UEN lookup
Search 2.09 million Singapore companies from the ACRA registry by UEN or name. Entity status, industry, and registration date in seconds. Free, no signup.
What a UEN is and how to read the format
The Unique Entity Number is the single ID every registered entity in Singapore uses with government agencies. The format tells you what kind of entity you are looking at. Businesses registered with ACRA before 2009 carry 9 characters (8 digits plus a check letter, e.g. 53333333A). Local companies carry 10 characters where the first 4 digits are the year of incorporation (e.g. 201912345K means a company incorporated in 2019). Other entities such as LLPs, societies, and trade unions get a 10-character UEN starting with T, S, or R followed by the year, an entity-type code, and a serial number (e.g. T08LL0001B).
What ACRA data tells you about a prospect
Before a first call, the registry answers four useful questions. Is the company real and active? The entity status shows whether it is Live, Struck Off, or winding up. What does it actually do? The SSIC code is the company's self-declared principal activity, which is often more accurate than its website copy. How mature is it? The registration date separates a 2-month-old startup from a 20-year incumbent, which changes your pitch. And what legal form is it? A sole proprietorship buys very differently from a private limited company with a procurement process.
UEN vs GST registration number
They are usually the same thing, which causes confusion. For most local companies the GST registration number is simply the UEN, so an invoice showing "GST Reg No 201912345K" is quoting the UEN. The exceptions are foreign companies and some divisional registrations, which get a separate GST number in the format MX-NNNNNNN-N or similar issued by IRAS. Also note that holding a UEN does not mean a company is GST-registered: registration is only compulsory above S$1 million in annual taxable turnover, so many small companies have a UEN but no GST number at all.
How sales teams use registry data for ICP filtering
One lookup verifies a prospect; the registry as a dataset builds a territory. Teams selling in Singapore filter the 2.09 million entities down to a working list: Live status only (dead entities waste dials), the SSIC codes that match their best customers (say 62012 for software development or 46900 for general wholesale), incorporation date for company maturity, and entity type to exclude sole proprietors when the product needs a corporate buyer. That turns a vague "SMEs in Singapore" ICP into a concrete, finite list you can actually work through, and it is built entirely on public data.
From one lookup to a full prospect list
HuntSales puts the whole ACRA registry behind filters: SSIC, status, age, and entity type, plus contacts and outreach in one place.

What is a UEN number in Singapore?
A UEN (Unique Entity Number) is the standard identification number issued to every business entity registered in Singapore, including companies, sole proprietorships, partnerships, and LLPs. It is used in all dealings with government agencies, from CorpPass and IRAS filings to CPF and grant applications.
How do I find a company's UEN for free?
Type the company name into the search box above. The tool searches the ACRA public registry of about 2.09 million entities and returns the UEN, entity status, industry classification, and registration date at no cost. ACRA's own BizFile portal also offers a free basic search.
Is this UEN lookup using official ACRA data?
Yes. The results come from ACRA's open data published on data.gov.sg, which mirrors the official register of entities. For certified extracts, officer details, or filing histories, you would purchase a Business Profile from ACRA BizFile.
What does entity status like Live or Struck Off mean?
Live means the entity is currently registered and active on the register. Struck Off means ACRA has removed it, usually because it ceased business or failed to meet filing obligations. Other statuses include In Liquidation, Dissolved, and Cancelled. For prospecting, you generally only want Live entities.
Can I look up who owns or directs a company here?
No. Shareholder and director details are not part of ACRA's free open dataset. They are available in the paid Business Profile from ACRA BizFile. This tool shows the public-registry fields only: name, UEN, status, industry, and registration date.
How many companies can I search?
The tool is free with a fair-use limit of 20 lookups per hour. If you need bulk access to the full registry with filters, contact data, and exports, the HuntSales platform includes every ACRA-registered company on the free plan.
