Validating social security number
The final, four-digit field is called the "serial number".
The area numbers are assigned to geographical locations.
They were originally assigned the same way that zip codes were later assigned (in particular, area numbers increase from east to west across the continental US as do the ZIP codes).
Using a social security number validation is considered to be one of the most effective ways to start conducting a background check during the pre-employment screening process.
The use of a social security number allows the ability to gather specific information associated with the nine-digit identifier that is used to validate the identity of an applicant and the authenticity of their history.
We can also return the individuals name, address, former addresses, date of birth, phone number and at the same time screen the name against the U. Treasury Department OFAC and SDN lists for Patriot Act Compliance requirements.
