Microsoft Commerce Server, version 2.0

Q. Are Order IDs and Shopper IDs guaranteed to be unique across multiple

   stores?

A. Order IDs and Shopper IDs are both guaranteed to be unique across

   multiple stores. The Order ID is a pure globally unique identifier
   (GUID). The Shopper ID is a GUID with more randomness added by the
   Commerce Server system. GUIDs are 128-bit integers generated by an
   algorithm that takes into account parameters like the date, time,
   machine address, and other factors.
