If a scammer gains access to your personal information, they could open fraudulent credit accounts in your nameâborrowing money or opening credit cards, for example. One swift way to prevent that: Freeze your credit and halt scammers in their tracks.
Putting a freeze on your credit is a powerful way to deter criminals from committing identity theft and fraud. Even if a hacker obtains personal data like your Social Security number, having a security freeze in place with all three credit bureaus helps stop anyone from opening an account in your name without your permission.
Freezing your credit is relatively easy to do, free of charge, and it wonât harm your credit history at all. (Unfreezing your credit can be time-consuming, but more on that below.) Hereâs how a credit freeze helps protect you:
You decide when to place a credit freeze and when to lift it. If youâre not in the market for a loan or a credit card, you can leave a freeze in place for as long as you like.
You can still use all your current accounts as you normally would. A credit freeze only affects new accounts.
When you need access to your creditâfor a car loan, say, or to rent an apartmentâyou can unfreeze the account at no charge and set up the new, legitimate account. Just remember to thaw your credit before you try to open a new account.
You can lift a freeze temporarily or permanently. A temporary thaw can allow businesses to check your credit within a set window of time before the credit automatically re-freezes. Just be sure to select an interval that allows the bank or other institution enough time.
Again, a freeze has no impact on your credit history or report.
Setting up a credit freeze is relatively simple:
In all cases, keep your passwords and PINs where you can find them later when you need to unfreeze your credit.
A credit lock sounds similar to a credit freeze, but itâs a different service.
According to federal law, the credit bureaus must offer free credit freezes to consumers. A credit lock also blocks access to your credit report, but itâs a service offered by the credit bureaus and may come with a fee.
When you need access to your credit report for your own purposes, you can lift the freeze, either permanently or temporarily. Remember to plan ahead so you donât run into any roadblocks in setting up a new cell phone, for example.
Thawing your credit requires similar steps and information. To unfreeze your credit online or by phone, youâll need your password and/or PIN to access your online profile with each bureau. These are the fastest ways to unfreeze your credit, taking about an hour.
Unfreezing a credit report via mail takes more timeâthree days from the time the credit bureau receives your request.
As with any financial strategy, it pays to weigh the advantages and disadvantages of using a credit freeze.
Pros:
Cons:
Did you know that you can see your own credit report once each year for free? This programâmandated by federal lawâoffers information from all three credit agencies. Choose from one of three ways to access your report:
Check your credit report at least annually to ensure itâs accurate. Errors can drag down your credit score.
With incidents of identity theft on the rise, and hackers getting more sophisticated at every turn, it makes sense to consider all the options when it comes to protecting yourself, your identity, and your credit history. Although it does take some effort to implement a credit freeze, itâs a light lift compared with the financial problems that can result from identity theft and fraud.
Itâs also important to remember that if you decide to freeze your credit, youâre in the driverâs seat. You can lift the freeze, permanently or temporarily, at any time, at no charge, and with no impact on your credit history or score. A credit lock offers similar protections, but may come with a fee, and may not be as effective.
