Understanding Debit Card Disputes: Unauthorized Charges vs Billing Errors

Unauthorized charges (fraud like CNP or counterfeit, per 2026 Federal Register) differ from billing errors (wrong amount, non-delivery). Fraud: Someone stole your details--zero liability if reported promptly. Errors: Merchant mistakes.

Federal Rights Under Reg E (2026 Updates): Regulation E (EFTA) mandates banks investigate within 10 business days, providing provisional credit for verified fraud. Report within 60 days of statement. Contrast with Reg Z (credit): 60-day notice, 90-day resolution. Visa offers 120 days but FTC sticks to 60 for debit.
