A Student ID is a unique identification number assigned to each student by an educational institution. This number helps schools and universities keep track of students' records, including grades, attendance, and personal information. It is often required for various administrative tasks, such as registering for classes or accessing online resources. Students typically receive their Student ID upon enrollment and must use it throughout their time at the institution. It is important for maintaining privacy and security, as it allows schools to manage student data without using personal information like names or social security numbers.
