Frequently asked questions

About this specific SSIC code and the Digital, IT & Telecom sector

What IMDA telecom licences are required?

Telecommunications and broadcasting services require licences from the Infocomm Media Development Authority (IMDA), including Facilities-Based Operator or Services-Based Operator licences.

Are there cybersecurity compliance requirements?

Owners of Critical Information Infrastructure must comply with the Cybersecurity Act. All organisations are encouraged to follow the CSA Cybersecurity Code of Practice.

What is the data breach notification timeline?

Under the PDPA, organisations must notify the PDPC and affected individuals of a data breach as soon as practicable, within 30 days of assessment, if the breach causes significant harm.

Do I need to register under the PDPA?

Organisations collecting, using, or disclosing personal data in Singapore must comply with the Personal Data Protection Act (PDPA). Registration with the PDPC is not universal but obligations apply to all.

What is SSIC and why does it matter?

The Singapore Standard Industrial Classification (SSIC) is the national system for categorising business activities. It is mandatory at ACRA registration and is used by IRAS, MOM, and other government agencies for tax, licensing, statistical, and policy purposes.

Do I need to register with this SSIC code?

Every business entity registered with ACRA must select at least one SSIC code that best describes its principal economic activity. You can declare up to two codes — one primary and one secondary — via BizFile+.

What international standard does SSIC map to?

SSIC 2025 is aligned with the UN International Standard Industrial Classification (ISIC) Rev. 5. Each SSIC code maps to one or more ISIC Rev. 5 classes, making Singapore business data internationally comparable.

Can I hold more than one SSIC code at the same time?

Yes. ACRA allows one primary SSIC code and one secondary SSIC code per registered entity. If your business spans multiple distinct activities, choose the code that generates the highest share of revenue as primary.

How do I change my registered SSIC code?

You can update your SSIC code through BizFile+ by filing a "Change in Business Activity" transaction. Changes take effect upon ACRA approval. IRAS and other agencies should also be notified if the change affects tax classification.
