This is part of the funding string: FUND | DEPT | PROJECT | PROGRAM | ACCOUNT CODE

The department ID, also known as UDDS (unit/div/dept/sub-dept), is a seven character code.  It breaks down as follows:

• The first character is alpha-numeric and identifies the campus. 
  A = UW-Madison.  This first character is not always required and is sometimes dropped as UW-Madison is assumed.
  
  
• The next two characters are numeric and identify the division. 
  48 = Letters & Science. 
  
  Other divisions you might work with are:
  07 = CALS
  12 = Business School
  34 = Office of the Vice Chancellor for Research and Graduate Education (VCRGE)
  
  All UW-Madison division codes can be found here.
  
  
• The next two characters are numeric and identify the department. 
  02 = L&S Administration
  
  
• The final two characters are numeric and identify the sub-department. 
  Typically 00 will be used with a project and to identify the department in general on fund 101.  The L&S Budget office may use sub-departments to identify different aspects of your 101 and 131 budgets.  For more information about sub-department usage in 101 and 131 funding, please see the Sub-Department document. 

Pro-tip: the department ID refers to the 6-digit code not including campus; UDDS refers to the full 7-character string.
