If Broadvox has really shipped, UPS doesn't know about it.
"UPS could not locate the shipment details for the tracking number you entered.
Please make sure the tracking number you entered is valid and try again."
The number may just be an electronic reference number which indicates an upcoming shipment.
For my case Lingo generated such a number days before shipping the item.
It should work for tracking once UPS has received the physical item and scans it into their system.
if you call 1800 PICKUPS they will tell you that the number is indeed valid but they have no information on it at this time. You are then told to contact the shipper. (when you get to the live operator)
