1. What is a business industry code?
Business industry codes are a series 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. Level 4 industry codes (with 4 digits) are the codes used for business registration.
The Vietnam Standard Industrial Classification (VSIC) system, promulgated under Decision 36/2025/QD-TTg, has a hierarchical structure with 5 levels, from general to specific:
