Validating social security cards
For your protection, we do not store any social security number entered on this page.
A Social Security Number (SSN) consists of nine digits, commonly written as three fields separated by hyphens: AAA-GG-SSSS.
Enter a social security number to validate that it is in the correct format.
Additionally, we will tell you what state issued the social security number.
The central, two-digit field is called the "group number".
As a business, you must have an authorized workforce to avoid governmental fines, penalties, and sanctions.
As an individual, you may want to verify your own SSN to be sure that any applications you submit will not be held up.
The final, four-digit field is called the "serial number".
The process of assigning numbers has been changed at least twice. Before 1972, numbers were assigned by field offices; since 1972, they have all been assigned by the central office.
