DMV Social security number (SSN) requirement

The Social Security Act allows any state to use the SSN to establish the identification of an applicant. The California Vehicle Code requires the collection of the social security number.

All applicants must submit to DMV their social security number. Evidence of your social security number is required only on applications for an original commercial driver license and any request to correct a SSN that is already on the driver record data base, regardless of the class. The SSN is considered confidential and will not appear on the photo license or be encoded on the magnetic stripe. Any documents that the department is authorized to release to the public will have the SSN masked. The SSN is electronically verified with Social Security Administration while you are in the DMV office for all DL/ID card transactions, if it has not already been verified.

The only documents acceptable for SSN verification are originals of the following:

  • Social Security Card (cannot be laminated)
  • Medicare card
  • U.S. Armed Forces Identification Cards:
    Active-DD 2
    Retired-DD 2
    Reserved-DD 2
    Dependent-DD 173
  • Military separation document-DD 214

Exception to the SSN requirement:

If you are legally present in the US, but ineligible for an SSN, you are exempt from SSN requirements. However, you must still provide an acceptable BD/LP document for any DL/ID card application OR provide a valid SSN.
