Issue/Introduction

My Social Security number is not matching. Is the SSN valid?

Resolution

The solution is for DLP version 7.0 and above:

The Data Identifier for Social Security Numbers checks to see if the first 5 digits are currently used codes.  There are many sites available on the web to test if a Social Security Number is valid -

The structure of the Social Security Number is defined:

http://www.socialsecurity.gov/history/ssn/geocard.html

  • The first set of three digits is called the Area Number
  • The second set of two digits is called the Group Number
  • The final set of four digits is the Serial Number

The Area Number, the first three digits, is assigned by the geographical region.

The Group Numbers range from 01 to 99. However, they are not assigned in consecutive order. For administrative reasons, group numbers are issued in the following order:

  1. ODD numbers from 01 through 09
  2. EVEN numbers from 10 through 98
  3. EVEN numbers from 02 through 08
  4. ODD numbers from 11 through 99
  • The last four digits are serial numbers. They represent a straight numerical sequence of digits from 0001-9999 within the group.

 Effective June 25, 2011, the SSA assigns SSNs randomly and allows for the assignment of area numbers between 734 and 749 and above 772 through the 800s

 

Note: Changes to the Social Security Numbers were made in June 2011.  There is a custom Data Identifier for version 11.0 and above available in Custom Data Identifier for Randomized Social Security Numbers ( SSN ).
