Why SIC Code Appending Matters

  • Industry targeting: Segment businesses by core activity using standardized classification.
  • Regulatory alignment: SIC codes are used by regulatory and oversight bodies for reporting and analysis.
  • Data integrity: Consistent classification improves analytics, modeling, and downstream decision-making.

Official & Extended SIC Codes

SICCODE.com applies both official and extended SIC structures to balance regulatory alignment and practical segmentation:

  • Official SIC (2-, 3-, 4-digit): Government-recognized industry definitions used for reporting and compliance.
  • Extended SIC (6-digit): Enhanced granularity for marketing, analytics, and niche market identification.

How the SIC Appending Process Works

1. Secure data submission

Your business file is reviewed for structure, completeness, and matching readiness.

2. Normalization & preparation

Records are standardized to improve match accuracy and reduce ambiguity.

3. SIC code matching

Businesses are classified using official and extended SIC logic with confidence scoring.

4. Quality review

Results are reviewed for consistency and alignment with the approved scope.

Example Use Case

A manufacturing supplier submits an internal customer file for SIC enrichment. After classification, clusters emerge showing strong concentration in specific wholesale and industrial sub-sectors. Using these insights, the company refines its outreach and expands into adjacent industries with similar operational profiles.
