A requestion regarding different companies of CC

As some of you know, my credit history is pretty young (close to two years)

I've always paid in time, never go over the limit nor maxed out a card.

Right now I own some Mastercards and Visas. I got approved for a 0% transfer balance for 12 months. It's an American Express with Bank of America.

Does the fact that I have now a Visa, a Mastercard and an American Express, will my credit increase more or Will it build stronger? It's like I have credit cards with the three main companies.


Thanks.

You're on the right track. Your cards are from prime issuers which is good. It's a question of giving time time. You need to let them age and build history.
