Now that the FCC is cracking down on robocalls, scammers are turning to a low-tech way to fool people into giving up private financial information -- letters sent in the mail.

You've probably heard that the IRS will never ask for your personal information over the phone, and that's still true. But what if you got a letter in the mail?

This photo is making the rounds on Facebook, and the letter, which looks like an official bill -- is a fake.

Remember, if you owe money to the IRS, you would get an audit notice first. If you're unsure about the validity of letters coming to your home, don't call the number on the letter -- call the organization directly.
