Codes for Principal Business Activity
This list of principal business activities and their associated codes is designed to classify an enterprise by the type of activity in which it is engaged. These principal business activity codes are based on the North American Industry Classification System.

Using the list of activities and codes below, determine from which activity the company derives the largest percentage of its "total receipts." Total receipts is defined as the sum of gross receipts or sales plus all other income. If the company purchases raw materials and supplies them to a subcontractor to produce the finished product, but retains title to the product, the company is considered a manufacturer and must use one of the manufacturing codes (311110-339900).

Once the principal business activity is determined, enter the six digit code selected on your application.
