My third oldest card is an AT&T Universal Visa card, now issued by Citibank. It will have been open for 30 years come April, dating to 1990. Apart from helping my credit score by providing a long credit history, the card does nothing for me. I put enough occasional spend on it t keep it active but get nothing else from it.
Citibank has made an offer to convert it to a Citi Rewards+ MasterCard. I've checked and this card will not be very useful for me, but its value is an improvement, however slight, over the Universal Card, which offers no benefits or rewards I use.
My only concern then, is that my account age remain the same. I'm pretty sure it will. I know when I had a Citi Hilton Visa card and Hilton switched all its business to AmEx my Citi Hilton card was automatically converted to an Amex card and its credit history remained intact. So I believe converting this card within City, but switching Visa to MC, should be fine. But because the added benefits are so small, I don't want to take any risk. Does anybody know how I might be able to determine with certainty that the converted card will inherit the history of the existing card?
