Regulation E (Reg E)

What is Regulation E?

Regulation E is the Consumer Financial Protection Bureau rule, 12 CFR Part 1005, that implements the Electronic Fund Transfer Act. It sets the rights and responsibilities of consumers and financial institutions for electronic fund transfers, including debit card, ATM, ACH and certain prepaid account transactions, covering disclosures, consumer liability for unauthorized transfers and the procedures for resolving errors.

What does Regulation E cover?

The rule applies to electronic fund transfers involving consumer accounts. It requires initial disclosures when a consumer contracts for an electronic fund transfer service (1005.7), receipts and periodic statements (1005.9), limits on consumer liability for unauthorized transfers (1005.6), and a defined process for investigating errors (1005.11). Record retention rules sit in 1005.13.

How does Reg E error resolution work?

A consumer has 60 days from the statement on which an error first appears to notify the bank. The bank must determine whether an error occurred within 10 business days. If it needs more time, it can take up to 45 days if it provisionally credits the consumer's account within the first 10 business days. The 45 days extends to 90 for point-of-sale debit, transfers not initiated within a state, and transfers within 30 days of the account's first deposit, where the initial period is also 20 business days.

The bank reports results to the consumer within three business days of finishing the investigation and corrects any error within one business day of determining it occurred. A no-error finding must come with a written explanation and notice that the consumer can request the documents relied on.

How does Reg E relate to AI employees?

Error resolution is deadline-driven casework: intake, evidence gathering, timeline tracking and notice drafting. An AI employee can run those steps with an audit trail, while a trained analyst makes the final determination and approves exceptions. Our guide to Reg E dispute investigation automation covers the split in detail.

Frequently asked questions

Is Regulation E the same as the Electronic Fund Transfer Act?

No. The Electronic Fund Transfer Act is the federal statute. Regulation E is the CFPB rule in 12 CFR Part 1005 that implements it and sets the detailed requirements financial institutions follow.

Does Regulation E apply to credit card disputes?

No. Regulation E covers electronic fund transfers to or from consumer asset accounts, such as debit card and ACH transactions. Credit card billing errors fall under Regulation Z (12 CFR 1026.13), which has its own written-notice and resolution timelines.

How many days does a consumer have to report an error under Reg E?

A notice of error must reach the bank within 60 days after the bank sends the periodic statement on which the error first appears. The notice can be oral or written.

Does Regulation E apply to business accounts?

Regulation E protects consumers, meaning natural persons (12 CFR 1005.2(e)), and its accounts are those established primarily for personal, family or household purposes (1005.2(b)). Business accounts are generally outside it, though account agreements and network rules may offer similar rights.
