Steps to Find Duplicate Social Security NumbersThe Find Duplicate Social Security Numbers option accessed within the Employee W2s option in Payroll is used to check for duplicate W2s to the same employee (W2s with the same social security number). The Find Duplicate Social Security Numbers option is executed automatically after generating W2s and when accessing the Employee W2s option for previously generated W2s; however, the option can also be accessed under the Options menu within the Employee W2s option as needed.
