What Is UEN in Singapore? A Complete Guide for Businesses
If you are starting or operating a business in Singapore, you will come across the term UEN, or Unique Entity Number, quite frequently. Whether you are registering a company, dealing with government agencies, managing tax matters, or checking a business’s registration details, the UEN is an important business identifier.
In simple terms, a UEN is a unique identification number assigned to an entity in Singapore. It allows government agencies and businesses to identify the same entity consistently across different transactions and regulatory processes.
For business owners, understanding how the UEN works can make company administration and compliance much easier. This guide explains what a UEN is, where to find it, what it is used for, and how it differs from a GST registration number.
What Does UEN Mean in Singapore?
UEN stands for Unique Entity Number.
It is a unique identifier assigned to registered entities in Singapore. The UEN system was introduced to provide entities with a common identification number when interacting with government agencies.
Instead of having to manage different identification numbers for different government transactions, an entity can use its UEN as its primary business identifier.
The UEN is relevant to various types of Singapore entities, including companies, businesses, limited liability partnerships and other registered organisations. ACRA’s entity search also allows users to look up registered entities using their business name or UEN.
Is UEN the Same as a Company Registration Number?
In many business contexts, people use terms such as “company registration number” and “UEN” interchangeably. For a Singapore-registered company, the UEN serves as the entity’s official identification number.
However, the exact UEN format can differ according to the type of entity and when or how it was registered. Therefore, you should not assume that every Singapore UEN follows the same pattern.
What Is a UEN Used For?
The UEN is an important part of Singapore’s business administration system.
Businesses may need their UEN when carrying out activities such as:
- Communicating or transacting with government agencies
- Accessing corporate government services
- Filing regulatory information
- Managing tax-related matters
- Checking or verifying business information
- Completing corporate documentation
- Conducting certain business and financial transactions
For example, ACRA’s Bizfile entity search allows users to search for an entity by its name or UEN and view basic information such as its status and registered address.
Your UEN is therefore an important piece of information that should be kept with your company’s key corporate records.
Who Receives a UEN in Singapore?
UENs are not restricted to private limited companies.
Different categories of registered entities can have a UEN. Depending on the entity type, the relevant registration or issuing authority may differ. ACRA issues UENs for many business and corporate entities registered under its administration.
Examples can include:
- Private and public companies
- Sole proprietorships
- Partnerships
- Limited liability partnerships (LLPs)
- Limited partnerships
- Public accounting firms
- Other registered organisations
The exact registration requirements and UEN format depend on the type of entity.
What Does a Singapore UEN Look Like?
There is no single UEN format for every entity.
For example, UENs may contain a combination of numbers and letters, with different formats used for different entity types and registration periods.
Some UENs may begin with the year of incorporation or registration, while others use different prefixes. ACRA notes that the first four digits of certain company UENs can indicate the year of incorporation.
Because formats vary, it is better to verify an entity’s UEN through an official source rather than trying to determine whether a number is valid based only on its appearance.
How Do I Find a Company’s UEN in Singapore?
If you need to check a company’s UEN, you can use ACRA’s Bizfile entity search.
The general process is:
- Go to the Bizfile entity search.
- Search using the company’s registered name or UEN.
- Review the matching entity.
- Check the available business information, including the UEN and registration status.
ACRA’s current Bizfile search allows users to search by entity name or UEN, including previous UENs where applicable.
This can be useful when verifying a supplier, customer, business partner or company before entering into a commercial relationship.
Is a UEN Free?
A standard UEN is issued as part of the applicable business registration process and does not require a separate fee simply for receiving the standard number.
Singapore also has an option known as a Special UEN (SUN). This allows eligible applicants registering a new entity to select a memorable UEN from available number patterns for an additional fee. ACRA currently lists two SUN pricing tiers: S$3,000 and S$1,000, depending on the selected number pattern.
The Special UEN option is different from the ordinary UEN that is assigned during registration.
What Is the Difference Between UEN and GST Registration Number?
UEN and GST registration numbers are related to business administration, but they serve different purposes.
UEN
The Unique Entity Number identifies the business or entity.
It is used broadly when the entity interacts with Singapore government agencies and for various corporate processes.
GST Registration Number
A GST registration number relates specifically to an entity’s registration for Goods and Services Tax purposes.
Therefore, a business should not automatically assume that its UEN and GST registration details are interchangeable for every purpose.
If your business is GST-registered, keeping your corporate and tax records properly organised can help reduce administrative errors.
Why Is UEN Important for Business Owners?
A UEN may look like a simple identification number, but it plays an important role in business administration.
- It provides a consistent business identifier
Using a common entity identifier makes it easier for businesses and government agencies to identify the correct organisation.
- It helps with regulatory administration
Businesses regularly interact with agencies for tax, corporate and regulatory matters. The UEN helps connect these transactions to the correct entity.
- It supports business verification
A potential customer, supplier or business partner can use official business information to verify an entity’s registration details.
- It is useful for accounting and compliance
Accounting, tax and corporate compliance work often requires accurate company information. Keeping your UEN readily available helps ensure that documents and submissions are associated with the correct entity.
UEN and Accounting: Why Accuracy Matters
Your UEN is one of the basic pieces of information an accountant or corporate service provider may need when handling your company’s administrative and compliance matters.
For businesses that outsource bookkeeping, accounting or tax work, maintaining accurate company information is especially important. Your accounting records may need to connect with corporate filings, tax submissions and other regulatory processes.

For businesses that need broader support, WLP also provides accounting, tax, corporate secretarial and payroll-related services.
What Should Businesses Do After Receiving a UEN?
Once your business has been successfully registered, keep your UEN together with other important corporate information.
A practical business records checklist can include:
- Company or business name
- UEN
- Date of incorporation or registration
- Registered office address
- Business activities
- GST registration details, if applicable
- Corporate secretarial records
- Accounting and tax records
- Relevant government account information
Maintaining an organised record of these details can make future compliance and administrative work more straightforward.
