Choosing the right business name is the first legal step for any enterprise in Singapore. Under the Companies Act and the Accounting and Corporate Regulatory Authority (ACRA) guidelines, every sole proprietorship, partnership, LLP, or company must register its name before it can legally operate.
This pillar guide breaks down the definition of a Singapore business name, the eligibility criteria, reservation and registration processes, sector‑specific rules, and the penalties for non‑compliance, giving you a clear roadmap to secure a compliant and market‑ready name.
Quick Answer: A Singapore business name must be reserved and approved by ACRA before use, complying with the Companies Act's naming rules and any sector‑specific restrictions.
Key Takeaways
- Reserve your name online via ACRA's BizFile+ and wait up to 30 days to incorporate.
- Avoid prohibited words and ensure the name is not identical or too similar to existing entities.
- Include the correct entity suffix (e.g., Pte Ltd, LLP) as required by law.
- Foreign owners can register a name but must meet local director or shareholder requirements.
- Failure to register or using a prohibited name can result in fines, injunctions, or forced name changes.
What is a Singapore business name and why is registration required?
Quick Answer: A Singapore business name is the official identifier under which a business trades, and registration with ACRA is mandatory to secure exclusivity and legal enforceability.
Under Section 11 of the Companies Act (Cap 50), every entity that carries on business must adopt a name and lodge it with the Accounting and Corporate Regulatory Authority (ACRA). Registration creates a public record, prevents duplication, and enables the name to be used in contracts, invoices and legal proceedings. Failure to register renders the name “unregistered” and the business may be deemed to be operating illegally.
Exception: a natural person may use his/her own name without registration, but any deviation or addition still requires registration.
How does Singapore define “restricted” and “prohibited” business names?
Quick Answer: “Restricted” names are those requiring prior approval or additional documentation, while “prohibited” names are outright disallowed under the Companies Act.
Section 12 of the Companies Act lists restricted names, e.g., those containing “Bank”, “Insurance”, “University”, or a name that suggests a connection with a government body; approval must be obtained from the relevant regulator (MAS, MCA, etc.). Section 13 enumerates prohibited names, such as those that are obscene, scandalous, or likely to mislead the public. ACRA will reject applications that fall within these categories.
Key point: Even if a name is not on the list, ACRA may refuse it if it is likely to cause confusion with an existing entity.
When does a business need to register its name with ACRA versus using a trade name?
Quick Answer: All legal entities must register their primary business name with ACRA; a separate trade name can be used only after registration and must be disclosed in the business profile.
Registration of the primary name is compulsory under Section 11 of the Companies Act. A trade name (or “doing‑business‑as” name) may be adopted for marketing, but it does not replace the registered name and must be recorded in the entity’s particulars with ACRA. Failure to disclose a trade name can result in penalties for non‑compliance with filing obligations.
Exception: Sole proprietors may operate under their own personal name without a separate trade name, but any other name still requires registration.
Which entities (sole proprietorship, partnership, LLP, company) are subject to Singapore name registration rules?
Quick Answer: All entities that are legal persons—sole proprietorships, partnerships, limited liability partnerships (LLPs) and companies—must register a business name with ACRA.
The Companies Act (Section 11) applies to companies and LLPs, while the Business Names Registration Act (effective 1 Nov 2020) extends the same requirement to sole proprietorships and partnerships. Each entity must submit a name reservation and, upon approval, file the name in its registration documents. The rule ensures a uniform public register across all business structures.
Key distinction: Companies must also include a suffix (e.g., “Pte Ltd”), whereas LLPs must use “LLP”; sole proprietorships and partnerships have no suffix requirement.
What are the eligibility criteria for reserving a business name in Singapore?
Quick Answer: The name must be available, not restricted or prohibited, and the applicant must meet the statutory eligibility requirements for the chosen entity type.
ACRA’s online portal checks availability against the existing register. The applicant must be a Singapore‑resident individual or a registered entity, possess the necessary qualifications (e.g., a local director for a company), and provide a valid identification number (NRIC/FIN). For foreign applicants, a local resident director or authorized representative is required. The name cannot be identical or confusingly similar to an existing name, nor can it contain restricted words without approval.
Exception: Names consisting solely of the applicant’s surname and given name are exempt from the “identical” test.
What disclosures must be included in a Singapore business name (e.g., “Pte Ltd”, “LLP”)?
Quick Answer: Companies must append “Pte Ltd” (or “Ltd”) and LLPs must append “LLP”; sole proprietorships and partnerships have no mandatory suffix.
Section 11(2) of the Companies Act mandates that a company’s name end with “Private Limited” (commonly abbreviated “Pte Ltd”) or “Limited” for public companies. The Limited Liability Partnerships Act requires the suffix “LLP”. The suffix signals the legal nature of the entity and informs third parties of the extent of liability. Failure to use the correct suffix constitutes a breach of the Act and may attract fines.
