If you have lost your credit card or fear it may have been stolen, notify the issuer of the card as soon as possible. Under US law, once you have notified the credit card company that your card is lost or stolen, you are not responsible for unauthorized charges. Your liability for charges on a lost or stolen card is limited by law to $50.

Although many people are aware of this, still unscrupulous scamsters may try to sell you credit card loss insurance protection. Using telemarketing schemes to sell worthless insurance, these scamsters can cost consumers dollars to protect what is already protected by law. Often they will tell people that the law has changed, and they are now responsible for all unauthorized charges.

The best defense you have against scam artists is knowledge. When you hear someone telling you something that doesn’t agree with what you know, be on your guard. Read your credit card agreement and know the terms of your account and procedures for dealing disputed charges. List your phone number on the National Do-Not-Call Registry. Remember, never give out your account number, social security number or any other personal information over the phone unless you are sure of the business that you are dealing with.
