What Is a UEN in Singapore? Complete Guide for Businesses

If you are starting or operating a business in Singapore, you will come across the term UEN quite often. Whether you are opening a corporate bank account, filing documents with government agencies, issuing invoices, or handling business transactions, your UEN is an important business identifier.

But what is a UEN in Singapore, and why does your company need one?

A Unique Entity Number (UEN) is a unique identification number assigned to businesses and other entities registered or recognised in Singapore. It is used by government agencies and businesses to identify an entity and simplify administrative and regulatory processes.

For entrepreneurs setting up a new company, understanding the UEN number in Singapore is an important part of managing corporate compliance.

In this guide, we explain what a UEN is, who needs one, where to find it, how it is used, and what businesses should know about managing their UEN.

What Is a UEN in Singapore?

A Unique Entity Number (UEN) is a standard identification number given to entities operating or registered in Singapore.

The UEN acts as a unique identifier for your business when dealing with government agencies, financial institutions, customers, suppliers, and other organisations.

For example, when you register a company with the Accounting and Corporate Regulatory Authority (ACRA), your company is issued a UEN. This number is then used for various business and administrative purposes.

Think of your UEN as an identification number for your business. Instead of providing different identification numbers to different government agencies, businesses can use their UEN for many official transactions.

Example of a UEN

A Singapore company may have a UEN such as:

201912345A

The exact format of a UEN can vary depending on the type of entity and when it was registered.

Why Is a UEN Important for Businesses in Singapore?

Your UEN number Singapore is more than just a registration reference. It is an important identifier used throughout the lifecycle of your business.

Businesses may need their UEN for:

• Corporate bank account applications

• Government transactions

• Tax-related matters

• Business licences and permits

• Corporate filings

• CPF-related transactions

• Import and export activities

• Invoicing and business documentation

• Applying for government services

• Communicating with government agencies

• Updating business information

Having your UEN readily available can make many administrative processes faster and easier.

For companies, keeping accurate corporate information associated with the UEN is also important for maintaining proper compliance.

Who Gets a UEN in Singapore?

Most businesses and registered entities that need to interact with Singapore government agencies will have a UEN.

These may include:

• Private limited companies

• Limited liability partnerships

• Partnerships

• Sole proprietorships

• Limited partnerships

• Certain trusts

• Societies and other registered organisations

• Government-related entities

However, the specific UEN format can differ depending on the entity type and the authority responsible for registration.

For companies incorporated with ACRA, the UEN is generally provided as part of the business registration process.

UEN vs Company Registration Number: Are They the Same?

One common question among business owners is whether a UEN is the same as a company registration number.

For many Singapore-registered companies, the UEN serves as the company's primary identification number. However, terminology and numbering formats can vary depending on the entity and registration authority.

You may also hear terms such as:

• Company registration number

• Registration number

• Business registration number

• UEN

• ACRA registration number

In many everyday business situations, these terms may refer to the identifier associated with the entity's registration.

If you are unsure which number should be used on a particular form or document, it is best to check the requirements of the relevant government agency or service provider.

Where Can You Find Your UEN in Singapore?

If your business is already registered, finding your UEN in Singapore is relatively straightforward.

1. Check Your ACRA Business Profile

For businesses registered with ACRA, your UEN can be found on your official business registration information or Business Profile.

The Business Profile contains important information about your company, including details such as:

• Company name

• UEN

• Registered address

• Company status

• Principal business activities

• Directors

• Shareholders

• Other registered information

2. Search on BizFile

BizFile is ACRA's online platform for business registration and corporate filing services.

You can use the platform to search for registered business information and access relevant company records.

When searching for a company, information associated with its UEN can help confirm that you are looking at the correct entity.

3. Check Your Company Documents

Your UEN may also appear on documents such as:

• Invoices

• Contracts

• Business letters

• Bank documents

• Tax-related documents

• Government correspondence

• Corporate records

Businesses should maintain consistent and accurate information across their official documents.

