Shovels includes industry classification data for contractors, though this data has important limitations to understand.

Available Classification Fields

FieldDescription
NAICSNorth American Industry Classification System codes
SICStandard Industrial Classification codes
Primary_industryGeneral industry classification

Data Sources

Business industry classifications come from self-reported data, typically through:
  • Business registration
  • Insurance-related transactions

Important Limitations

Self-Reported Nature

Classifications are self-reported by businesses, not verified by Shovels.

Broad Categories

Classifications are quite broad and may not precisely reflect a contractor’s specialization.

Multiple Classifications

Companies in higher-risk occupations often use multiple industry identifiers to reduce their workers’ compensation insurance liability.

No Central Authority

There is no central authority governing these categories.
The Primary_industry field should be taken with a grain of salt due to these limitations.

NAICS vs SIC

SystemDescription
NAICSMore modern and specific classification system
SICOlder system, but more widely adopted
Both are included in our data because NAICS isn’t as widely adopted as SIC codes.

Better Alternatives

For understanding what a contractor actually does, consider:
  • Permit descriptions - What work they’ve actually permitted
  • Tags - Shovels-assigned categories based on permit data
  • Permit history - Patterns of work they’ve completed
