1. What is an industry business code?
An industry business code is a sequence of numbers encoded to represent a specific business line. Organizations and individuals, when preparing business registration documents, must use this industry business code table for registration. The 4-digit (level 4) industry code is the code used for business registration.
The Vietnam Standard Industrial Classification (VSIC) system, issued under Decision 36/2025/QD-TTg, has a hierarchical structure with 5 levels, from general to specific:
| Level | Name | Code | Number |
|---|---|---|---|
| Level 1 | Level 1 Economic Sector | 1 letter (from A to V) | 22 sectors |
| Level 2 | Level 2 Economic Sector | 2 digits (based on Level 1) | 87 sectors |
| Level 3 | Level 3 Economic Sector | 3 digits (based on Level 2) | 259 sectors |
| Level 4 | Level 4 Economic Sector | 4 digits (based on Level 3) | 495 sectors |
| Level 5 | Level 5 Economic Sector | 5 digits (based on Level 4) | 743 sectors |
Example of industry code structure: Taking the food production industry as an example:
- Level 1: C (Processing and Manufacturing Industry)
- Level 2: 10 (Food Processing and Production)
- Level 3: 107 (Manufacture of other food products)
- Level 4: 1075 (Manufacture of prepared meals and dishes)
