Is the SSN required to obtain a driver license? NO!
Is the SSN required to obtain a USA Passport? NO!
The good news is that the Office of Manage and Budget pursuant to the Paperwork Reduction Act of 1980, has indicated that there must be a requirement for a benefit before an Agency can require an SSN. Otherwise, your decision to furnish an SSN is voluntary and not mandatory.
Passport and driver licenses are not benefits issued by the state Federal governments. They are rights derived from your constitutional right to travel.
The Privacy Act regulates the use of SSNs by government agencies. They may require an SSN only if a law or regulation either orders or authorizes them to do so. Agencies are required to disclose the authorizing law or regulation. If the request for an SSN has no legal basis, the person may refuse to the SSN and still receive the agencies services.
The bad news is the laws are deliberately written to obscure that fact and to appear that they are requirements. The trouble is you will be dealing with clerks that are trained to go by the appearance of the law and have no training in actual law.
Therefore, if you don’t provide the SSN they may refuse to issue the documents. Unless, you are willing to escalate the issue to the management level and in some cases hire an attorney, as a practical matter it is best to consider the SSN to be a requirement. Even more so, if you are using are attempting to acquire a alias or new identity.
Since this web site is about obtaining a new identity, demanding your right to not provide an SSN would raise a red flag resulting in additional investigation that you might want to avoid. Therefore, within the various pages of this website, when I am discussing the issue of an SSN, I will consider the SSN to be a requirement if the agencies state that an SSN is required and do not indicate that there are exceptions.
Nevertheless, some state such as Texas have gone off the deep end with listed requirements that are totally unreasonable. However, perhaps that is because they are a border state with Mexico. Nevada is far more reasonable. In Nevada the form you must fill out gives you the option of swearing that you have never had a SSN (http://www.dmvnv.com/pdfforms/dmv002.pdf).
In that event, the driver license Nevada issues may be a non-compliant driver license. Perhaps you can't use it to fly; however, considering the extreme cruelty inflicted on people by the Nazi type that work for the Homeland Security, I wouldn't fly within the USA on a commercial flight unless it was an emergency.
