Are Sharepoint List GUIDs unique for whole life of the site? RRS feed

  • Question

  • Hello,

    I need to have auditability for my sharepoint list.

    We are monitoring Unique IDs of items to ensure no item has been deleted.

    How to protect the amdin to delete the list and recreate with different data? I d like to use List GUID but not sure it is possible that Sp2007/or administrator can ever assign the same ID to a new list as was once used for a deleted list. do you know?

  • Yes, you can be rest assured that the list GUIDS are unique

    GUID stands for Globally Unique IDentifier. It is a string of numbers and/or letters. e.g. {b91c9121-0a17-4b26-a09d-d5980eb532db}
     
    A GUID represents a Unique identifier - means you cannot generate the same GUID more than once. A GUID has a very low (...practically impossible) probability of being duplicated.

    1. A Site
    2. A Web
    3. A List
    4. A Content Type
    5. Etc.

  • A GUID, by its nature is unique and persistent.  They're persistent across the duration of an item/list/sites existence but there are some gaps, such as if you copy an item into another site, that copy will generate another GUID rather than having the same unique identifier.
