decide within 10 business days, report results within 3 business days after it completes the investigation, and correct an error within 1 business day after it finds one. It may take up to 45 days only if it provisionally credits the disputed amount within 10 business days. It need not provisionally credit if it asked for written confirmation of an oral notice and did not receive it within 10 business days.

  • Deadline

    Longer periods apply in some cases: 20 business days instead of 10 for transfers within 30 days after the first deposit to a new account, and 90 days instead of 45 for point-of-sale debit card transactions, transfers not initiated within a state, and new-account transfers.

    Source: consumerfinance.gov, verified 2026-10-12

  • Process

    If the institution finds no error, it must give a written explanation and tell the consumer of the right to request the documents it relied on. If it debits a provisional credit, it must notify the consumer of the date and amount and honor checks and preauthorized transfers for five business days after the notice.

  • Policy

    P2P (CFPB guidance, not rule text): the CFPB's Electronic Fund Transfers FAQs state that any P2P payment that meets the definition of an EFT is covered by EFTA and Regulation E, and that when a consumer is fraudulently induced into sharing account access information with a third party, the resulting transfer by that third party is an unauthorized EFT.

  • Process

    CFPB guidance (Electronic Fund Transfers FAQs): an institution must begin its investigation promptly on an oral or written notice of error and may not require a police report or require the consumer to contact the merchant first. Consumer negligence, such as writing a PIN on the card, cannot be used to impose greater liability.

• Fair Credit Billing Act billing-error and purchase-dispute rights (Regulation Z)
  12 CFR 1026.13; 12 CFR 1026.12(c) (Regulation Z)

  For credit card and other open-end credit accounts, a written billing-error notice that the creditor receives within 60 days after it sent the first statement with the error starts a dispute process. The creditor must acknowledge it within 30 days and resolve it within 2 complete billing cycles (no later than 90 days). Until then, the consumer need not pay the disputed amount and the creditor may not collect it or report it as delinquent. A separate rule lets a cardholder assert claims and defenses about a card purchase against the card issuer.
