Is it possible to generate reference number to load with a new form the moment I click to create new item in SharePoint?

You can do it using Visual studio. You will need to build the list and deploy it as a feature. For the list, create the new form, edit form and display form. You can generate an unique guid when creating a new item each item, which can be used as a reference number. Thanks V V

Hi, You can create a column of type "Calculated" and create a formula based on your requirement (you can use ID column to provide unique reference number to items within the list). Regards.

Well, I guess he was trying to load the new GUID even before a new item is created. The calculated column works after the item has been created and not before. Thanks VV
