What is SSIC?
The Singapore Standard Industrial Classification (SSIC) is a coding system used to classify business activities in Singapore. It is based on the United Nations International Standard Industrial Classification (ISIC) Rev. 4.
Every business registered in Singapore must declare at least one SSIC code that describes its primary business activity. This code is used by ACRA and other government agencies for statistical and regulatory purposes. When registering a company in Singapore, selecting the right SSIC code is one of the first decisions you will make.
Required for all businesses. Describes your main business activity.
Optional. Use if your business has significant secondary activities.
SSIC Code Structure
SSIC codes follow a hierarchical structure with 4 levels of classification. The code you select applies regardless of your business entity type — sole proprietorships, partnerships and companies all use the same SSIC system.
Broadest category, e.g., "C" for Manufacturing
Major industry group, e.g., "62" for Computer Programming
Industry group, e.g., "620" for Computer Programming Activities
Specific activity, e.g., "62011" for Software Development. Use this level for ACRA registration.
