What this result tells you
This number fits the published public record for old-style Social Security numbers. The first three
digits point to Enumeration at Entry, and the group number falls inside the published range for that
area.
The year range helps place the number roughly in time. It is useful for basic checks, research,
and general context.
How the date range was worked out
This range comes from archived monthly public record updates for this area and group.
Public record window: between August 2009 and October 2009
Why this result came back
The checker compares the area number to the published area chart, then checks whether the group
number is at or below the last published group for that area.
The serial number helps confirm the format, but it does not change the location match or the broad
date range.
