While I generally agree with the above post, I was asked to complete the form in question when I purchased 3 $1,000 money orders in Boston last month. The form asked for quite a bit of personal information, drivers licence, social security number etc. When I objected, the Post Office clerk told me that all I needed to do was to purchase no more than 2 $1,000 money orders at a time, simple enough. So, even with a line of people behind me, I was asked to fill out one of these forms.
