Can I Change the Name of My Business?

i want to keep the age of my l elsi, as well as my credit card that i opened up inth llc. Even though i haven't done anything with it yet. I thought if i just changed the snake's code in the name, i could do it. But i'll research ask some more. My other question is, so for the credit cards that we apply for right i used a your chips as well on one of our calls,. And i was able to get a couple of amax cards, and i got my chase ink cards. So dos it? Is it the same if you apply for a credit cardin your business name and you're the personal gu
