Equifax FICO Score ranges from 250 to 900.
That's not a FICO score. That's Equifax's proprietary score. The FI in FICO stands for Fair Issac, the creator of the FICO score. I assure you their scores range from 300 to 850. See the link below (or the data from the link I posted).
I cannot tell you exactly how they compare, but there are industry specific scores from third parties, some range to 900, some go to 1000. The Equifax website specifically states their scores range to 850.
There are only really two scores that matter when getting credit, they are the FICO score and the VantageScope score. Anything else is a pretender to the throne, as in they wish they were Fair Issac. You want to be known for good credit, then pull a 800 or higher true FICO score.
If anyone tells you they are the same....they are not.
Both the Equifax Credit Score and the FICO Score are general-purpose score models used to predict credit risk. The Equifax Credit Score is a proprietary model created by Equifax. The FICO Score is a proprietary model created by Fair Isaac Corporation (FICO) . All Equifax consumer services and tools make use of the Equifax Credit Score unless otherwise indicated.
The Equifax Credit Score uses a numerical range of 280 to 850, where higher scores indicate lower credit risk. The FICO Score uses a numerical range of 300 to 850, where higher scores also indicate lower credit risk.
The Equifax Credit Score can be used to calculate a score for not only your Equifax credit file, but also your Experian and TransUnion credit files. This gives you the ability to compare your credit scores across all three credit reporting agencies, which can be useful in understanding your credit.
Though both score models predict similar types of risk, it is important to remember that because they were created independently by separate companies, they should not be expected to deliver identical scores. In some cases, an Equifax Credit Score and a FICO Score calculated at the same point in time may be similar. However, in some scenarios the scores may differ, perhaps significantly, based on how the different models calculate risk.
