NO! The social security number trace (sometimes referred to as SSN trace) is a research tool that we use at Good Egg to identify addresses, names (i.e., aliases, aka's), and dates of birth associated with a social security number. Various algorithms are employed to determine the output of the SSN trace, including but not limited to combinations containing full, partial, and wild-card database searches of first name, last name, DOB, and SSN.
The outcome of the SSN trace will indicate an approximate SSN issue date and location where the number was issued. The SSN trace may also indicate if the SSN appears on the Social Security Death Index (SSDI).
All that said, the SSN trace is not a social security number verification. The search does not confirm that the social security number is associated to the candidate, nor does it confirm that the candidate is eligible to work in the United States.
The only authorized pre-employment method to confirm that a social security number is valid and belongs to a candidate is by requesting consent-based social security verification (CBSV) from the Social Security Administration.
