Quick answer Freezing your credit blocks access to your report, so nobody can open a card or loan in your name. It is free by law, it does not lower your score and it does not affect accounts you already have. You have to do it at all three bureaus (Equifax, Experian and TransUnion), each one separately, and you can unfreeze for free when you apply for credit. It is especially useful if you have just arrived and do not check your report often yet.
If someone gets hold of your details and opens a card in your name, the problem is not just the money: it is that you find out months later, when the debt is already on your report and you have to prove it was not you. Freezing your credit is the tool that stops that from happening, it is free by law, and a great many people do not know it exists.
What it actually does
A credit freeze blocks access to your report. When a bank receives an application in your name and goes to pull your history to decide, it finds the door shut. And without being able to assess you, it approves nothing.
That is the key difference from other measures: it does not warn you that something happened, it prevents it.
What it does not do
Worth being clear so there are no surprises:
- It does not lower your score. Not one point. Freezing and unfreezing leaves no trace on your history.
- It does not affect accounts you already have. Your current cards keep working normally.
- It does not stop you checking your own report or getting your score.
- It does not protect against everything. If someone uses an existing card of yours, a freeze will not stop it; that is handled through the bank’s protections.
You have to do it three times
This is where almost everyone stops halfway. There are three main credit bureaus — Equifax, Experian and TransUnion — and each is a separate company with its own report.
Freezing at one is not much use: the bank being used to impersonate you might pull either of the other two. You have to freeze at all three, separately, creating an account on each site or calling them.
It is half an hour the first time and then it is done.
It is free, and that is the law
Since 2018 federal law requires freezing and unfreezing your credit to be free at all three bureaus. If someone charges you for this, you do not need them.
One thing to watch: there are paid products called “credit lock” that the bureaus sell as a subscription. They work similarly but they are a commercial service, not the legal right. The free freeze is the one you want.
Unfreezing when you need to
The usual objection: “what if I want to apply for a card?” You unfreeze, and that is it.
- Log into the bureau’s site with your account, or call.
- You can unfreeze completely or just for a few days, which is the convenient option if you have a specific application coming.
- You can also unfreeze only at the bureau the bank is going to pull, if they tell you which.
- It refreezes on its own if you set an end date, or you do it yourself when you are done.
Online it is usually a matter of minutes. Keep the PIN or login details they give you: you will need them.
Freeze, fraud alert, or nothing
- Freeze: genuinely blocks. It is the strongest option and it is free. Sensible for almost everyone, especially if you are not applying for credit soon.
- Fraud alert: does not block, it only requires the lender to verify your identity more carefully. Weaker, also free, and lasts a limited time.
- Nothing: what most people have, and the reason identity theft is still so common.
Especially important if you just arrived
When your report is empty or barely started you are an easy target: there is no prior activity to contrast anything odd against, and you do not yet have the habit of checking your history.
Freezing before you start building credit, and unfreezing briefly each time you apply for something, is a cheap habit that avoids a very expensive problem.
