What to Do If You Gave Your Bank Account or Card Number to a Scammer

If a scammer has your bank account number, debit card, or credit card information, the next 60 minutes are critical. Banks and card issuers can usually stop pending transactions if you call before the charge clears — sometimes also reverse transactions that already posted. This guide walks seniors and adult children through the exact steps in the order that matters.

Call your bank’s fraud line right now. The number is on the back of your debit or credit card — not the main customer-service number. Say: “I gave my account information to a scammer. Please freeze the account, reverse any pending transactions, and open a fraud claim.” If you’d rather talk to a person first, the National Elder Fraud Hotline at 1-833-FRAUD-11 will walk you through it.

Step 1 — Call the fraud line on the back of the card

Each bank and card issuer has a 24/7 fraud line printed on the back of the card. Have ready: your account number, the approximate dollar amount, the date and time of the call from the scammer, and what information you shared. Ask the agent for three things:

  • Stop pending transactions — anything not yet posted can usually be canceled.
  • Reverse posted transactions — under Reg E (debit) or Reg Z (credit) within 60 days you are entitled to dispute.
  • Issue a new card and account number — your old one is now permanently compromised.

Step 2 — Set a fraud alert on your credit

A free 90-day fraud alert with one credit bureau spreads to the other two. Use: Equifax 1-888-766-0008, Experian 1-888-397-3742, or TransUnion 1-800-680-7289. If the scammer also took your Social Security number, place a free credit freeze instead (more protective).

Step 3 — Watch the account daily for 30 days

Even after a new card is issued, scammers often try small “test” charges of $1–$5 to see if the old number is still live. Log into your bank’s website or app daily for 30 days and look for any unfamiliar charge — large or small. Report each one to the fraud line; do not wait.

Step 4 — File a complaint with FTC and FBI

  • FTC ReportFraud — also generates an FTC Identity Theft Report you can give your bank
  • FBI IC3 at ic3.gov — for online-based fraud
  • Your state Attorney General consumer-protection office
  • CFPB at consumerfinance.gov/complaint if your bank refuses to refund a Reg E dispute

Step 5 — If you sent a Zelle, Venmo, or Cash App payment

P2P payment apps are different from bank accounts and have their own rules. Most P2P apps treat authorized payments as final — even when authorization was the result of fraud. Call the app’s fraud team right away (in-app) and file with the CFPB and your bank. Some banks (under public pressure) now refund Zelle scam losses; others do not. Document every step in writing.

Your rights — Regulation E (debit) and Regulation Z (credit)

  • Debit cards — if reported within 2 business days, your liability is capped at $50. After 2 days but within 60 days, $500. After 60 days, no protection.
  • Credit cards — under federal law, your liability is capped at $50 for any unauthorized use, regardless of how long it takes to report.
  • ACH and wire transfers — different rules; see our wire transfer recovery guide.

How to prevent this happening again

  • Never give your full account or card number to anyone who called you.
  • Real bank fraud departments will never ask you to confirm your card number — they already have it.
  • Set up account alerts at your bank — text me when any charge over $1 is made. Free at most banks.
  • Use a credit card (not debit) for online purchases — credit cards have much stronger consumer protections.

When to call for help

National Elder Fraud Hotline: 1-833-FRAUD-11 (1-833-372-8311). Free, confidential, DOJ-staffed. Open Monday–Friday, 10 a.m.–6 p.m. Eastern Time. English, Spanish, and other languages available. They will help you identify what type of fraud occurred, document the incident, and connect you to the right reporting agencies.

Two rules that prevent most scams

Rule 1. If they called you, emailed you, or messaged you — hang up. Call back at a number you find yourself.

Rule 2. Never pay anyone in gift cards, wire transfers, cryptocurrency, or by mail. Real bills are not paid these ways.
