Complete Guide to SSIC Codes in Singapore: How to Choose, Search, and Update Your Business Classification

When incorporating a business in Singapore, one of the most critical steps required by the Accounting and Corporate Regulatory Authority (ACRA) is choosing your SSIC code. Declaring the correct classification is an essential requirement in the company incorporation process, as it legally defines your commercial activities in the eyes of the government.

To help you navigate this step seamlessly, this comprehensive guide covers everything you need to know about Singapore's classification framework, along with practical tips on using the official SSIC search tool and directory guides.

What is an SSIC Code in Singapore?

Definition of Singapore Standard Industrial Classification

SSIC stands for Singapore Standard Industrial Classification. Developed and maintained by the Department of Statistics (DOS), the SSIC is the official national standard used to classify economic activities undertaken by commercial entities in Singapore.

The system is modelled after the United Nations' International Standard Industrial Classification of All Economic Activities (ISIC) and is regularly updated to reflect emerging industries, digital business models, and economic trends.

Why Does ACRA Require SSIC Codes During Incorporation?

When registering a business on ACRA's Bizfile portal, every commercial entity must declare its business activities using these standardised codes. ACRA uses SSIC codes to:

• Track Economic Activity: Categorise and analyse national economic data across various commercial sectors.
• Determine Regulatory Scope: Identify whether your business activities require additional approvals, permits, or specialised business licenses in Singapore.
• Taxation & Incentives: Help government bodies (such as IRAS) evaluate tax classifications and eligibility for sector-specific grants.

Structure of an SSIC Code

SSIC codes consist of 5 digits that categorise economic activity from a broad sector down to a highly specific business activity.

How the 5-Digit Classification Works

The code hierarchy is structured as follows:

• Section (1st digit/letter): The broadest economic sector (e.g., Section J - Information and Communications).
• Division (2 digits): The major group within the section (e.g., Division 62 - Computer programming, consultancy and related activities).
• Group (3 digits): Specific industry branch.
• Class (4 digits): Sub-industry division.
• Item (5 digits): The exact SSIC code assigned to your specific business activity.

Example Breakdown:

For a software development agency, the 5-digit SSIC code is 62011:

• 62: Computer programming, consultancy and related activities
• 620: Computer programming and consultancy activities
• 6201: Development of software and computer programming
• 62011: Development of software and applications (except games and cybersecurity)

Why Choosing the Right SSIC Code Matters

Selecting an accurate SSIC code is far more than a simple administrative formality, as it directly impacts your operational setup and legal standing in Singapore.

1. Regulatory & Licensing Compliance

Certain SSIC codes automatically trigger mandatory licensing requirements from regulatory authorities before you can commence business operations. For example:

• Financial Services / Fintech: Requires licenses or exemptions from the Monetary Authority of Singapore (MAS).
• Real Estate / Travel Agencies: Requires permits from the Council for Estate Agencies (CEA) or the Singapore Tourism Board (STB).
• Food & Beverage: Requires approval from the Singapore Food Agency (SFA).

Declaring an incorrect SSIC code could lead to compliance delays or legal issues regarding unlicensed operations.

2. Corporate Bank Account Opening

Financial institutions and fintech platforms review your declared SSIC code during Know Your Customer (KYC) and Anti-Money Laundering (AML) assessments. If your declared code does not align with your actual business model or transactional activity, your application for a business bank account may experience significant delays or rejection.

3. Tax Exemptions & Government Grants

The Inland Revenue Authority of Singapore (IRAS) and Enterprise Singapore offer various tax rebates and grants targeted at specific sectors. Having the appropriate SSIC code ensures your company qualifies for applicable tax schemes and corporate tax rate exemptions.

Primary vs. Secondary SSIC Codes

How Many SSIC Codes Can a Company Have?

Every registered Singapore business can select up to two SSIC codes:

1. Primary SSIC Code: Represents your main business activity (the primary source of revenue).
2. Secondary SSIC Code (Optional): Represents a secondary or complementary business activity.

What If Your Business Has Multiple Revenue Streams?

If your enterprise engages in more than two distinct business activities, you should select the two SSIC codes that account for the largest proportion of your revenue. You can also provide a detailed explanation of your full operational scope in the custom "User-Entered Description" field on Bizfile during incorporation.
