Regulation E
Regulation E is the federal regulation implementing the Electronic Fund Transfer Act, providing consumer protections for electronic payments including debit card transactions, ACH transfers, and peer-to-peer payments.
Regulation E establishes: consumer rights to error resolution (a 60-day window to dispute unauthorized transactions), provisional credit during investigation (10 business days), liability limits for unauthorized transactions (limited liability if reported within 2 business days; up to $500 if reported within 60 days), and required disclosures about electronic fund transfer terms.
For embedded finance programs that handle consumer funds — debit card programs, consumer P2P, earned wage access, digital wallets — Regulation E compliance is non-negotiable. The dispute resolution and error correction processes must be designed and staffed before launch.
Regulation E vs. card network chargeback rules: for consumer debit transactions, Regulation E provides the legal framework while card network chargeback rules define the operational process. Both apply simultaneously. Commercial card transactions are generally not covered by Regulation E.
