Another university is dropping Social Security numbers as student identifiers. The new system kicks in after Memorial Day for Southern Illinois University, which will then identify a student by a random generated number.

The new ID numbers are part of the larger process of converting to a new student information system, which should be implemented by the fall of 2009, says a school administrator.

Social Security numbers aren't disappearing entirely. They will still be used by the university, but only for financial aid and payroll purposes. Read more here.
