 TITLE: What Is a CVV Number on a Credit Card? CONTENT: The Bottom Line\n---------------\nAll credit cards and debit cards now have CVVs on them as a measure to help ward off fraudulent purchases made online or by phone. And while a CVV or CID code is harder to access than your card number, it doesn't guarantee protection. They certainly help, but they aren't foolproof, so it's still important to take steps to protect yourself. It's wise to use identity theft monitoring so you'll know right away if there's any unauthorized access to your accounts. END