How Do You Get a UEN in Singapore?

For a new business, the process depends on the type of entity you are registering.

If you are incorporating a private limited company, the company registration process with ACRA results in the assignment of a UEN once the entity is successfully registered.

The general company setup process includes:

Step 1: Choose a Business Structure

Decide whether you want to establish a private limited company, sole proprietorship, LLP, or another suitable structure.

Step 2: Choose and Reserve Your Business Name

The proposed company name must be submitted for approval before incorporation.

Step 3: Prepare Company Information

Depending on the business structure, you may need information such as:

• Company name

• Registered office address

• Business activities

• Share capital details

• Shareholder information

• Director information

• Company secretary details

Step 4: Submit the Registration

The application is submitted through the appropriate registration process.

Step 5: Receive Your UEN

Once the company is successfully registered, the business receives its UEN and can use it for official business and administrative transactions.

Working with a professional corporate secretary in Singapore can help businesses manage the registration and compliance process more efficiently.

What Is the Difference Between UEN and GST Registration Number?

UEN and GST registration are related to your business but serve different purposes.

The UEN identifies the business entity, while GST registration relates to a business's registration for Goods and Services Tax.

Not every business is necessarily GST-registered.

Therefore, having a UEN does not automatically mean that your company is GST-registered.

If your business is registered for GST, additional GST-related information may be relevant when issuing tax invoices and handling GST matters.

What Is the Difference Between UEN and Tax Identification?

A UEN is primarily an entity identifier, while tax-related identification is used for taxation purposes.

For Singapore businesses, the UEN can be used in interactions with government agencies, including certain tax-related processes. However, businesses should always follow the specific requirements provided by the relevant authority.

Understanding the difference between company registration, UEN, GST, and tax-related obligations can help businesses avoid administrative mistakes.

Is a UEN Required on Business Invoices?

Businesses should include appropriate company information on invoices and other commercial documents.

Depending on the nature of the transaction and applicable requirements, this may include your:

• Registered company name

• UEN

• Registered address

• Contact details

• Invoice number

• Payment information

• GST registration details, where applicable

Including the correct UEN can make it easier for customers, suppliers, financial institutions, and other parties to identify your company.

Can a UEN Change?

In most cases, a company's UEN remains associated with the entity throughout its existence.

However, businesses should not assume that every change to their company information will have the same effect on their registration details.

For example, changing your:

• Company name

• Registered address

• Directors

• Shareholders

• Business activities

does not necessarily mean that your UEN will change.

If your company undergoes a restructuring, conversion, or other significant change, the applicable registration rules should be checked with the relevant authority.

How Can Businesses Use Their UEN?

Your UEN can be used in many areas of business administration.

Government Transactions

Government agencies can use the UEN to identify your business and process corporate-related transactions.

Corporate Compliance

Businesses may use their UEN when completing corporate filings and maintaining company records.

Banking

Banks may request your UEN when opening or maintaining a corporate bank account.

Business Contracts

Including accurate company identification information in contracts can help clearly identify the legal entity involved.

Invoicing

The UEN can be included in invoices and other business documents to identify your company.

Licences and Permits

Certain business licences and regulatory applications may require your UEN.

Why Corporate Compliance Matters After Getting a UEN

Getting a UEN is only one part of establishing a business in Singapore.

Once your company is incorporated, you may have ongoing responsibilities such as:

• Maintaining statutory registers

• Filing annual returns

• Updating company information

• Maintaining accounting records

• Preparing financial statements where required

• Holding required company meetings

• Maintaining corporate records

• Complying with applicable tax obligations

This is where professional corporate secretarial services in Singapore can be valuable.

A corporate secretary can help businesses stay organised and meet important corporate compliance requirements while business owners focus on daily operations and growth.

A UEN in Singapore is one of the most important identification details associated with a registered business. From government transactions and corporate filings to banking, contracts, and business documentation, your UEN can be used across many aspects of running a company.
