You stop receiving mail or emails

On the other hand, not receiving mail or emails related to expenses could also be a sign of identity theft. This especially goes for items that you receive on a regular basis, like bank statements and bills. An identity thief only needs your name and address to re-route your mail and intercept sensitive documents, so make sure to follow up with creditors if your bills don’t arrive on time.

You are told that you filed more than one tax return

Strange, but true—identity thieves can file a tax return in your name, claiming a phony refund and hoping to swipe it from your mailbox. Being rejected for an electronically filed tax return or receiving a tax refund you did not request are big red flags that your identity has been stolen. If this happens to you, Weisman recommends contacting the IRS as soon as possible to report the fraud.

If you start getting mail addressed to people who don’t live with you, you should take it seriously. Mistakes happen, but it can’t hurt to freeze your credit if it does end up being identity fraud. “Everyone should do this regardless of whether they are a victim of identity theft or not,” Weisman says. “It is the single best thing you can do to protect yourself from becoming a victim of identity theft.”
