Understanding UEN in Singapore

If you’re planning to start a business in Singapore, it’s important to understand the Unique Entity Number (UEN) system. UEN is a system-generated identification number that is used to identify and track business entities in Singapore. Here’s what you need to know about UEN in Singapore.
The Basics of UEN
UEN is a standard identification number that is issued to all registered business entities in Singapore. It is a 9 or 10-digit number that is unique to each business entity. The UEN system was introduced by the Accounting and Corporate Regulatory Authority (ACRA) in Singapore to streamline the business registration process and make it easier for government agencies to interact with businesses.
Types of UEN and Entities
There are different types of UENs that are issued to different types of entities in Singapore. The most common types of UENs are:
- Local companies: These are companies that are incorporated in Singapore and have a UEN that starts with the first two digits of their incorporation number.
- Business entities: These are sole proprietorships, partnerships, and limited liability partnerships that are registered with ACRA.
- Special UENs: These are UENs that are issued to government agencies, town councils, embassies, and other entities that are not registered with ACRA.
The Registration Process
The UEN is issued free of charge when you successfully incorporate your business entity with ACRA. The UEN is system-generated and will be sent to you via email or SMS once your business entity is registered. If you have not received your UEN, you can check it online using the Singapore UEN lookup system.
To apply for a UEN, you must first register your business entity with ACRA. The registration process involves providing information about your business entity, such as its name, address, and entity type. Once your business entity is registered, you will be issued a UEN that you can use for all your interactions with government agencies.
In conclusion, understanding the UEN system is crucial for any business entity in Singapore. It is a unique identifier that is used by government agencies to interact with businesses. By following the registration process and obtaining a UEN, you can ensure that your business entity is properly identified and tracked in Singapore.
Using UEN for Business Operations

As a business entity registered with ACRA, you can use your Unique Entity Number (UEN) for various business operations. Here are some of the ways in which you can use your UEN:
Business Transactions with UEN
When transacting with customers or suppliers, you can use your UEN to identify your business entity. This can be useful for financial transactions, such as payments and credit applications. By providing your UEN, you can ensure that your business is easily identifiable and legitimate.
Compliance and Reporting
Your UEN is also important for compliance and reporting purposes. For instance, you need to include your UEN on your invoices, receipts, and other business documents. This helps to ensure that your business is compliant with the relevant regulations and requirements.
Additionally, you need to use your UEN when filing your corporate tax returns and GST registration. This is important for tax purposes and can help to avoid any penalties or fines for non-compliance.
Special UENs
Some business entities may have special UENs, such as those issued to sub-entities, partnerships, or representative offices. These UENs may have different formats or requirements, so it’s important to check the relevant guidelines and regulations.
UEN and Business Structure
Your UEN is closely tied to your business structure and registration number. For instance, if you are a sole proprietorship, your UEN will be your NRIC number. If you are a local company, your UEN will be your ACRA registration number.
UEN and Government Agencies
Your UEN is also important for interacting with government agencies, such as the Department of Statistics, IRAS, and Ministry of Law. For instance, you may need to provide your UEN when applying for licenses, permits, or exemptions.
Conclusion
Overall, your UEN is a crucial identification number for your business entity. By using your UEN for business transactions, compliance, and reporting, you can ensure that your business is legitimate and easily identifiable.
