While it's not strictly necessary to track all of your credit scores, it can be helpful to monitor your FICO score and Vantage Score and any other credit scores that lenders and financial institutions may use. This is because different lenders and financial institutions may use different credit scoring models to assess your creditworthiness.
Monitoring your credit scores can help you keep track of your creditworthiness over time and identify any changes or errors on your credit report that could be affecting your scores. It can also help you to better understand how lenders view your creditworthiness and can help you to identify areas where you may need to improve your credit.
You don't need to check your credit scores every day, but it's a good idea to check them periodically, like once a month or once every few months. You can get your credit scores for free from several sources, including your credit card issuer, some banks and credit unions, and through free credit monitoring services.
