where do i find my credit card balance and advailable credit?

Do you have internet banking?

If you do, most likely you can check online when you log in to your bank account.

Otherwise, walk into your bank branch and check over the counter.

Some banks make it difficult even when you log in to your account correctly. Your balance and credit line might not be clearly labeled as such, but if you see a dollar amount followed by a dividing symbol and then another round number, then that is probably it. Call you credit card company if you still are having difficulty.
