Under U.S. Regulation E (§ 1005.6) of the Electronic Fund Transfer Act, Wells Fargo debit cardholders face $50 max liability for unauthorized electronic fund transfers (EFTs) if notified within 2 business days of learning of card loss or theft. Liability rises to a $500 maximum if notification comes later. Banks must investigate reported unauthorized EFTs. This federal rule controls Wells Fargo debit disputes.
The Controlling Rule: Regulation E Liability Limits
Regulation E § 1005.6 sets strict liability limits for unauthorized EFTs from debit cards linked to bank accounts. The key trigger is when you "learn" of the loss or theft of your access device. If you notify Wells Fargo within 2 business days of that point, your maximum loss is the lesser of $50 or the unauthorized transfers that occur before notice.
The 2-business-day period ends at 11:59 p.m. of the second business day. Business days follow the bank's policy, which may include Saturdays. After 2 business days, liability can reach the lesser of $500 or unauthorized transfers before notice plus amounts transferred within specified periods post-notice. These limits apply to U.S. consumer accounts. Full text: CFPB Regulation E § 1005.6.
Wells Fargo, like all U.S. banks, must follow these rules and investigate reported unauthorized transactions.
What Does Not Control This Dispute
Unauthorized debit card disputes follow Regulation E for EFTs from bank accounts, not Regulation Z rules for credit card billing disputes.
This process also differs from merchant chargebacks or merchant refund policies. Wire transfers, P2P app transfers outside EFT scope, and non-EFT payments fall outside Regulation E protections.
Practical Next Steps to Report and Dispute
Notify Wells Fargo of the unauthorized transaction, card loss, or theft immediately--oral or written notice starts the process and locks in the lower liability limit. Use the Wells Fargo app, online banking dispute tools, or call customer service (check your account statements or Wells Fargo site for current numbers).
Gather evidence before contacting: bank statements showing the transaction, date you learned of the issue, screenshots of account activity, and records of your notification (e.g., call confirmation number or email timestamp). The bank must investigate.
| Action | Details | Evidence to Gather |
|---|---|---|
| Notify bank | Oral or written; aim for within 2 business days of learning of loss/theft | Timestamped call log, email receipt, chat transcript |
| Monitor response | Bank investigates unauthorized EFT | Transaction details, statement excerpts |
| Escalate if needed | File CFPB complaint if unresolved | All prior correspondence, evidence of notification timing |
If Wells Fargo does not resolve satisfactorily, submit a complaint via the CFPB portal. Track your case reference for follow-up.
FAQ
What counts as "learning" of the unauthorized transaction or card loss under Reg E?
The point you discover or should have discovered the loss/theft or unauthorized transfer, such as checking your account balance or statement.
Does Saturday count as a business day for the 2-day notification window?
It depends on Wells Fargo's policy--many banks treat Saturdays as business days; confirm via their disclosures.
Can I dispute verbally, or must it be written?
Regulation E allows oral notification to start liability limits and investigation; follow up in writing if requested.
What if the unauthorized debit was fraud via online/app access, not physical card theft?
Regulation E § 1005.6 covers unauthorized EFTs regardless of method, as long as from your account via access device.
