An applicant may prove sufficiently the existence and validity of his Social Security number, for purposes of Section 14-7-130, by any document or electronic means considered reliable by the Department of Motor Vehicles, so long as that document or electronic mean does not conflict with other provisions of state or federal law. The numbers also may be obtained from the Department of Revenue pursuant to Section 12-54-240(B)(7), which permits the Department of Revenue to submit taxpayer Social Security numbers to the Department of Motor Vehicles and to the State Election Commission.
This section does not prevent issuance of a driver's license or identification card to a foreign exchange student participating in a valid foreign exchange program.
If any one of the above documents does not show a link to the applicant's evidence of full legal name, the department may require the applicant to submit more than one document to show traceability from the applicant's original name to his current name.
