Credit Score is computed by Credit Information Companies. In India following four companies calculate credit score– CIBIL, TransUnion, Experian, Equifax and High Mark
When you make a transaction—the one that is relevant to determine your score—banks send details about it to all four credit bureaus. To send details to all credit agencies is a mandate by the RBI. Essentially, banks keep Credit Information Companies up-to-date about your monetary habits. If a bank needs to check your Credit Score, they can approach any one of the bureaus. It doesn’t matter which one because all will have the same score for you– all four are equally authoritative and on par with each other.
After receiving information from the bank, credit bureaus get down to the task of collecting more information about your financial habits from other banks and financial institutions. The credit bureaus then process this information to formulate what is called a Credit Report.
Though the processes followed to compute your score might differ from agency to agency, your Credit Score calculated by all will be the same. This is because banks intimate the relevant information to all four agencies. Therefore, no matter which agency a bank picks to check your Credit Score, there will be no major discrepancy in it.
Of the four agencies, CIBIL, however, is the most popular since it was one of the first Credit Information Companies to start operations in India. This has fuelled the notion that CIBIL Score is more accurate than a score from other agencies. This, however, is not true. Banks give equal weight to scores from all four agencies. Equifax, Experian and High Mark Credit Scores are as good to banks and other financial institutions as CIBIL Score.
