It looks cool.Hi All,
Can anyone shed any light on why all UPS tracking numbers begin with 1Z? I've read the article at:
UPS Pressroom: Fact Sheet
But it doesn't explain why "1Z". You could just as easily use "2Y", or any other number/letter combination. Why did the people, at the time, decide on 1Z.
Anyone?
Thanks in advance,
