Dear Liz: I have a long-standing credit card with a national bank. As I travel a lot, I just opened a travel rewards card with the same issuer. I would prefer to keep the new card and close the old one, rather than keep two cards active with the same issuer. I understand from reading your columns this might (temporarily?) lower my credit score. Any other downside?
Answer: It’s hard to predict how an account closure will affect credit scores or how long the impact will last. The effect is likely to be greatest for people with few credit accounts and short credit histories. You may be able to mitigate some of the damage by asking that the credit limit from the old card be transferred to the new one.
Before you do that, however, consider why you’re averse to having two cards with the same issuer. The old card may have benefits the new one lacks, and could be a helpful backup if your new card is lost or compromised. The case for keeping the old card is strengthened if the annual fee is low or nonexistent. Just remember to use the old card occasionally to minimize the chances the issuer will close it for you.
