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