INVESTOPEDIA EXPLAINS 'Account Number'

At one time, it was common to use a Social Security number as the primary identifier, particularly for employees (for payroll or human-resources identification). Because of the proliferation of identity theft, however, this practice has been all but eradicated. It is not a good idea to use a Social Security number for any type of account, or as a user name or password for electronic identification.
