Auto number column in SharePoint list

Question

In a SharePoint list I want an auto number column that as I add to the list gets incremented. How best can I go about this?

Answer 1

If you want to control the formatting of the unique identifier you can create your own in SharePoint. MSDN also has a visual How-To. This basically means that you're creating a custom column.

WSS defines the Counter field type (which is what the ID column above is using). I've never had the need to re-use this or extend it, but it should be possible.

A solution might exist without creating a custom . For example: if you wanted unique IDs like CUST1, CUST2, ... it might be possible to create a Calculated column and use the value of the ID column in you formula (="CUST" & [ID]). I haven't tried this, but this should work :)
