You may have been requested for the last 3 digits of your SIN. We would like you to know that we are extremely conscious of your security, and take numerous measures to ensure we protect your personal information.
Some of our clients (mostly the big banks) have internal Applicant Tracking Systems(ATS) to view and monitor all candidates submitted to them. They use the last 3 digits of your SIN as well as month and day (mm/dd) of your birth to create a unique identification for you in their system.
Upon submitting your profile, this unique identification number provides the employer access to your profile and all of your job application history you may have had with them.
This unique identification number is also used to set up candidate login into Client's ATS during on-boarding.
