Got a Data Breach Notice in the Mail? Here's What It Means and What to Do Next

An envelope arrives from a company you barely remember doing business with. Inside, a letter says your name, address, or even your Social Security number was exposed in a "data breach." It often ends with an offer of free credit monitoring. It's natural to feel alarmed, and just as natural to toss it in the recycling. Neither reaction is quite right. Here's what is actually true, and what to do about it.

What a data breach actually is

A data breach happens when someone who shouldn't have access gets into a company's records. Think of a store whose back-office filing cabinet gets broken into. You did nothing wrong; the company that stored your information was the one that failed. The letter is the company telling you what was in that cabinet.

Getting a letter does not mean your identity has been stolen. It means your information is now in the hands of people who could try to misuse it. That's a risk to manage, not a disaster that has already happened.

Step 1: Read what was actually exposed

The letter should list the types of information involved, and this matters a great deal. An exposed email address means you may get more spam and phishing. An exposed password means you should change it. An exposed Social Security number or date of birth is more serious, because those details can be used to open new accounts in your name. Match your response to what the letter says was taken.

Step 2: Make sure the letter is real

Scammers know breach letters make people nervous, so fake ones exist. Be suspicious of any notice that pressures you to act today, asks you to send your Social Security number or a payment, or points you to a website you don't recognize. Instead of using a phone number or link in the letter, look up the company's official website yourself and find its breach notice there.

Step 3: Freeze your credit (it's free)

This is the single most powerful step. A credit freeze locks your credit report so that lenders can't open new accounts in your name. According to the Federal Trade Commission, it is free to place and free to lift, it doesn't hurt your credit score, and it stays in place until you remove it. Think of it as a deadbolt on the door that thieves would use to take out loans as you.

To do it, contact each of the three credit bureaus: Equifax, Experian, and TransUnion. You can do this on each bureau's website or by phone, and it usually takes about ten minutes each. Write down any PIN or password they give you and keep it somewhere safe. When you later apply for a credit card, a loan, or a car, you can temporarily lift the freeze with just the one bureau the lender will check, then freeze it again afterward.

You may also hear about a "fraud alert." That's a milder option: it asks lenders to double-check your identity before opening new credit. It's also free, but a freeze is stronger, so it is usually the better choice after your Social Security number is exposed.

Step 4: Tidy up your passwords

If a password was involved, change it on that site right away. Then change it anywhere else you used the same one, because thieves routinely try stolen passwords on other popular sites. Using a different password for each important account keeps one company's mistake from becoming yours everywhere.

Step 5: Keep an eye on your accounts

For the next several months, glance at your bank and credit card statements for charges you don't recognize. You are also entitled to check your credit reports for free, and reviewing them for accounts you didn't open is a smart habit. The free monitoring the company offers can help too, but it only alerts you after something happens, while a freeze helps prevent it, so don't treat the offer as a substitute.

If something does go wrong

If you find an account you didn't open, or someone has used your identity, go to IdentityTheft.gov, the government's official site. It walks you through a free, personalized recovery plan, including the letters to send and who to call.

The short version

A breach letter is a warning, not a verdict. Check what was exposed, confirm the letter is genuine, freeze your credit at all three bureaus, refresh any affected passwords, and watch your statements. None of it costs money, and most of it takes less than an hour.
