Internal Names of SharePoint User Profile Fields

SharePoint user profile contains information about the user such as name, title, phone number, email address, etc. It has two types, namely WSS Profile and MOSS Profile. WSS Profile can be accessed from Welcome User >> My Settings page (_layouts/userdisp.aspx?.......) while MOSS Profile can be accessed from My Site (../Person.aspx?....) and it is created when users are imported into the system from AD or LDAP.

Basically, there are two MOSS Timer jobs that control the replication of the user profiles per web application. These are Profile Synchronization and Quick Profile Synchronization. The difference between the two is Profile Synchronization updates the WSS profile whereas Quick Profile Synchronization updates the MOSS profiles. Both of these jobs can be found in Central Administration -> Operations -> Timer Job definitions. 

If you want to access the user profile columns / fields in code, you need to know its equivalent internal names. Actually, the internal names of the columns are different depending on the types of user profile.

So for your reference, I have listed below the user profile fields and its corresponding internal names.
