Someone opened a credit card in my dad’s name two years ago. He found out when a collections notice showed up for $2,400 at a store he had never visited. The cleanup took months — phone calls, affidavits, disputes with three credit bureaus. All of it could have been prevented by something that takes 20 minutes and costs zero dollars.

A credit freeze blocks anyone — including you — from opening new credit accounts in your name until you unfreeze. It is free, it does not affect your credit score, and it is the single strongest protection against identity theft available to every American.

Freeze vs. Lock vs. Monitor

These are not the same thing:

• Credit freeze: Legally required to be free. Blocks all access to your credit report for new applications. Strongest protection by law.
• Credit lock: Marketing product offered by credit bureaus. Convenient but not legally binding. Often bundled with paid services.
• Credit monitoring: Tells you after something happens. Useful but reactive. Freeze is proactive.

You want a freeze. Not a lock, not monitoring. A freeze.

How to Freeze at All Three Bureaus

You must freeze at each bureau separately — freezing one does not freeze the others:

1. Equifax: equifax.com/personal/credit-report-services
2. Experian: experian.com/freeze
3. TransUnion: transunion.com/credit-freeze

Each takes about five minutes. You will create an account, verify your identity with a few questions about old addresses or loans, and click “freeze.” Each bureau gives you a PIN or password — save these somewhere you will not lose them. You need them to unfreeze.

When to Unfreeze

Unfreezing is just as easy and usually instant or takes under an hour. You need to unfreeze — usually just at one bureau — before applying for a credit card, car loan, mortgage, apartment rental, or new utility account. You can set a temporary thaw that refreezes automatically after a date you set.

The mild inconvenience of unfreezing for a car loan once every few years is nothing compared to the nightmare of fighting fraudulent accounts you never opened.