Key note: The suffix must appear exactly as prescribed; variations (e.g., “Pte. Ltd.”) are not acceptable.
How do you reserve a Singapore business name online and what is the typical processing time?
Quick Answer: Use ACRA’s BizFile+ portal to submit a name reservation; approval is usually instantaneous, but may take up to 2 working days for names requiring additional checks.
Log in to BizFile+, select “Reserve a Business Name”, enter up to three preferred names, and pay the S$15 reservation fee. The system conducts an automated search against the register. If the name is unrestricted and available, approval is generated within minutes. For restricted names, ACRA forwards the request to the relevant regulator, extending the processing period to a maximum of 2 working days.
Note: The reservation is valid for 60 days and can be renewed once for an additional 60 days.
What are the steps to register a business name after reservation is approved?
Quick Answer: Submit the incorporation or registration filing on BizFile+ within the reservation period, attaching the approved name reservation and required statutory documents.
1. Log in to BizFile+ and choose the appropriate entity type. 2. Upload the Name Reservation Confirmation (valid ≤ 60 days). 3. Complete the incorporation form (e.g., “Register a Business” for sole proprietorships, “Incorporate a Company” for companies). 4. Pay the filing fee (e.g., S$300 for a company). 5. ACRA issues the Business Registration Certificate within 1 working day if all documents are in order.
Key deadline: Registration must occur before the reservation expires, otherwise a new reservation is required.
Can a foreigner register a Singapore business name without a local director?
Quick Answer: No; a foreign applicant must appoint at least one Singapore‑resident director or authorized representative to satisfy ACRA’s residency requirement.
Section 157 of the Companies Act requires every company to have at least one director who is ordinarily resident in Singapore. For sole proprietorships and partnerships, a local resident partner is similarly required. The resident can be a Singapore citizen, permanent resident, or holder of an Employment Pass/EntrePass. The foreigner may hold the remaining shareholding and can be the sole shareholder, but the resident director’s consent is mandatory.
Exception: A foreign‑incorporated company may register a branch office without a local director, but the branch must appoint a local “authorized representative”.
How to change or update a Singapore business name after incorporation?
Quick Answer: File a “Change of Company Name” with ACRA via BizFile+, obtain board and shareholder approval, and pay the prescribed fee.
Under Section 13 of the Companies Act, a company may alter its name by passing a special resolution (≥ 75 % of votes) at a general meeting, then filing Form CH01 within 14 days of the resolution. The new name must pass the same availability and restriction checks as an initial reservation. Once ACRA approves, a new Certificate of Incorporation with the updated name is issued.
Key point: The old name remains protected for 30 days after the change, preventing third parties from registering it immediately.
What are the naming rules for businesses in regulated sectors such as financial services, legal, and healthcare?
Quick Answer: Regulated sectors must obtain prior approval from the relevant regulator before adopting a name that suggests the provision of regulated services; otherwise the name is prohibited under the Companies Act and sector‑specific statutes.
Under the Companies Act (Cap 50) s.23, a company name may not be “identical or confusingly similar” to an existing name or to a name that implies the company is a bank, insurance company, legal practitioner, or healthcare provider unless the name has been approved by the Monetary Authority of Singapore (MAS), the Legal Profession Board, or the Ministry of Health. ACRA’s “Regulated Business Names” guidance (ACRA 2023) lists prohibited terms such as “bank”, “insurance”, “lawyer”, “doctor”, “clinic”, and “hospital”. The Health Services Act (Cap 224) and the Legal Profession Act (Cap 229) further prohibit the use of titles that could mislead the public about professional status.
- Apply to the regulator for approval before filing with ACRA.
- Failure to obtain approval results in refusal or cancellation of the name.
Are there exemptions for using a “doing business as” (DBA) name in Singapore?
Quick Answer: No, every DBA (trade name) must be registered with ACRA; there are no statutory exemptions for using an unregistered alias.
Under the Companies (Registration of Business Names) Regulations 2015 (Cap 50, Reg 3), a company, sole proprietorship or partnership must file a “business name” with ACRA before it can be used publicly. The name must be unique and not misleading under s.23 of the Companies Act. Sole proprietors and partnerships may register a business name in their own name, but the name still requires ACRA approval. Failure to register results in the DBA being deemed invalid and the entity may be fined under the Companies Act or the Business Names Act.
- Register the DBA within 30 days of commencement of business.
- Renew the registration annually; non‑renewal leads to cancellation.
What happens if a reserved name is not used within the 30‑day registration window?
Quick Answer: The reservation lapses after 30 days, the name is released back to the pool, and the applicant must re‑reserve it if still desired.
