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 March 2011 and April 2011

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.

About this result

This page checks the number against the public record, not a live Social Security Administration system.

It can help you screen a number and place it roughly in time, but it does not confirm identity or ownership.

Older numbers use wider date ranges because exact issue dates are not published for general lookup.

What was checked

1. The format rules for the area, group, and serial numbers.

2. The likely state or territory tied to the area number.

3. The public record range for that area and group.
