Singapore Company Registration Number Sample and How to Read It
Every legally registered business entity in Singapore is assigned an official identification number known as the Unique Entity Number (UEN). If you are reviewing a singapore company registration number sample, understanding how this alphanumeric code is structured allows you to verify business contracts, issue compliant commercial invoices, and file statutory reports with government agencies. Issued by ACRA upon successful incorporation, the UEN serves as your company’s universal identifier across all regulatory, tax, and commercial interactions.
Whether you are inspecting incoming vendor documentation or printing your own official stationery, knowing how to interpret the UEN ensures total administrative compliance.
Decoding the Modern Singapore UEN Format
A Singapore company registration number (UEN) for modern private limited companies consists of 10 characters: the 4-digit year of incorporation (e.g., 2026), a 5-digit sequential code (e.g., 12345), and a final check letter (e.g., K). This standardized identifier is mandatory on all commercial invoices and contracts.
Singapore standardized its entity numbering system to streamline cross-agency reporting across ACRA, IRAS, and customs authorities. Here is how modern UENs are structured:
Standard 10-Digit Format for Local Companies: For private limited companies incorporated after January 1, 2009, the UEN follows a structured 10-character alphanumeric formula:
**Year of Incorporation (First 4 Digits):** Indicates the year the entity was registered with ACRA (e.g., `2026`).Entity Type & Sequential Code (Next 5 Digits): A unique sequential number generated by the national database (e.g.,
12345).Check Character (Final Letter): An algorithmic verification letter (e.g.,
K).Example Modern UEN:
202612345K- **Format for Sole Proprietorships and Partnerships:** Businesses registered as sole proprietorships or standard partnerships use an 8-digit format followed by a check letter (e.g., `12345678X`).
- **Foreign Entities and Other Specialized Entities:** Foreign branch offices and representative offices feature specialized entity indicators (e.g., `T26FC1234K`).
- **Statutory Rules for Displaying Your UEN:** Under the Singapore Companies Act, every company must clearly display its registered corporate name and UEN on all business documents, including commercial invoices, official websites, receipts, and formal business letters.

Frequently Asked Questions About Singapore UEN Numbers
Is the UEN the same as the company’s GST and Corporate Tax Number?
Yes. Singapore utilizes the UEN as the single corporate tax reference number for IRAS corporate income tax filings and GST reporting.
Can a company change its UEN number after incorporation?
No. The UEN is permanently assigned to the legal entity for its entire corporate lifespan and cannot be modified even if the company changes its name.
