How to choose a company name in Singapore that ACRA will approve?
ACRA approves names that are unique, not identical or confusingly similar to any existing registered name, not undesirable (offensive/vulgar), and without restricted words (e.g., "Bank", "University", "Temasek") unless prior approval is obtained. Names are reserved for 120 days upon approval; cost S$15 via Bizfile+. Premium tip: combine a coined word with a descriptive term to maximise distinctiveness and trademark potential.

1. ACRA naming rules & similarity traps
Under the Companies Act (Cap. 50) and the Business Names Registration Act 2014, ACRA will reject names that are identical, too similar, or undesirable. However, the registrar disregards certain common words when comparing names — a nuance where many entrepreneurs fail. See ACRA's official naming guidelines for the full list.
"The most frequent rejection we see is entrepreneurs adding 'International' or 'Singapore' to an existing name and assuming it's new. ACRA will still treat it as identical. Instead, create a coined or abstract term (e.g., 'Novus', 'Zentic') and attach it to your descriptor. That is the formula for first‑time approval."
Processing timeline: Straightforward names: 15 minutes–1 business day. Names requiring referral (restricted words): 14–60 days.
Once your name is approved, the next step is Singapore incorporation — where your reserved name is locked in for 120 days while you complete director, shareholder, and registered address setup.
2. Restricted words & referral authorities
| Category | Examples | Referral authority |
|---|---|---|
| Financial services | Bank, Insurance, Finance, Fund, Capital, Investment | Monetary Authority of Singapore (MAS) |
| Education | School, University, College, Academy, Institute | Ministry of Education (MOE) |
| Medical/healthcare | Clinic, Hospital, Medical, Dental, Healthcare | Ministry of Health (MOH) |
| Legal/professional | Lawyer, Attorney, Architect, Engineer | Professional regulatory bodies |
| Protected names | Temasek, Singapore (contextual), National, Republic | Various government agencies |
Tip: If your name requires referral authority approval, our corporate secretarial services team can manage the paperwork and liaison with MAS/MOE/MOH to avoid delays. For a complete checklist of all requirements, see our Singapore company incorporation requirements for 2026 guide.
3. "Identical" deep dive – what ACRA disregards
When checking for identical names, ACRA ignores the following words and characters. Removing or adding them does not make your name unique.
4. Real case studies: rejected vs. approved
❌ Case A – Rejected: "Singapore Elite Consulting"
Reason: Too similar to existing "Elite Consulting Pte Ltd". ACRA disregarded "Singapore" and "Pte Ltd", leaving "Elite Consulting" → identical to existing name.
Fix: Client changed to "Novus Elite Consulting" — the coined word "Novus" created distinctiveness and was approved within 2 days.
✅ Case B – Approved (with referral): "Oaktree Learning Hub"
Challenge: "Learning Hub" triggered MOE referral (education). The client obtained a letter of non-objection from MOE after proving they offered only enrichment courses (not MOE-registered curriculum). ACRA approved after 34 days. Lesson: Plan 30–60 days if using restricted words.
⚠️ Case C – ACRA approved, but trademark blocked: "Zentic Labs"
ACRA approved the name, but a U.S. tech company already owned the trademark "ZENTIC". After a cease & desist letter, the Singapore company rebranded within 8 months, costing over S$12,000. Takeaway: Always run an IPOS trademark search before finalising your name. If you need help with trademark clearance and registration, our team can conduct comprehensive searches across Singapore and key regional markets. For foreign entrepreneurs, understanding foreign business registration options also helps avoid naming conflicts across jurisdictions.
5. Decision flowchart: will ACRA approve your name?
├─ YES → ➔ Obtain approval from referral authority (MAS/MOE/MOH) → ➔ Add to ACRA application → 🟢 proceed
└─ NO → ➔ Remove all disregarded words (Pte, Ltd, Singapore, Group…) → ➔ Compare the core phrase with ACRA register
├─ Core phrase identical to existing registered name? → ❌ REJECTED → ➔ Add a coined word (e.g., "Kodō", "Aerix", "Viventi")
└─ Core phrase unique? → 🟢 Submit via Bizfile+ → Approved (typically 1 day)
6. Coined‑word scoring rubric (proprietary tool)
Premium corporate secretaries use a scoring matrix to evaluate coined names. Score your proposed name below:
Scoring threshold: 20–25 = excellent; 15–19 = moderate risk; below 15 → reconsider before applying.
7. Trademark & domain: why ACRA approval is not enough
ACRA approves company names, not trademarks. Two different legal frameworks. Even after incorporation, an existing trademark owner can force you to change your name via a passing-off action.
- Search IPOS trademark e-Search before submitting name to ACRA.
- Check .com.sg / .sg availability via SGNIC.
- Register your own trademark within 6 months of incorporation to secure brand protection.
For foreign entrepreneurs evaluating Singapore as a regional base, understanding business registration options (Pte Ltd vs Branch vs LLP) also affects naming strategy — some structures have different naming conventions and restrictions. Your choice of business structure also determines whether you need a resident director and affects your naming flexibility.

9. Frequently Asked Questions
What is the fastest way to get ACRA name approval?
Choose a coined word + descriptor (e.g., "Aerix Logistics"), avoid restricted words, and ensure no existing identical core phrase. Straightforward applications are approved within 1 business day.
How long is a reserved name valid?
120 days from approval. If you don't incorporate within that window, the name lapses and becomes available to others.
Can I appeal a name rejection?
Yes. You can submit an appeal via Bizfile+ or propose a new name. However, appeals rarely succeed unless the rejection was a clerical error. It's more efficient to modify the name and resubmit.
Do I need a lawyer to register a company name?
No, but professional corporate secretaries (like Terra Advisory Services) can conduct thorough clearance searches, handle restricted-word referrals, and ensure you avoid expensive rebranding later.
