  • 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.

  • 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.

    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.
