Q&A: Credit cards just keep coming

Dear Liz: I use only two credit cards. But I have several credit cards I never use. When the cards expire, the issuers send me new ones. I just received two more cards, with new expiration dates, which I will not use. I keep hearing that cancellation of cards results in lower credit scores. How can I cancel all the unused cards I have without affecting my 797 score, and how can I stop them from sending me new ones without my authorization?

Answer: Your issuers can continue sending you new cards until the accounts are canceled. Your “authorization” isn’t necessary once you’ve applied for the card. Some credit card companies will close an account that hasn’t been used in more than a year, but others will keep accounts open hoping you’ll start using the cards again someday.

Having several credit cards is typically good for your scores — of which you have many, by the way, not just one. But you don’t have to keep unwanted cards forever. If your scores are in the high 700s you can close the occasional credit card account.

What you don’t want to do is shut down a bunch of cards at once, or close your highest limit cards. Credit scoring formulas are sensitive to the amount of your available credit you’re using. Anything that significantly reduces the amount of available credit you have can hurt your scores.
