Dear Liz: I implemented a credit freeze a few months ago. I’m wondering if that could prevent me from having credit scores. I understand that if you don’t use credit, your credit scores can basically go away. I don’t have any loans or a house payment. I do have a few credit cards, used often and paid in full monthly.

Am I at risk of my credit fading away because of neglect with the freeze in place?

Answer: You’ll continue to have credit scores as long as you keep using credit accounts that are reported to the major credit bureaus. The people who are at risk of having their credit die of neglect are the ones who stop using credit.

About 7 million people are considered “credit retired,” which means they no longer actively use credit enough to generate credit scores, according to credit scoring company FICO. Their histories are free from charge-offs and other negative marks that might indicate their lack of credit is involuntary, says Ethan Dornhelm, FICO’s vice president for scores and predictive analytics.

Being credit retired can be costly. People may be shut out of loans they want in the future, or may have to pay higher interest rates. A lack of scores could lead to higher insurance premiums, cellphone costs and utility deposits.

Keeping your credit scores alive is relatively easy — using a single credit card is enough. There’s no need to carry debt or pay interest. Just continue using the card lightly but regularly, and pay it off in full every month.

Your credit freezes will prevent new lenders from seeing your scores and opening new accounts in your name unless you thaw the freezes. Companies where you already have an account, however, will be able to see your reports and scores.
