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