These tips will help protect yourself from credit card fraud.

Do:

• Sign your cards as soon as they arrive.
• Carry your cards separately from your wallet, in a zippered compartment, a business card holder, or another small pouch.
• Keep a record of your account numbers, their expiration dates, and the phone number and address of each company in a secure place.
• Keep an eye on your card during the transaction, and get it back as quickly as possible.
• Void incorrect receipts.
• Destroy carbons.
• Save receipts to compare with billing statements.
• Open bills promptly and reconcile accounts monthly, just as you would your checking account.
• Report any questionable charges promptly and in writing to the card issuer.
• Notify card companies in advance of a change in address.
• Be extra-wary while traveling. Notify your bank if you are traveling.

Don't:

• Lend your card(s) to anyone.
• Leave cards or receipts lying around.
• Sign a blank receipt. When you sign a receipt, draw a line through any blank spaces above the total.
• Write your account number on a postcard or the outside of an envelope.
• Give out your account number over the phone unless you're making the call to a company you know is reputable. If you have questions about a company, check it out with your local consumer protection office or Better Business Bureau.

Reporting Losses and Fraud

If you lose your credit or charge cards or if you realize they've been lost or stolen, immediately call the issuer(s). Many companies have toll-free numbers and 24-hour service to deal with such emergencies. By United States law, once you report the loss or theft, you have no further responsibility for unauthorized charges. In any event, your maximum liability under federal law is $50 per card.

After reporting fraud, you may be asked to sign a statement under oath that you did not make the purchase(s) in question.
