An employee ID is a unique identification number assigned to each employee within an organization. This number helps the company track employee records, payroll, and benefits efficiently. It ensures that each employee's information is organized and easily accessible. Employee IDs are often used in various systems, such as timekeeping, access control, and performance evaluations. By using these IDs, companies can maintain security and streamline processes, making it easier to manage a large workforce while ensuring that each employee is recognized individually.
