Frequently asked questions
Why was my SSIC code automatically changed from 91010 to 91100?
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 91010 (Libraries and archives activities) was reclassified to SSIC 91100 (Libraries and archives activities) 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, 21 companies have been reclassified from SSIC 91010 to SSIC 91100. Of those, 9 had it as their primary SSIC code and 12 as a secondary code.
What's the difference between SSIC 91010 and SSIC 91100?
Both codes describe Libraries and archives activities. The change is a renumbering under SSIC 2025 with no scope change — the activity definition is the same.
Where can I look up other SSIC 2020 to 2025 mappings?
