Notify the institution the right way

Tell your bank or credit union the transaction was unauthorized. Provide date, amount, and enough account detail to identify the transfer. Use phone and then written/portal confirmation. Notice timing can affect both liability under §1005.6 and error-resolution rights under §1005.11.

CFPB summaries commonly state you generally should report within 60 days after the statement showing the transfer is sent. Do not aim for day 59—report as soon as you discover the problem.

Investigation clocks beginners hear about

CFPB Ask CFPB money-back guidance explains that once notified, the institution generally has ten business days to investigate (20 if the account is very new). It must correct an error within one business day after determining an error occurred, then generally has three business days to report findings. You can request the information used to decide.

If the institution needs more time, it generally must provide provisional (temporary) credit for the disputed amount minus up to $50 while investigating. Outer resolution windows are often summarized as 45 days, or up to 90 days for certain foreign, new-account, or point-of-sale debit situations.

If the institution concludes the transfers were authorized, it must provide written notice before removing provisional credit.

Investigation timeline basics

What to include in a written dispute

  • Your name and account identifiers
  • Why you believe the transfer is an error/unauthorized
  • Dollar amount and date
  • Date you discovered it
  • Date/time of any prior phone notice
  • Supporting facts (card never lost, travel alibi, etc.)

Living on provisional credit

Provisional credit is temporary. Avoid spending every dollar of a provisional credit as if the investigation were finished. Keep records in case the institution reverses the credit after finding the transfer authorized.

Special fact patterns

CFPB Ask CFPB states that if you gave a friend your debit card and they took more than agreed, the bank generally does not have to refund those transfers because you authorized the friend—until you notify that the friend is no longer authorized.

If a telemarketer debited your checking account without agreement, CFPB says contact the institution immediately, say you never authorized the payment, and ask for a reverse. ACH-processed checks can have additional protections; FTC Telemarketing Sales Rule authorization rules may also matter.

Parallel FTC steps

Follow FTC lost-or-stolen guidance for written follow-up. If identity theft is broader than one debit, use IdentityTheft.gov. Report scam patterns at ReportFraud.ftc.gov.

Everyday example: three small unauthorized groceries

You spot three $40–$60 grocery debits you did not make. Report all related transfers as a series, request card reissue, ask about provisional credit, and review whether a skimmer could have captured your card at a prior stop.

Myths

  • Myth: “I must dispute with the store before the bank.” For unauthorized EFTs, notify the institution promptly.
  • Myth: “Provisional credit is final.” It can be reversed with notice if the bank finds no error.
  • Myth: “Email to a random teller counts.” Use the official error-notice channel in your disclosure.

Dispute checklist

  1. Notify via official phone/app immediately
  2. Send written/portal error notice with facts
  3. Ask about provisional credit and deadlines
  4. Replace card; update recurring payments
  5. Save all bank letters and dates
  6. Request investigation documents if denied
  7. Escalate via CFPB complaint only after you understand the bank’s written reason
  8. Add IdentityTheft.gov if identity misuse appears

If your dispute is denied

Ask for the written explanation and the documents the bank relied on. Compare the reason to Regulation E definitions of unauthorized EFT. If you furnished the card to someone, denial may align with CFPB Ask CFPB friend-card guidance. If facts support unauthorized use and timing was prompt, you may evaluate CFPB complaint options after you have the bank’s written position.

Stay organized: denials that cite late notice should be checked against your discovery date and statement date evidence.

Staying disciplined with primary sources

For electronic fund transfers, prefer CFPB Regulation E pages (§§1005.6 and 1005.11), CFPB Ask CFPB unauthorized-transaction guidance, CFPB EFT FAQs, and FTC Lost or Stolen Credit, ATM, and Debit Cards. Bank blog posts can help with app screenshots but should not override federal timing rules in your disclosure.

When a call-center script conflicts with your written Reg E disclosure, ask for the error-resolution address in writing and follow the disclosure. Save names, times, and reference numbers.

Re-read disclosures after product changes—new debit cards, digital wallets, or joint owners can change how you report and who can authorize transfers.

Alerts and monitoring that buy you time

Instant transaction alerts shrink the gap between fraud and discovery—the exact gap Regulation E liability tiers care about. Set low thresholds for ATM withdrawals and foreign POS. Review alerts the same day; do not silence them because they feel noisy.

Weekly, skim pending and posted debit transactions. Monthly, reconcile against receipts for recurring merchants. If a merchant name looks slightly off (one-letter typos), investigate before the 60-day statement window becomes relevant.

A single unauthorized debit can be isolated card fraud—or the first breadcrumb of broader identity theft. If you also see new credit inquiries, utility accounts, or IRS letters, add IdentityTheft.gov and credit freezes to the same week’s work plan.

Practice drill

Download or request your Reg E error-resolution disclosure. Draft a one-page unauthorized-EFT notice template with blanks for date, amount, merchant, and discovery date. Store it with your banking records.

If you have an old denied dispute letter, compare its reasons to CFPB unauthorized definitions—learning from past paperwork sharpens future notices.

Merchant conversations vs bank disputes

You can ask a merchant what a charge is for, but do not delay bank notice while waiting on a store manager. Unauthorized EFT clocks care about notice to the financial institution. Parallel conversations are fine; sequential delay is not.

Stronger written notice habits

Lead with “I am notifying you of an error / unauthorized electronic fund transfer under my account’s Regulation E procedures.” List each transaction date, amount, and merchant name exactly as shown. State that you did not authorize the transfers and received no benefit from them. Include the date/time of your prior phone notice.

Avoid speculation about named suspects unless you have facts. Avoid admitting you “might have” authorized something if you did not. Keep tone factual. Send to the error-resolution address in your disclosure and keep proof of delivery or portal confirmation.

If multiple small charges look related, list them as a series so investigators see the pattern. Ask the institution to confirm receipt and to state whether provisional credit will be applied.

After provisional credit posts

Update your budget so you do not depend on temporary funds. If the bank later reverses provisional credit, you want cash-flow room. Keep shopping receipts for the week of the dispute in case you need to prove where you actually were.

Bottom Line

Dispute unauthorized debit charges with prompt official notice, a clear written error description, awareness of investigation and provisional-credit clocks, and careful records—anchored to CFPB Regulation E and Ask CFPB guidance.
