1. What is a Business Industry Code?
Business industry code is a sequence of encoded numbers representing a specific business line. Organizations and individuals, when preparing business registration documents, must use this business industry code table for registration. The 4-digit (level 4) industry code is used for business registration.
The Vietnam Standard Industrial Classification (VSIC) system, issued under Decision 36/2025/QĐ-TTg, has a hierarchical structure comprising 5 levels, from general to specific:
| Level | Name | Encoding | Quantity |
|---|---|---|---|
| Level 1 | Economic sector level 1 | 1 letter (from A to V) | 22 sectors |
| Level 2 | Economic sector level 2 | 2 digits (based on level 1) | 87 sectors |
| Level 3 | Economic sector level 3 | 3 digits (based on level 2) | 259 sectors |
| Level 4 | Economic sector level 4 | 4 digits (based on level 3) | 495 sectors |
| Level 5 | Economic sector level 5 | 5 digits (based on level 4) | 743 sectors |
