The best way to build your credit history is to have active accounts, open for as long as possible.
Get credit
If you don't have any accounts, consider getting a credit card. Check your offers to see what is available to you. To see offers might be relevant for you, make sure the details we have for you are correct.
Use credit and pay on time
Using a credit card and paying it off on time every month (in full if possible) can improve your credit score. Always stay within your means, spending only what you can pay back in full.
This shows that you're stable and able to pay back what you borrow. Over time, it builds your credit history, which impacts your score.
