When did the concept of credit scores come into existence?

At what point in history were “credit scores” created, and who thought of them? Also, who agreed on the numbers? Did financial institutions get together and come up with a number system?

However, credit reporting and credit scores are not the same thing.

I believe some American outfits - Fair Isaac? - created credit scoring systems.

Anyway, arose out of credit reports and it wasn’t the banks that thought up or created either. There is not one unified approach or scoring system either.

Fair Issac’s FICO score dominated for a long time. Plus, Each agency can sell their own score and lenders can buy a score w/a report or run their own scoring model and combine other factors that are not on a credit report (income, length of time at job, etc). Mortgage scores are specific to loan type. It varies.

Still, when credit scores where ignored during the whole sub-prime lending fiasco and general mortgage collapse, that pretty much did more than several billion dollar’s worth of PR for credit reporting and credit scoring.

This wouldn’t be the best time in history to question credit scoring or reporting.

Fair, Isaac, and Co. was founded in 1956, and marketed their first credit scoring system in 1958. AFAICT, this is the first credit scoring system. They introduced the first behavior scoring system (for predicting credit risk) in 1975, by which time credit scoring was mainstream. FICO, while having its own models, will also produce scoring according to customer models or priorities, so there is less uniformity in credit scoring than you might think. Also, lending institutions can (and do, and many more used to) do their own credit scoring from credit reports. Credit scores are also used by insurance companies and other underwriters of various types. The credit reporting bureaus offer their own scores, etc.
