Identifying Field Mappings in the User Profile

Now, generally speaking, the field labels within the Edit Profile screen for User Profiles in SharePoint 2010 should map to their display name (see below)

Or, when in the Edit screen for the property, you can see what the Display Name is, as well as the internal name above the highlighted section as Name.

However, there may be instances where this is being overridden somewhere, maybe in the master page through some JavaScript or something. Or, perhaps something else altogether. If you look at the source of the Edit Profile page, and in my example, I will be looking at the Company field, which is the Display Name for the Department default field in my case

A quick way to find this out, when viewing the source, is to search fro that field. In my instance, Company

You will notice on the end of the highlighted field ID, _ProfileEditorValueDepartment, where Department is the internal field name, and not the display field name, so you instantly have the Display to Internal mapping you need, without going through each property in the profile property management screen in the service application.
