Our Industry Classification Codes
Many classification code systems are in use. These pages list the FSC/PSC, NAICS, NIGP, ODOT, SIC, and UNSPSC codes that seem to best describe our services. On each page, the codes are listed numerically.
The codes that generally fit our services are shown on a white background. Of these, the codes that best fit our services are shown in bold.
Codes listed on a gray background should not be used to describe our services. The gray background indicates the beginning of a major or minor grouping, or a code which is too general to be useful, or a code which should not be used because a better choice exists.
