- ACRA charges a non-refundable S$15 per name application, so search Bizfile thoroughly before applying to avoid duplicate fees.
- Words like “bank,” “university,” and “insurance” require extra agency approvals, which can extend timelines from hours to up to 60 days.
- ACRA registration only secures your legal entity name. Trademark separately with IPOS for brand protection.
- Your legal name and trading name can differ, as long as your legal name and UEN appear on official documents.
Choosing a company name in Singapore sounds simple until you realise that the wrong name can get your application rejected outright, delay your incorporation by weeks, or expose you to a passing-off lawsuit. Most founders spend hours debating words and aesthetics without first checking whether the name is even registrable. ACRA has clear rules on what is allowed, and the gaps in that knowledge are surprisingly costly. Setting up a company is a challenge, but thinking of a company/brand name can be more challenging. The name you choose will be the name that your customers will identify you with, so it should define the image you want to portray.
Before you fall in love with a name, here is exactly what ACRA requires, what triggers a referral delay, and what founders in 2026 most commonly overlook.
Why your company name matters more than you think
Your company name is the first impression on every contract, invoice, and investor deck. It is also the first filter your incorporation application has to pass. ACRA, the Accounting and Corporate Regulatory Authority, reviews every proposed name before you can incorporate, and rejections are not uncommon. Getting it right the first time saves you the S$15 re-application fee, but more importantly, it saves you the momentum you lose while waiting.
The ACRA rules: What is and is not allowed
1. No obscene or undesirable names
Under Section 27(1) of the Companies Act, ACRA will reject any name it considers undesirable. That includes names with obscene words, names that could mislead the public, and names that contain religious terms used without proper context. When in doubt, err on the side of neutral and professional.
2. Certain words trigger regulatory review
Some words trigger an automatic referral to another government agency before your name is approved. This extends your processing time from the usual few hours to anywhere between 14 and 60 days.
Words that commonly trigger referrals include:
- “Academy,” “Education,” “School,” “University” — referred to the Ministry of Education
- “Bank,” “Finance,” “Insurance” — referred to the Monetary Authority of Singapore (MAS)
- “Law,” “Legal,” “Chambers” — referred to the Ministry of Law
- “Media,” “Broadcasting” — referred to the Infocomm Media Development Authority (IMDA)
- “ASEAN,” “National,” “Singapore” — may require supporting documentation or justification
You can find the full list of Referral Authorities on ACRA’s website.
3. Your name must be unique
ACRA will not approve a name that is identical to any existing registered, active, or reserved business name. “Identical” is defined more broadly than you might expect. When assessing similarity, ACRA ignores:
- The word “The” at the start (so “The Alpha Tech Pte Ltd” and “Alpha Tech Pte Ltd” are considered the same)
- Legal suffixes like “Pte Ltd,” “Ltd,” or “LLP”
- Common trailing words such as “International,” “Singapore,” “Asia Pacific,” “Corporation,” or “.com”
- Plural vs singular forms
- Differences in spacing, punctuation, or letter case
This means “Alpha Tech” and “Alpha Technologies” might survive a name check, but “Alpha Tech” and “Alpha Tek” are likely to be flagged as too similar.
4. Name registration does not equal trademark protection
This is one of the most important points founders miss. Registering your company name with ACRA does not give you intellectual property rights over that name. Any competitor can register a similar name or trademark and use it commercially. If protecting your brand long-term matters to you, file a separate trademark application with the Intellectual Property Office of Singapore (IPOS). Domain names are also first-come, first-served. ACRA registration has no bearing on them.
How to check name availability on ACRA Bizfile
Before submitting your name application, run a thorough search on ACRA’s Bizfile portal. A name application costs S$15 and is non-refundable, so doing the groundwork first protects your money and your time.
Here is how to search effectively:
- Search the full name and common variations. If you want “Greenpath Solutions,” also search “Green Path,” “GreenPath,” “Green-Path,” and “Greenpath.”
- Search for phonetic equivalents. “Blu” and “Blue,” “Fynd” and “Find,” “Quik” and “Quick” — ACRA treats names that sound alike as potentially identical.
- Search for different word sequences. “Two Four Zero Technologies” and “Zero Two Four Technologies” could be considered the same.
- Search for synonyms. If your proposed name includes “Automobile,” check “Motor,” “Car,” and “Vehicle” as well.
Once you have confirmed availability on Bizfile, also check:
- The IPOS trademark database for potential IP conflicts
- Domain availability for your .com and .sg addresses
- LinkedIn company pages and social media handles
The name reservation process
When you submit a name application through Bizfile, the S$15 fee covers a reservation of up to 120 days. There are no extensions. If you do not complete your incorporation within that window, the name becomes available to others. You would need to reapply and pay the fee again.
If the name you want is currently reserved by someone else, you can wait it out. Reserved names lapse after 120 days if the holder does not proceed.
