A background check is a procedure used by an organisation or individual to make sure that a person is who they say they are. It offers the chance to examine and validate the accuracy of someone's criminal history, educational background, work history, and other past actions.

Different nations, businesses, and people have different reasons for doing background checks and different levels of legitimacy.

Usually conducted when a candidate applies for a job, an employment background check can also be conducted whenever the company feels it is essential. These checks are carried out using a range of techniques, such as in-depth database searches and personal references.