Under the Companies (Reservation of Company Names) Regulations 2015 (Cap 50, Reg 2), a name reservation is valid for 30 days from the date of approval. If the applicant does not file the incorporation or registration documents within that period, ACRA automatically cancels the reservation and the name becomes available for any other applicant. No fine is imposed, but the applicant loses the exclusive right to the name and may incur additional costs if re‑reserving.
- Re‑reserve the name within 24 hours of cancellation to avoid competition.
- Consider using a different name to avoid delays.
What penalties apply for using an unregistered or prohibited business name in Singapore?
Quick Answer: ACRA can impose a fine of up to SGD 10,000, cancel the company’s registration, and for repeated or intentional offences, criminal prosecution may lead to up to 2 years’ imprisonment.
Under s.23 of the Companies Act, using a name that is identical or confusingly similar to an existing name or that is prohibited by regulation is an offence. ACRA may issue a penalty notice (up to SGD 10,000) and may cancel the company’s name registration. For repeated violations or for use of a name that misleads the public, the Director of the Registrar may refer the matter to the Director of Public Prosecutions, where the offence is punishable under s.24 as a criminal offence with a maximum penalty of 2 years’ imprisonment and/or a fine of SGD 20,000 (as of 2026).
- Immediate cessation of the prohibited name is required to mitigate penalties.
- Appeal the penalty notice within 30 days of receipt.
How can a business contest a rejected name application?
Quick Answer: The applicant may file a written appeal with ACRA within 30 days of the rejection, providing evidence that the name is not misleading and is not identical or confusingly similar to an existing name.
Under s.23 of the Companies Act and the Companies (Registration of Business Names) Regulations 2015, an applicant may submit a written request to the Registrar of Companies for reconsideration. The appeal must include the original name, the reason for rejection, and any supporting documents (e.g., trademark registration, evidence of distinctiveness). ACRA will review the appeal and may approve the name, refuse again, or refer the matter to the Companies Tribunal for adjudication. The Tribunal’s decision is final and binding.
- File the appeal electronically via ACRA’s BizFile+ portal.
- Respond to any ACRA queries within 14 days to avoid dismissal.
How to conduct a name availability search and avoid similarity conflicts?
Quick Answer: Use ACRA’s BizFile+ “Name Availability Search” and the “Similar Name Search” feature, then cross‑check with IPOS trademarks to ensure the proposed name is not identical, confusingly similar, or infringing.
On BizFile+, select “Company Registration” → “Name Availability Search” and enter the proposed name. ACRA returns a list of existing names and flags any that are identical or similar. The “Similar Name Search” applies a similarity algorithm based on the Companies (Registration of Business Names) Regulations 2015. After confirming availability, search the IPOS database for registered trademarks that could conflict. If a conflict is

Frequently Asked Questions
Can I use a foreign company name for my Singapore business?
Yes, you can use a foreign company name provided it is not identical or confusingly similar to an existing Singapore entity. ACRA requires that the name be distinct and not infringe on trademarks. It is advisable to conduct a trademark search and obtain legal advice before finalizing the name.
What should I do if my preferred business name is already taken?
In that case, you have two options: (1) choose an alternative name that is available, or (2) request a name reservation for a short period (up to 30 days) and submit a name change application if you wish to use the original name. ACRA will review the request and may approve it if it meets all statutory criteria.
Are there restrictions on certain words or phrases in a business name?
Yes. Words that imply a connection with the government, public institutions, or that are deemed offensive, misleading, or prohibited by law (e.g., “Bank,” “Insurance,” “University”) are disallowed. ACRA’s guidelines list prohibited words and phrases; consult the ACRA website for the most up‑to‑date list.
How long does the registration process typically take?
Under normal circumstances, ACRA processes most applications within 1–3 business days. However, if additional documentation is required or the name is contested, the process may take longer. Using the online BizFile+ system and ensuring all documents are complete can expedite approval.
Can I register a business name without forming a company?
No. In Singapore, a business name must be registered under a corporate entity (company, partnership, or sole proprietorship). ACRA requires a legal entity to hold the name; otherwise, the name cannot be used for official purposes.
What are the penalties for using a prohibited or misleading business name?
ACRA may issue a warning, demand a name change, or, in severe cases, impose fines up to SGD 10,000. Repeated violations can lead to revocation of the company’s registration and criminal charges under the Companies Act.
How can I change a registered business name after incorporation?
File a name change application through BizFile+ and provide the new name’s availability confirmation. ACRA will review the request and, if approved, issue a new Certificate of Incorporation reflecting the updated name. All company documents and records must be updated accordingly.
Is it permissible to register a business name that includes my personal name?
Yes, provided the name is not misleading or deceptive. ACRA will assess whether the name could cause confusion or imply a professional qualification. If the name is accepted, you must still comply with all other naming rules.
