The Document ID Service is enabled and creates a unique ID for each document.
To configure the ID Service to be more user friendly:

Please note, we recommend changing this as soon as you configure the new SharePoint site and advise against changing at a later date. If you are unsure or would like to change the Document ID settings, please contact your systems administrator.
