Change a Singapore SSIC Code: Business Activity & Licence Impact

Identify what has changed in the business

Start with the commercial change, then decide which record needs attention. A different marketing slogan may describe the same service; selling a new product, manufacturing something previously bought for resale, or operating from a new type of premises can require a much wider review. Write a before-and-after description that a person outside the company can understand.

Record four facts: what customers receive, what the company itself does, where the work occurs, and when the change actually takes effect. Attach a representative contract, order description or management analysis where useful. These are recommended working papers for an accurate decision, not a universal list of documents to upload to ACRA.

An SSIC update concerns the activities of the existing registered entity. If the commercial proposal instead places the activity in a new company, the underlying company registration process in Singapore becomes a separate decision; do not use an activity edit to represent a new contracting party.

Keep a code correction and an operational pivot distinct. A historical miscoding needs a supported correction, whereas an actual pivot needs a documented change date. When those dates differ, explain both internally rather than selecting today merely because it is the filing day.

Match the revised operation to an SSIC description

Select the description that fits the work performed, including its exclusions. ACRA’s SSIC selection guidance uses five-digit codes for primary and, where applicable, secondary activities. A broad commercial label such as technology, trading or food does not explain whether the company develops, resells, prepares, distributes or merely introduces customers.

The Department of Statistics defines the principal activity by the largest contribution to value added. Where that information is unavailable, it permits alternatives including output, sales and employment measures. Its SSIC 2025 definitions and classification references also distinguish a secondary activity supplied to third parties from an ancillary function supporting the business itself.

Prepare a short comparison of the current and proposed descriptions against the same operating facts. Use value added before convenient labels as the starting point for the primary activity; explain any alternative measure used. An internal bookkeeping team, for example, should not be confused with a separate accounting service sold to clients.

SingStat publishes correspondence tables between classification editions. If an old code and a current description differ, compare their scopes before concluding that the business has changed. Select from the options available in Bizfile at filing, rather than copying a number from an old certificate or a competitor’s profile.

When two descriptions still appear plausible, selecting an SSIC code for the actual activity requires a precise account of the product, customer and delivery model. Save the reason for choosing one description over the other; that explanation is more useful for later queries than a keyword search result.

The next task has two separate outputs: a corrected company record and a supported operating decision. The licence assessment can begin while the filing information is prepared, but its outcome must remain visible after the ACRA task is closed.

File the activity update in Bizfile

An authorised officer or corporate service provider can make the update. ACRA’s entity-information procedure , checked on September 8, 2026, lists this transaction as free (S$0) with immediate processing. That is the record update, not a timetable for obtaining permission to operate. Professional assistance and separate licensing work fall outside it.

1. Log in to Bizfile as a Business User through Corppass. Select the correct entity and open its entity details.
2. Open Business activities in Entity Information and select Edit.
3. Search for or enter the SSIC code, then select the activity description; add a secondary activity if applicable.
4. Enter the effective change date and review and confirm the information.
5. Complete the submission and retain the confirmation message and Bizfile inbox notification.

For additional activities beyond the primary and secondary entries, ACRA directs filers to General Lodgement (Others), including each relevant SSIC code. Foreign companies have 30 days to report changes, unlike the local-company deadline. Confirm the registered entity type before applying that exception.

Before submission, have a second person compare the chosen description and date with the working papers. After submission, reopen the activity record and inspect what is actually displayed. A screenshot taken before confirmation proves only what was entered, so label draft screens separately from the retained final record.

Keep the internal approval question separate from the portal fields. ACRA treats constitution alterations as a distinct filing involving a special resolution. If the pivot changes a restriction in the constitution, obtain the required corporate advice and approval for that alteration; a business-activity edit does not amend the constitution itself.

Choose the licence action from the operational change

Changing the SSIC record does not enlarge the scope of an existing licence. Compare the actual operation with the permission held, including the licence holder, activity and premises. A useful review records which fact has changed and which authority must decide whether notification, amendment or a fresh application is appropriate.

Food retail provides a concrete example. The Singapore Food Agency (SFA) requires a fresh application when changed operations need a different licence type; its licences cannot be converted from one type to another. A change of licensee or business Unique Entity Number (UEN) also requires a fresh application because licences are not transferable. SFA’s food-retail licensing requirements require the relevant licence before operating.

Use the following matrix as a working decision aid. The ACRA and SFA rules above supply the boundaries; the evidence column is a recommended way to document how those boundaries apply to your company.

A licence check should end with a reasoned outcome, not simply “no issue found”. If permission is required, record the exact activity covered and any outstanding conditions. If the activity falls outside a licensing requirement, retain the authority’s relevant guidance and the facts supporting that assessment. An unresolved classification question belongs with the relevant regulator before the controlled operation starts.

Close discrepancies across company and operating records

Assign one person to reconcile the revised description across the company file and the documents used operationally. Ask the account provider, insurer or contracting counterparty whether its own information or terms need updating. This is a practical follow-up recommendation, not a claim that every third party imposes the same notification deadline.

There is a specific employment consequence where the company uses Employment Pass assessment under the Complementarity Assessment Framework (COMPASS). The Ministry of Manpower (MOM) groups employers by primary activity. After an ACRA activity update, MOM says its records may take up to two weeks to refresh; check the sector shown in Workforce Insights. MOM’s sector-classification guidance warns that inaccurate or missing SSIC information can cause work-pass delays or rejection.

If the wrong description was filed, establish the correct operating facts before making another submission. If the portal shows no confirmation, inspect the inbox and current entity record before repeating the transaction; preserve the error details for ACRA support. If the uncertainty concerns licence scope, a second ACRA edit cannot resolve that regulatory question.

Keep an open-item list for anything still awaiting a third-party response. Give each item an owner, the question sent and the document needed to close it. This avoids treating a successful filing as permission to issue a regulated offer, start production or open premises before the relevant approval is established.

Release the revised activity only when its evidence is complete

Proceed with the SSIC update once the proposed description and change date can be supported. Keep the launch conditional on the separate licence conclusion: existing permission demonstrably covers the revised operation, required new permission is effective, or a documented assessment establishes why that activity does not require it.

Escalate before operating if the licence holder differs from the contracting company, the activity falls outside the stated licence type, or the business description remains disputed. Close the change only when the company record, operating facts and relevant permission tell the same story.
