UEN Frequently Asked Questions<\/a><\/li>\n<\/ul>\n<\/div>\n\n\n\n<p>When you register a business in Singapore, one of the first details you receive is a Unique Entity Number, commonly called a UEN.<\/p>\n\n\n\n<p>You will need this number regularly. It appears in government filings, tax records, invoices, bank applications and many other business documents. Whether you run a small shop, a growing company or a professional services firm, it is important to know where to find your number and when to use it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section1\"><strong>What is a UEN?<\/strong><\/h2>\n\n\n\n<p>A Unique Entity Number is the official identification number given to a registered business or organization in Singapore.<\/p>\n\n\n\n<p>It works like an identification number for your business. Government agencies use it to recognize your entity and match your submissions, payments and records correctly.<\/p>\n\n\n\n<p>This system also means businesses do not need a different identification number for every government department.<\/p>\n\n\n\n<p class=\"has-dark-gray-color has-text-color has-background has-link-color wp-elements-edec9da8abf01686ebb94e19c0bf60d0\" style=\"background-color:#2164de45\"><strong>Read Also: <a href=\"https:\/\/www.infotech-corp.com.sg\/blog\/how-to-register-company-singapore\/\">Company Registration in Singapore: 2026 Guide<\/a><\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section2\"><strong>Who Needs a Unique Entity Number?<\/strong><\/h2>\n\n\n\n<p>Most registered entities in Singapore receive a Unique Entity Number. These include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Private limited companies<\/li>\n\n\n\n<li>Sole proprietorships<\/li>\n\n\n\n<li>Partnerships<\/li>\n\n\n\n<li>Limited liability partnerships<\/li>\n\n\n\n<li>Foreign companies registered in Singapore<\/li>\n\n\n\n<li>Charities and non-profit organizations<\/li>\n\n\n\n<li>Registered societies<\/li>\n\n\n\n<li>Trade unions<\/li>\n\n\n\n<li>Educational and healthcare institutions<\/li>\n\n\n\n<li>Government and public sector entities<\/li>\n<\/ul>\n\n\n\n<p>A freelancer who has not registered a business may not have it. Once the freelancer registers a sole proprietorship, partnership or company, a Unique Entity Number will be issued.<\/p>\n\n\n\n<p>Individuals use personal identification numbers such as an NRIC or FIN.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Who issues the Unique Entity Number?<\/strong><\/h3>\n\n\n\n<p>Most Singapore businesses receive their UEN from the Accounting and Corporate Regulatory Authority, or <a href=\"https:\/\/www.acra.gov.sg\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>ACRA<\/strong><\/a>.<\/p>\n\n\n\n<p>The number is normally issued automatically when the business registration or company incorporation is approved through <a href=\"http:\/\/bizfile.gov.sg\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Bizfile<\/strong><\/a>. There is usually no separate application.<\/p>\n\n\n\n<p>Some organizations are registered under other government agencies. It may therefore be issued by the agency responsible for that entity type.<\/p>\n\n\n\n<p>Examples include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Registry of Societies for registered societies<\/li>\n\n\n\n<li>Commissioner of Charities for certain charities<\/li>\n\n\n\n<li>Ministry of Education for educational institutions<\/li>\n\n\n\n<li>Ministry of Health for healthcare organizations<\/li>\n\n\n\n<li>Singapore Land Authority for management corporations<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section3\"><strong>What is a Unique Entity Number Used For?<\/strong><\/h2>\n\n\n\n<p>Your UEN will be needed for many everyday business activities.<\/p>\n\n\n\n<p>Common uses include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Opening a corporate bank account<\/li>\n\n\n\n<li>Registering for <a href=\"https:\/\/www.corppass.gov.sg\/portal\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Corppass<\/strong><\/a><\/li>\n\n\n\n<li>Filing corporate income tax with IRAS<\/li>\n\n\n\n<li>Registering for <strong><ins><a href=\"https:\/\/www.infotech-corp.com.sg\/gst-compliance-and-filing-singapore\" target=\"_blank\" rel=\"noreferrer noopener\">GST filing<\/a><\/ins><\/strong><\/li>\n\n\n\n<li>Submitting GST returns<\/li>\n\n\n\n<li>Making CPF-related submissions<\/li>\n\n\n\n<li>Applying for licences and permits<\/li>\n\n\n\n<li>Applying for government grants<\/li>\n\n\n\n<li>Registering for PayNow Corporate<\/li>\n\n\n\n<li>Communicating with government agencies<\/li>\n\n\n\n<li>Issuing business invoices and official documents<\/li>\n<\/ul>\n\n\n\n<p>Banks, customers, suppliers and auditors may also use the Unique Entity Number to confirm the identity of your business.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-background has-link-color wp-elements-71388c9a20e0b73d0efccdb38ae29309\" style=\"background-color:#2164de45\"><strong>Read Also: <a href=\"https:\/\/www.infotech-corp.com.sg\/blog\/cpf-contribution-rate-singapore\/\">CPF Contribution Rate Singapore \u2013 Complete 2026 guide<\/a><\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section4\"><strong>How Do You Get a UEN?<\/strong><\/h2>\n\n\n\n<p>You normally receive it when your business or organization is successfully registered.<\/p>\n\n\n\n<p>For most SMEs, the process is straightforward:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Choose a business structure, such as a sole proprietorship or private limited company.<\/li>\n\n\n\n<li>Register the entity through ACRA\u2019s Bizfile portal.<\/li>\n\n\n\n<li>Submit the required information about the business, owners, shareholders or directors.<\/li>\n\n\n\n<li>Receive the number after the registration is approved.<\/li>\n<\/ol>\n\n\n\n<p>It will appear in the registration confirmation and the entity\u2019s business profile.<\/p>\n\n\n\n<p>Foreign companies establishing a branch or other registered presence in Singapore will receive the number through the relevant registration process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section5\"><strong>What Does a Unique Entity Number Look Like?<\/strong><\/h2>\n\n\n\n<p>It contains letters and numbers.

Enter the business name to view information such as its entity type and current registration status.<\/p>\n\n\n\n<p>Checking the entity status is useful before signing a contract, appointing a supplier or making a large business payment.

The business must update its particulars with the relevant registration agency, but it continues using the same identification number.<\/p>\n\n\n\n<p>A new Unique Entity Number may be issued when a completely new entity is registered or when a business changes to a different legal structure through a new registration.<\/p>\n\n\n\n<p>For example, converting from a sole proprietorship into a private limited company may involve registering a separate legal entity with a new UEN.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section8\"><strong>Can You Choose a Special UEN?<\/strong><\/h2>\n\n\n\n<p>ACRA offers a <a href=\"https:\/\/www.acra.gov.sg\/resources\/guides-forms\/applying-for-special-uen\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Special UEN option<\/strong><\/a> for businesses that prefer a memorable number pattern.<\/p>\n\n\n\n<p>These numbers may contain repeated digits or combinations that are considered easy to remember. Only part of the number can be selected. Details such as the registration-year prefix, entity code and final check alphabet are system-generated.<\/p>\n\n\n\n<p>Special UENs carry an additional fee and are subject to availability. The reference sources describe <a href=\"https:\/\/www.bizfile.gov.sg\/special-uen\/getting-started\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>two selection tiers<\/strong><\/a>, commonly priced at S$1,000 and S$3,000 depending on the number pattern.
