From Skyrim Wiki
The ID field used in this wiki refers to the item ID number used internally by the The Elder Scrolls V: Skyrim. All assets within the game have a unique ID number, and sometimes more than one, if the asset in question has different forms.
- Asset IDs in the original game all begin with 00. For example, the book The Holds of Skyrim has an ID of 000ed030.
- Asset IDs in the DLC all begin with 02, 03 or 04, depending on how many of the modules are loaded and in which order they were installed. For example, the weapon "Dawnguard War Axe" might have an ID of 0200d098, if the Dawnguard DLC was the first to be installed after the original game. For example, if you loaded the DLC in the order they appeared for sale, IDs would be as follows:
