Document IDs are only guaranteed unique within a single site collection. SharePoint tries to ensure uniqueness by putting a random prefix in front of each Docuemnt ID, and setting that at the Site Collection level. However you can easily rationalize these, and make the Document IDs a bit easier to read. The script below assigns a prefix, and sets up SharePoint to reissue Document IDs. Note the actual regeneration of Document IDs will wait until the Document ID Assignment Timer Job runs. This job can take a long time to run, depending on the number of items in your Site Collections.<\/p>\n
