Search for Duplicate SIN Numbers

When setting up employees you may have inadvertently assigned the same social insurance number to more than one employee, or you did not enter the number, leaving it as zeroes. To report employees with the same social insurance numbers use the Find Duplicate SIN feature.

Searching for Duplicate SINs

1. From the Payroll Periodic Processing folder, select Find Duplicate SIN.
2. Click Proceed.
3. If duplicate social insurance numbers are entered for any employees, you can click Print to generate the Duplicate SIN Listing report, which lists these employees.
   Note:

   Note: To include full (not masked) social insurance numbers in the report, select the Show SIN Numbers option. If you do not select this option, SIN numbers in the report are masked, so only the last part of the number appears (for example, ***-***-123).

Reporting

The Duplicate SIN Listing report helps you identify employees who have been assigned the same social insurance number. You should assign a unique social insurance number to each employee before you start year-end processing and reporting, such as generating T4 or Relevé 1 slips.
