Quick answer

The strongest credit card fraud safeguard is to stop exposing the real card number. Use virtual card numbers for online checkout, turn on real-time transaction alerts, freeze the card when you are not using it, and check your statement every week. If a charge looks wrong, call the issuer right away and dispute it.

Prerequisites

  • Access to your card issuer's mobile app or online account
  • The customer service phone number printed on the back of your card
  • A password manager for unique account passwords
  • Your last two billing statements for comparison

How to safeguard your credit card

  1. Open your card issuer's app and turn on real-time alerts for every purchase, cash advance, and card-not-present transaction.
  2. Enable virtual card numbers if your issuer offers them, and use a new virtual number for each online merchant.
  3. Set a daily or monthly spending limit on the card if the issuer allows it.
  4. Use the freeze card control in the issuer app when the card is idle, then unfreeze it before a planned purchase.
  5. Remove the CVV and full card number from texts, emails, photos, and notes apps.
  6. Pay with tokenized checkout methods such as a mobile wallet when the merchant supports them.
  7. Review posted and pending transactions every week, not once a month.
  8. Log in to each shopping account with a unique password stored in a password manager, and turn on two-factor authentication.
  9. Shred or securely delete paper statements and receipts that show the full card number.
  10. Call the issuer right away if a card is lost, a charge is unfamiliar, or a one-time code arrives without your request.

After a suspected fraud charge

  1. Lock or freeze the card in the issuer app.
  2. Call the issuer's fraud line and state which charges you do not recognize.
  3. Send a written dispute if the issuer requires one, and keep a copy.
  4. Change passwords for the merchant account and your email account.
  5. File a report with the Federal Trade Commission and the FBI Internet Crime Complaint Center if the loss is significant.
  6. Place a fraud alert or credit freeze if your Social Security number or other identity data was exposed.

Everyday habits that reduce exposure

  • Keep the physical card in a RFID-blocking sleeve only if you also control where you set it down; a sleeve does not replace transaction alerts.
  • Use one card for online subscriptions and a separate card for in-person purchases.
  • Decline to save card details on merchant sites unless the site uses a recognized payment token.
  • Check the card reader and gas pump seal before inserting a card.
  • Never read a one-time code to anyone who calls, texts, or emails you.

What not to do

  • Do not buy card numbers, CVVs, or full card data from any person or site. Buying stolen card data is illegal and exposes you to further fraud.
  • Do not send card photos over chat apps or social media.
  • Do not ignore small test charges. Fraudsters often run a small charge before a larger one.
  • Do not use the same password across shopping, email, and banking accounts.
