Singapore KYB: verify a company from its UEN

For a fintech, a payment provider or a marketplace onboarding a Singapore business, the first KYB step is simple: is this a real, live, registered entity, and is it the one the applicant says it is?

The check in one call

The applicant enters a UEN. You call GET /companies/search?country=SG&company_number=... and compare what comes back with what they told you.

Check	Field	Reads as
The entity exists	company_number, company_name	A match means ACRA's data holds the entity; no match means stop and ask.
Name matches the application	company_name, previous_names	Compare names, allowing for a recent change.
It is alive	status, status_code	Active, or a state that needs a decision: liquidation, judicial management, receivership, strike-off, merged, deregistered.
Type is what you accept	legal_form	Private company, public company, LLP, foreign company branch.
Address is plausible	address, postal_code	The registered address, six-digit postal code.
Activity fits the product	activity_code	The SSIC 2020 code for the declared business.
Filing hygiene	annual return and accounts due dates	A long-overdue date is a soft signal.

Keeping it current

KYB is not a one-off. Add the entity to POST /monitor and a webhook arrives when its status, name, legal form or registered address changes, for example a move into liquidation or a strike-off. The register is read monthly, so a change is dated by the read that first shows it, none before the first load in October 2026.

What this check does not cover

• Sole proprietorships, partnerships and limited partnerships. Never served. If your applicant is one, the lookup returns nothing: collect other evidence.
• Directors, shareholders and beneficial owners. There are no officers in the record, so ownership and UBO checks come from elsewhere (for example the company's own register of controllers and documents from the applicant).
• GST. No GST number, no GST status.
• Sanctions and PEP. Separate: sanctions screening is available through the API (beta); PEP screening is beta and Spain only.
• Share capital. Not in the record.

Where it sits in a KYB flow

Treat the register match as the identity step: it proves the entity exists and reads its status. Ownership, control and screening are separate steps, and the regulatory expectations for them in Singapore (MAS notices on anti-money laundering for financial institutions, for instance) are yours to apply; the API supplies the data for the first step and does not make the compliance decision. For the generic flow see KYB onboarding.
