The most important difference between the various credit scoring websites is the frequency with which the credit scores are updated. Most credit scoring websites offer monthly or weekly updates -- WalletHub is the only site that offers daily updates. It’s also useful to know which credit reporting agency the websites obtain their credit scores from. You can find all you need to know in WalletHub’s 2018’s Best Credit Score Site report, at: https://wallethub.com/best-credit-score-site/. Hope this helps.

Only one website is authorized to fill orders for the free annual credit report you are entitled to under law — annualcreditreport.com. Other websites that claim to offer “free credit reports,” “free credit scores,” or “free credit monitoring” are not part of the legally mandated free annual credit report program. In some cases, the “free” product comes with strings attached. For example, some sites sign you up for a supposedly “free” service that converts to one you have to pay for after a trial period. If you don’t cancel during the trial period, you may be unwittingly agreeing to let the company start charging fees to your credit card.
