Identity Theft: Freezing Your Credit
Freezing your credit is something every American should do. Hard stop. Period. End of story. And if you have kids, do it for them, too. It literally costs nothing.
Freezing your credit is exactly what it sounds like: you sign up for a credit freeze, they send you a PIN (don't lose this PIN), and then nobody can open an account without your PIN. It's like multifactor authentication for your credit. As an added bonus, they send you a letter whenever your credit changes, such as an adding an address or account inquiry. Freezing your credit must be done on individually with each credit union: Equifax, Experian, TransUnion. As I said, each time they will issue you a PIN, don't lose it.
Unfortunately it doesn't stop there. Some people have discovered that one can work around a freeze with enough cleverly-gathered information, so make sure to place a fraud alert as well, which adds yet another layer of security to your credit. While freezes last indefinitely, fraud alerts need to be placed once every year, so make sure to set a reminder. The good news is, they only need to be placed with one agency, and the alert will be passed around to the others, so that cuts your work in 1/3.
If you think this sounds like a lot of unnecessary work, then clearly you're lucky enough to have never been the victm of identity theft. No matter how bad your credit, I promise I can find someone willing to open a high-interest credit card in your name, and then I can sell whatever I buy from them and I don't have to worry about the interest rate or payments because I don't plan to honor them. Now it's on you to go through the headache of proving that it wasn't you, and I promise you it's a nightmare.
