Citi doesn’t follow the same guidelines as the Chase 5/24 rule, which means with Citi you’re not limited to opening only five credit cards, including Citi cards, in the past 24 months. Keep in mind that Citi does have an unofficial 8/65 rule, which means you can apply for only one Citi card every eight days and up to two Citi cards every 65 days. If you’re interested in both Chase and Citi cards, it makes sense to apply for any Chase cards, like the Chase Freedom Unlimited, before applying for any Citi cards. This is because opening most credit cards from any card issuer will count toward your Chase 5/24 status.
