I wonder what would happen if you provided a signed statement saying, "I have entered 000-00-0000 on my passport application because, while I have a SSN, I do not have to give it to you per the Privacy Act of 1974, and I am retaining that right."
...other than that if you were going to take that approach, you should probably allow at least 6 months before travel.
In any case, agpt, good luck.
