Classification Codes and Statistical Codes Manual
Classification Codes and Statistical Codes Manual is a historical record of classification and statistical codes. The online manual provides the code number and corresponding phraseology (filed code description) for each classification and statistical code, including state special codes and independent bureau codes. Use the manual to find out if a code is a state special, a federal classification, a statistical code, or has been discontinued. Most entries indicate the date a code became effective or was discontinued. You can also find out if a discontinued code has been reassigned or retained as a state special. In addition, the manual indicates the schedule (or general industry division) and group numbers.
