What is a Tracking Number?
Tracking numbers are used by UPS to identify and trace every package as it moves through the UPS system to its destination. UPS automatically assigns a tracking number to your package. Other types of tracking numbers are UPS InfoNotices (US only) and UPS Service Notices (outside of the US).
UPS Tracking Numbers appear in the following formats:
1Z 999 999 99 9999 999 9
9999 9999 9999
T999 9999 999
