What is a credit check? A credit check is an examination of the financial background and behaviour of the subject of the check. As part of the credit check, companies may want to know how you paid back previous loans, for instance, or how often you made late repayments. Banks, landlords, utility providers and some employers might require a check on an individual. Business owners are likely to request a credit check on another business if, for instance, they are considering a joint venture, taking on new suppliers, or new vendors. Such checks may reveal late payments, bankruptcies, judgements, and liens.
