SIC 5 vs SIC 7 - Key Differences Between South Africa's Classification Systems
Detailed comparison of SIC Edition 5 and SIC Edition 7 in South Africa. Structure changes, new sections, code mapping, and migration guide.
South Africa has used two major editions of the Standard Industrial Classification system: Edition 5 (published 1993) and Edition 7 (published 2012). Understanding the differences is essential for anyone working with historical data, converting old codes, or interpreting government statistics.
Structural Changes
| Feature | SIC Edition 5 | SIC Edition 7 |
|---|---|---|
| Based on | UN ISIC Revision 3 | UN ISIC Revision 4 |
| Top-level coding | Numbers (0-9) | Letters (A-U) |
| Top-level name | Major Divisions | Sections |
| Number of sections | 10 | 21 |
| Number of divisions | 50 | 88 |
| Number of subclasses | 466 | 521 |
| Code digits | 5 digits (numeric) | 5 digits (numeric) |
| Year introduced | 1993 | 2012/2013 |
New Sections in SIC 7
The most significant change was the expansion from 10 to 21 top-level sections. Several new sections were carved out of existing ones to better reflect the modern economy:
| Section J (Information and Communication) - Previously scattered across several SIC 5 categories, ICT and media activities now have their own section, reflecting the digital economy's importance.
| Section L (Real Estate) - Separated from financial services.
| Section M (Professional, Scientific and Technical) - Broken out from business services.
| Section N (Administrative and Support Services) - Similarly separated from business services.
Why the Change Matters
SARS began requiring SIC 7 codes on the ITR14 form from 2013. Statistics South Africa and other government agencies have also transitioned to SIC 7. If you are working with data spanning before and after 2013, you need to use a crosswalk table to ensure comparability.
Our SIC 5 to SIC 7 Crosswalk Table maps every SIC 7 code to its approximate SIC 5 equivalent, with a searchable filter to quickly find specific codes.
