1. What is a business line code?

Business line codes are a series of numbers encoded to represent a specific business line. Organizations and individuals, when preparing business registration documents, must use this business line code table for registration. Level 4 industry codes (4 digits) are used for business registration.

The Vietnam Standard Industrial Classification (VSIC), promulgated under Decision 36/2025/QD-TTg, has a hierarchical structure with 5 levels, from general to specific:

Level	Name	Code	Quantity
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
