Can you get married without a Social Security number?
In order to get married in the United States, a couple must first obtain a marriage license from the state in which they plan to tie the knot. A few states do request that an applicant show proof of a Social Security number (SSN). However, this does not mean that someone without an SSN cannot get a marriage license.
Do you need a Social Security number to get an ID?
All applicants for a driver license and/or identification (DL/ID) card must submit his/her social security number to DMV. The name and birth date you provide on your DL/ID card application must match the name and birth date the SSA has for you in its database.
Can I refuse to give my SSN?
Yes, you can refuse unless you're legally required to provide your Social Security number (SSN). However, there's also no law preventing businesses from asking for it or refusing you service if you don't provide it.
