Use our free tool allows tap into our extensive database and find out if a Social Security Number is valid and whether or not it has been issued. This tool cannot be used to validate employee and non-employee Social Security Numbers. Using our Social Security Decoding information we are able to determine when and where a social security number was issued as well. This data was collected from the Social Security Administration's Highest Issued Group data and was updated until the Social Security Randomization policy took effect in June 2011.
