company registration no Singapore: How to Find, Verify and Use Your Corporate UEN

If you plan to start or check a Singapore company, the Unique Entity Number (UEN) serves as the official company registration no Singapore businesses use for everything from filing with ACRA to dealing with government agencies. The UEN proves a business is legally registered in Singapore and lets you verify status, ownership, and filing history quickly through ACRA’s BizFile+ and other official services.

Knowing how the UEN fits into different business structures and the basic steps to register or verify a company saves you time and reduces compliance risk. This article walks you through what the UEN means for sole proprietorships, partnerships and private companies, and gives a clear, practical path to registering or checking a company using ACRA’s online systems.

Legal Framework and Business Structures

Singapore bases company formation on clear laws, defined entity types, and specific registration steps enforced by designated agencies. You must pick a legal form that matches your liability tolerance, tax needs, and ownership plans, then meet document and filing requirements with the proper authority.

Types of Entities in Singapore

You can choose among several common forms: Private Limited Company (Pte. Ltd.), Sole Proprietorship, Partnership (general or limited), and Limited Liability Partnership (LLP).

A Private Limited Company offers separate legal personality, limited liability for shareholders, and favorable tax treatment; it requires at least one resident director and a company secretary.

Sole proprietorships and general partnerships expose owners to unlimited personal liability and suit very small, low-risk businesses.

LLPs combine partnership flexibility with limited liability for partners; they require at least two partners and registration with ACRA.

Consider administrative burden, funding needs, and investor expectations: venture capital and institutional investors typically prefer Pte. Ltd. structures.

Mandatory Registration Requirements

You must register any business entity that carries on a trade or business in Singapore, using BizFile+ for filings.

Key documents include: company constitution (for Pte. Ltd.), particulars of directors and shareholders, registered office address, and details of the company secretary.

Minimums: one shareholder, one resident director, and a registered local address; foreign nationals can hold shares but need a local director or use nominee/director services.

You must provide certified ID and proof of address for individuals, and file a Constitution or set of Articles when incorporating.

Registration fees and timelines vary by entity type; a Pte. Ltd. typically completes incorporation within 1–3 working days if documents are in order.

Authorities Involved in Business Registration

The Accounting and Corporate Regulatory Authority (ACRA) is the primary regulator for company registration, incorporation, and business name reservation via BizFile+.

The Inland Revenue Authority of Singapore (IRAS) handles tax registration, corporate tax residency, and GST registration if your taxable turnover exceeds the threshold.

For regulated sectors, you must also obtain licenses from sectoral agencies such as the Monetary Authority of Singapore (financial services), Singapore Food Agency (food), or Ministry of Manpower (work passes).

You will interact with government e-services (BizFile+, myInfo) and may need professional advisers (corporate secretaries, accountants, lawyers) to meet compliance and post‑incorporation filing deadlines.

Step-by-Step Guide to Registering a Company

You will prepare documents, submit an online application through ACRA’s BizFile+, and receive your company registration number and incorporation documents once approved. Follow each stage precisely to avoid delays and meet statutory requirements.

Preparation of Required Documents

Gather key documents first: completed incorporation application, proposed company name approval, signed constitution (formerly Memorandum & Articles), and particulars of directors, shareholders, and company secretary.

For individuals, provide NRIC (Singapore citizens/PRs) or passport and proof of address (utility bill or bank statement, dated within 3 months). For foreign directors or shareholders, supply certified passport copies and proof of residential address. If a nominee director or corporate shareholder is involved, include the corporate entity’s ACRA documents, board resolution, and signed consent forms.

If you intend to apply for an Employment Pass or EntrePass for a foreign director, prepare supporting business plans, financial projections, and background documents. Have details for the registered office address and share capital ready (minimum S$1 capital is acceptable). Ensure all non-English documents are translated and notarised if required.

Online Registration Process

Register the company via ACRA’s BizFile+ portal using a CorpPass or SingPass account, depending on whether you’re filing as an individual or corporate agent. Start by checking and reserving your company name; approval typically takes minutes unless the name requires additional checks.

Complete the incorporation application online: enter director and shareholder particulars, upload the constitution, and declare the registered office and share structure. Pay the government fees (commonly around S$315 total for name reservation and incorporation) and provide electronic identification verification for all parties. Agents such as corporate service providers can file on your behalf; they will need authorisation via CorpPass and the supporting documents mentioned above.

Address any ACRA queries promptly. If ACRA requests clarifications or certified documents, respond within the timeframe given to avoid rejection or delays.

Issuance of Certificate and Company Registration Number

Once ACRA approves the application, you receive the electronic Notification of Incorporation and the Unique Entity Number (UEN). The UEN serves as your company registration number for all government transactions.

Download the electronic Certificate of Incorporation and the company’s Business Profile from BizFile+. The Business Profile lists directors, shareholders, registered address, and UEN and is often required by banks, landlords, and government agencies. Register for corporate tax with IRAS and, if applicable, file for GST registration once thresholds are met.

Store the certificate and business profile securely and provide certified copies when opening bank accounts or applying for licences. If you need physical certified documents, use ACRA-authorised channels or authorised service providers to obtain them.
