Not necessarily. I was in PFS for quite some time before tracking came on line.
At UPS, click the "Tracking" tab at the top, then over on the left side is "Track by Reference"
You can use your billing number (just the ten digits, no dashes or parentheses or spaces), or your "W" order number from Apple minus the last two digits. If you use your billing number and there are other packages out there using it, UPS will ask for more information like your zip code.
UPS My Choice is way better than tracking by reference, but not everybody can use that.
