A few years ago, credit scores were taboo. The idea that a credit score could be used for more than just determining qualification for a loan was at best unfair and at worst discriminatory. Employers in some circumstances can use credit scores or credit reports to determine whether to offer jobs to applicants. If you sign a credit authorization form, which some employers might imply or outright say is necessary to be considered, the company can use your credit against you.
Auto insurance companies can use credit scores to set your rate because they’ve found that there is a correlation between higher scores and safe driving. If you intend on renting an apartment, the landlord can choose to perform a background check, and credit history could be included.
