The big three credit bureaus collect information about how we manage our financial obligations. The bureaus then sell this info to lenders and credit-scoring companies, which use it to help determine eligibility for loans and lines of credit. Employers, car dealers, property management companies and various other decision-makers also use data from the three credit bureaus to evaluate applicants.
Another difference you may see is the way the credit agency records, displays or stores your data. Again, this is just a slight difference and shouldn’t cause any issues in your overall credit profile.
