[QUOTE="oldster, post: 149980, member: 8104"] The 1Z is an industry standard. I simply designates the type and length of the information that follows. In tracking numbers, (1Z-666666-01-12345678), the 6 digits after the 1Z are the shipper number, the 01 is the service level of the package, in this example 1DA, and the last 8 digits are the unique tracking for the package. Several years ago, the 8 digit tracking number always increased by 9 for each package from the same shipper. It is now a randomized number, but there is an algorythym built in that serves as a validation for key-entering. [/QUOTE]
