If you are in immediate financial danger, call your bank NOW — the number is on the back of your card. Then return to this checklist.


PHASE 1: IMMEDIATE (Within the First Hour)

Step 1: Freeze or Lock Your Card

  • Open your banking app → Card Settings → Freeze/Lock Card
  • If you cannot access the app: Call the number on the back of your card immediately
  • Ask the bank to freeze all outgoing transfers pending investigation

Step 2: Identify All Suspicious Transactions

Before calling, note for each suspicious transaction:

  • Date of the transaction
  • Amount
  • Merchant name or ATM location shown
  • Whether you still physically have your card

Step 3: Call Your Bank's Fraud Line

  • Use the number on your card or your bank's official website — not a number from a suspicious message
  • Say: "I have unauthorised transactions on my account and I want to report fraud and raise disputes"
  • Ask for: a case reference number (write it down)
  • Ask for: expected resolution timeline
  • Ask for: whether provisional credit will be applied
  • Request a replacement card with a new number

Step 4: Report to Authorities

  • UK: Action Fraud — 0300 123 2040 or actionfraud.police.uk
  • US: FTC — reportfraud.ftc.gov | (for online fraud: ic3.gov)
  • EU: Local police + national financial supervisory authority
  • Note the crime reference number provided — your bank may require it

PHASE 2: SECURE YOUR ACCOUNTS (Same Day)

Step 5: Change Credentials — From a Clean Device

  • Change your online banking password (use a device you trust)
  • Update your PIN when your replacement card arrives — do not reuse the old PIN
  • Change passwords on any other account where you used the same password
  • Check your registered email address in your banking account — has it been changed?
  • Check your registered phone number in your banking account — has it been changed?

Step 6: Review and Strengthen Your 2FA

Step 7: Check All Linked Accounts

  • Review all accounts linked to the compromised card or account
  • Check any accounts that use the same email address and password
  • Check digital wallets (Apple Pay, Google Pay) — are there unfamiliar cards added?
  • Review any financial apps connected to your account (budgeting apps, payment services)

PHASE 3: WIDER IMPACT ASSESSMENT (Within 72 Hours)

Step 8: Check Your Credit Report

  • Request your credit report from all major bureaus
  • Look for: accounts you did not open, credit queries you did not authorise, unfamiliar addresses
  • If fraudulent accounts have been opened: contact each lender directly and report fraud

Step 9: Consider a Fraud Alert or Credit Freeze

Step 10: Protect Your Phone Number (If Relevant)


PHASE 4: DOCUMENT AND MONITOR (Ongoing)

Step 11: Maintain a Fraud Log

Keep a written log with:

  • Date and time of each fraud event
  • Date and time of each action you took
  • Names of bank staff spoken to
  • All case and reference numbers
  • Outcome of each step

Step 12: Monitor Your Account

  • Enable real-time transaction alerts if not already active
  • Check your account statements daily for at least 60 days
  • Follow up with your bank if disputes are not resolved within the stated timeframe

Step 13: Escalate If Needed

If your bank disputes your claim or does not resolve within the timeframe:

  • Ask for a written explanation of their decision
  • Ask to escalate within the bank (senior complaints team)
  • Contact the financial ombudsman:
  • UK: financial-ombudsman.org.uk
  • EU: Your national ADR/ombudsman scheme
  • US: Consumer Financial Protection Bureau — consumerfinance.gov
