1. What is a Business Industry Code?

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 level 4 industry code (4 digits) 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 Code Quantity
Level 1 Economic Activity Level 1 1 letter (from A to V) 22 industries
Level 2 Economic Activity Level 2 2 digits (according to Level 1) 87 industries
Level 3 Economic Activity Level 3 3 digits (according to Level 2) 259 industries
Level 4 Economic Activity Level 4 4 digits (according to Level 3) 495 industries
Level 5 Economic Activity Level 5 5 digits (according to Level 4) 743 industries

  • Level 1: C (Manufacturing)
  • Level 2: 10 (Manufacture of food products)
  • Level 3: 107 (Manufacture of other food products)
