Citi is providing a version that uses a different scale:
Your FICOŽ Score is calculated based on data from Equifax using the FICOŽ Bankcard Score 8 model and is the same score we use, among other information, to manage your account. This model has a FICOŽ Score range from 250 through 900.
American Express
: Your FICOŽ Score 8 based on Experian data is the same score used by American Express. Your credit score summarizes information on your credit report into a single number that lenders can use to quickly assess your credit risk. Your FICOŽ Score is a three-digit number calculated from the information on your credit report that falls within a 300-850 range. Your Experian credit report is used to calculate the score displayed above; as information on your credit report changes so will your credit score.
