My questions are the same:
what is a serial number to you? is it a random number? can it be '0000' plust the customer number?(0001,0002, etc). Why did your example have a wide range of values?
is the number unique? does it need to follow a business pattern(ie SN0000YYYY0001 so it makes "at-a-glance' sense to some people?
