U.S. Regulation E limits your liability for unauthorized debit card transactions at Fifth Third Bank to the lesser of $50 or the amount of unauthorized transfers before notice if you notify the bank within two business days after learning of the loss or theft of your access device. Liability rises to the lesser of $500 or a specified sum if notification comes later. This federal rule under the Electronic Fund Transfer Act (EFTA) controls, not credit card dispute rules. Contact Fifth Third Bank's Disputes Resolution Department by phone, following prompts for check product disputes, or visit a local banking center immediately to report and minimize exposure.

Regulation E Controls Unauthorized Debit Card Liability

Regulation E (§ 1005.6), enforced by the Consumer Financial Protection Bureau (CFPB), sets consumer liability limits for unauthorized electronic fund transfers (EFTs) using debit cards linked to bank accounts. If you notify your bank within two business days after learning of the loss or theft of your access device--such as a debit card or PIN--your liability shall not exceed the lesser of $50 or the amount of unauthorized transfers that occur before notice.

Notification after those two business days increases potential liability to the lesser of $500 or the sum of $50 plus unauthorized transfers before notice and before the end of the 60-day period (though primary evidence focuses on the initial two-day window). Business days exclude Sundays and federal holidays; for example, if you learn of the issue on a Saturday (a business day), the two-business-day period ends at 11:59 p.m. the following Friday if timely notified.

Notification Timing Maximum Liability
Within 2 business days of learning of loss/theft Lesser of $50 or unauthorized amount before notice
After 2 business days Lesser of $500 or specified sum (e.g., $50 + amounts before 60-day period end)

What Does Not Control This Dispute

Unauthorized debit card disputes follow EFTA/Regulation E, distinct from credit card billing disputes under the Fair Credit Billing Act (FCBA), which caps liability at $50 regardless of timing. Merchant refund policies or chargebacks do not apply here, as this involves bank account EFTs, not credit card purchases. Wire transfers and non-EFT payments fall outside Regulation E protections.

Fifth Third Bank's process aligns with these federal requirements but reflects bank policy, not additional legal rights.

How to Report to Fifth Third Bank

Next Steps and Escalation
