Frequently asked questions

Why was my SSIC code automatically changed from 42100 to 42101?

Singapore's national industrial classification was updated from SSIC 2020 to SSIC 2025, effective 9 May 2026. ACRA's BizFile+ system automatically mapped every existing entity to its closest SSIC 2025 equivalent using the official SingStat correspondence table. The code SSIC 42100 (Civil engineering general contractors) was reclassified to SSIC 42101 (General contractors (non-building construction)) under that mapping.

Do I need to take any action?

Usually no. If your business activity is unchanged, the new code accurately reflects it under SSIC 2025 and no manual update is needed. You should only update if (a) the auto-mapped code doesn't match what you actually do, (b) your activity has changed independently, or (c) you claim a sector-specific licence or grant tied to the old code.

How many Singapore companies were affected by this specific recode?

Based on the change log we've maintained since the 9 May 2026 cutover, 163 companies have been reclassified from SSIC 42100 to SSIC 42101. Of those, 163 had it as their primary SSIC code and 0 as a secondary code.

What's the difference between SSIC 42100 and SSIC 42101?

SSIC 42100 was titled "Civil engineering general contractors". Under SSIC 2025, the equivalent activity sits at SSIC 42101 ("General contractors (non-building construction)"). The two cover the same underlying activity per SingStat's official correspondence table; the SSIC 2025 title and number reflect the updated classification.
