The last couple years (2014-2016), it became common for third party recruiters to ask job candidates four or five last digits of their Social Security Numbers (SSN) or the whole SSN and Month and Day of their Birth (sometimes and Year of Birth) under pretext of avoiding double submissions.

I always believed that it could be necessary only on the final steps of hiring process, however very often I yielded their nice voices promising such great opportunity surely coming.

Yesterday I've found a new collection account in my credit report based on some Car Title Payday Loan with unknown me business and which I never borrowed.

So, I am strongly advising all job seekers never ever giving away to recruiters any part of their SSN and Date of Birth (DOB) unless it's coming to real hiring which materialized for me just once (in December 2015 for six months contract).
