SUMMARY
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.

Additional query words: IDs