If a company with your preferred name has been dissolved or struck off, ACRA may allow you to use it upon appeal, though this is assessed on a case-by-case basis.
Registering a company name in Singapore as a foreign founder
The name application process is the same for everyone, but foreign founders have one critical difference: you cannot submit a name application on Bizfile independently. ACRA requires all foreigners to engage a Corporate Service Provider (CSP) to handle the submission on their behalf.
Beyond that, keep these points in mind before applying:
You need a local director before you can incorporate.
Your name can be approved and reserved, but you cannot complete incorporation without at least one Singapore-resident director: a Singapore citizen, Permanent Resident, or valid Employment Pass holder. If you do not have one, a nominee director service covers this requirement.
Your 120-day reservation clock starts immediately.
Once your name is approved, the countdown begins regardless of where you are in setting up your local director, registered address, or other incorporation requirements. Foreign founders often underestimate how quickly that window closes when coordinating across time zones.
Your name approval and your work visa are separate processes.
If you plan to relocate to Singapore to run your business, your Employment Pass application runs parallel to incorporation, not before it. Knowing this prevents founders from stalling on the name while waiting for visa clarity.
Avoiding the “passing off” risk
ACRA allows similar-but-not-identical names, but that does not mean using one is risk-free. The tort of passing off gives established brands the right to sue competitors whose names are close enough to cause customer confusion. Singapore courts have upheld passing-off claims even where the names were not technically identical.
The practical rule: if a reasonable customer could mistake your company for an existing one, you are exposed. This is especially true in the same industry or geographic market. A quick trademark search and a plain-language gut check go a long way.
Trading name vs legal name: You have flexibility
A common misconception is that the name on your incorporation documents is the only name you can use publicly. It is not. In Singapore, your legal company name and your trading name (or brand name) can be different.
For example, your legal entity might be registered as Riverstone Digital Holdings Pte Ltd, while you trade and market entirely as Riverstone. You do not need to file your trading name with ACRA, unlike in some other jurisdictions.
The requirement is disclosure, not uniformity. Under the Companies Act, your registered legal name and Unique Entity Number (UEN) must appear on all official business correspondence — including your website, contracts, invoices, and formal notices. Beyond that, your trading name can be whatever your brand calls for.
One important check: Verify that no competitor in your industry is already trading under your intended brand name, even if they have a different legal name. A trademark search on the IPOS database will surface any registered marks that could conflict.
Changing your company name after incorporation
Circumstances change. A pivot, a merger, a rebrand, all of them might prompt you to revisit your company name down the line.
The good news is that changing your company name in Singapore does not void existing contracts or obligations. As long as your UEN remains the same, all prior legal commitments remain intact and do not need to be renegotiated. You simply file a name change application through Bizfile and update your business materials once approved.
Practical checklist before you apply
Before submitting your name application on Bizfile, work through this list:
- Cleared the Bizfile availability search, including variations, phonetic equivalents, and synonyms
- Checked the IPOS trademark database for conflicting registered marks
- Confirmed domain availability for .com and .sg
- Verified social media handles are available on the platforms that matter to your business
- No regulated or referral-triggering words in the name (or you have budgeted for the extended wait time)
- No close resemblance to established brands in your industry that could attract a passing-off claim
- Trading name confirmed as distinct from any competitor already using it in your sector

FAQs on choosing a company name in Singapore
How do I check if a company name is available in Singapore?
Search on ACRA’s Bizfile portal. Enter your proposed name and also check variations in spelling, phonetic equivalents, and synonyms. Beyond ACRA, separately check the IPOS trademark database, your .com and .sg domain availability, and relevant social media handles. A clean result across all four gives you the strongest foundation before applying.
How long does ACRA take to approve a company name in Singapore?
Most standard applications are approved within a few hours on the same business day. However, if your name contains words that trigger a referral to another government agency, such as “bank,” “education,” or “insurance”, processing can extend to between 14 and 60 days. Factor this into your incorporation timeline before submitting.
What words are not allowed in a Singapore company name?
ACRA rejects names containing obscene language, misleading terms, or inappropriate religious references under Section 27(1) of the Companies Act. Beyond outright rejection, words like “university,” “finance,” “law,” and “media” trigger mandatory referrals to regulatory bodies, which significantly delay approval. Always review ACRA’s full list of referral-triggering words before finalising your name.
Does registering a company name in Singapore give me trademark rights?
No. ACRA registration and trademark protection are entirely separate. Registering your company name with ACRA does not give you exclusive rights over it. Any competitor can register a similar trademark and use it commercially. To protect your brand legally, file a separate trademark application with the Intellectual Property Office of Singapore (IPOS).
Can I change my company name after incorporation in Singapore?
Yes, you can apply to change your company name at any time through the Bizfile portal. Importantly, a name change does not affect your Unique Entity Number (UEN) or invalidate existing contracts and legal obligations; everything tied to your UEN remains intact. Once ACRA approves the change, update your business materials, website, and official correspondence accordingly.
