A background check is a process used to verify a person's identity and gather information about their history. This can include checking criminal records, employment history, and education credentials. Employers often conduct background checks to ensure that potential employees are trustworthy and qualified for the job. Individuals may also request background checks for personal reasons, such as screening a new tenant or a potential partner. These checks help people make informed decisions by providing insights into someone's past, ensuring safety and security in various situations.
