Tips for protecting your credit cards

Protect your credit cards and account numbers to prevent unauthorized use by taking these steps:

  • Don't give your card number over the phone unless you have initiated the call. Make sure you're giving it to a reputable company or organization.
  • Never lend your credit card to anyone.
  • Never give your credit card number to someone for a purpose you do not understand.
  • Keep a record—in a safe place separate from your cards—of your account numbers, expiration dates, and the phone numbers of each issuer. This will enable you to report a loss quickly.
  • Limit the number of credit cards you have, and cancel any inactive accounts. Carry only the cards you think you'll use.
  • If carbon paper is used, make sure you get the carbon or that it gets destroyed.
  • When you sign a sales slip, draw a line through any blank spaces above the Total line to keep other charges from being added.
  • Keep your receipts to check charges when your bill arrives. You have a right to question any unfamiliar charges.
  • Never leave your credit card in a purse or wallet that is unattended or in open view in a vehicle, even if the vehicle is locked.
  • Before throwing them away, shred any documents and receipts that show your credit card number.
  • Shred any offers of pre-approved credit cards before throwing them away.
  • If you don't receive your credit card statement on time, notify the company immediately.
