ID theft is the fastest-growing crime in the United States, according to authorities. About 10 million people a year find themselves in trouble involving their identity.

In many cases, thieves who take your personal data have a job where they have access to the information. Other sources include bribing someone who has the access, stealing the data from a computer or even a laptop, stealing mail, wallets or bank records, searching trash and one of the most recent trends: phishing.

One of the main tools of identity thieves is your Social Security number. That nine-digit code can give them access to tax records, allow them to open bank and credit card accounts, buy a car or even give your name in an arrest by authorities.

Here are a few tips on how to protect yourself from becoming a victim.
* Don't carry your Social Security card. Leave it in a safe place.
* Order copies of your credit report. You are entitled to a free report every 12 months.
* Shred documents that have personal data, such as bank account statements and credit card applications.
* Place your outgoing mail in postal collection boxes instead of your home mailbox.

Tips: What To Do When Your Identity Is Stolen
