Say you bake and sell cakes from your kitchen in Ibadan, and a hotel wants to place a regular order. Their finance team asks for an invoice from a registered business and a corporate account to pay into. A personal Instagram page won't satisfy them. This is the moment most small traders start looking at the Corporate Affairs Commission (CAC).
This guide explains how business name registration works, how to prepare so you don't get rejected, and when a business name is the wrong choice. I'm deliberately not quoting fees, processing times or form numbers, because those change. Confirm them on the official CAC website, cac.gov.ng, before you pay anything.
What a registered business name is (and isn't)
A business name is the simplest form of registration in Nigeria. It suits a sole owner or a small partnership trading under a name other than their own. Legally, you and the business are the same person. If the business owes money, your personal assets can be pursued.
A limited liability company is different. It is a separate legal entity, with directors and shareholders, and it has more filing duties. If you only need to open a business account, issue invoices and look credible, a business name is usually enough to start.
Business name or limited company: how to choose
| Question | Business name | Limited company |
|---|---|---|
| Who owns it? | One person or a few partners | Shareholders, run by directors |
| Personal liability | Owner is personally liable | Generally limited to the company's share capital |
| Admin load | Lighter | Heavier, with more compliance duties |
| Raising investment | Hard | Easier, shares can be issued |
| Best for | Shops, freelancers, caterers, tailors, small traders | Growing firms, those seeking investors, bigger contracts |
If you plan to bid for large corporate or government contracts, or bring in investors, ask an accredited adviser whether to go straight to a company. Starting with a business name and upgrading later is common, but check what your target clients require.
Before you start: what to prepare
Requirements can be updated, so treat this as a checklist of what is normally asked, then compare it with the current CAC list.
- Two or three name options. Your first choice may already be taken or be too close to an existing one.
- A clear description of what the business does. Be specific, such as "bakery and catering", not "general business".
- Your full personal details. These must match your identity documents exactly, including spelling and order of names.
- A valid government ID and your NIN. Check which ones CAC currently accepts.
- A business address. This should be a real, reachable address where you can receive correspondence.
- An active email address and phone number. Use ones you control, since approvals and queries go there.
- A passport photograph and signature, in the format the portal asks for.
If your NIN record has a spelling or date-of-birth mismatch, fix it first. A mismatch is a common reason applications stall across many Nigerian systems.
Step-by-step: registering
- Go only to the official site. Type the CAC address yourself. Don't click links from social media ads or WhatsApp messages.
- Create or log in to your account. Use your own email, not an agent's.
- Run a name availability search. Search each of your options. Avoid names that are nearly identical to well-known brands, since CAC can reject names that are the same or misleadingly similar to an existing one.
- Reserve the name if the portal offers it. Note any validity window for the reservation, and confirm it on the portal.
- Fill in the application. Enter proprietor details, business address, nature of business and commencement date.
- Upload documents. Make sure scans are clear and readable, not cropped phone photos with a shadow across them.
- Pay the official fee through the portal's payment page. Keep the receipt. Never pay into a personal account for "CAC processing".
- Wait for review and watch your email. If CAC queries something, respond quickly and exactly as asked.
- Download and save your certificate. Store copies on your phone, email and a flash drive.
A worked example: choosing a name (hypothetical)
Amaka wants to register her cake business. Her options are "Amaka's Cakes", "Sweet Crown Bakes" and "Royal Crown Cakes Nigeria".
- "Amaka's Cakes" is plain and likely common. The search returns several similar names, so it is risky.
- "Royal Crown Cakes Nigeria" looks too close to bigger brands with "Crown" in the name. She drops it.
- "Sweet Crown Bakes" returns nothing close. She reserves it and describes the business as "baking and catering services".
The lesson: test several names, avoid copying famous brands, and choose something you can also use as a handle on social media. Check that the handle and any domain are free before you commit.
Common mistakes and how to avoid them
Paying a random "agent" up front
Some accredited professionals do help with filing, and that's legitimate. But fake agents exist, and they collect money then vanish or hand over forged certificates. Ask for their accreditation, confirm it with CAC, pay into a verifiable business account, and make sure the application is in your name with your email. The same checks in our guide to fake agents apply here.
Using a vague or misleading business description
A description that doesn't match what you actually sell can cause trouble when a bank or client reviews your documents. Describe your real activity. If you later add a major new activity, ask CAC how to update your records.
Mismatched names across documents
If your ID says "Chukwuemeka Obi" and the form says "Emeka Obi", expect questions. Use the legal name everywhere.
Forgetting life after the certificate
Registration isn't the end. You may need a tax identification number, and your bank will have its own account opening checks. Rules on who levies which taxes differ between federal and state levels, which our explainer on federal, state and local government covers in general terms. Confirm tax duties with the relevant tax authority or a qualified accountant.
Ignoring annual filing duties
Registered businesses can have ongoing obligations, such as periodic returns. Missing them can bring penalties or put your registration at risk. Ask CAC what applies to your type of registration and when.
How the advice changes for different people
- Freelancers and online earners: A business name can help you open a business account for receiving payments and issue proper invoices. Check with your bank what they require, and keep personal and business money apart.
- Two or more partners: Write down who contributes what and how profit is shared before you register. A signed agreement avoids fights later.
- Students and corps members: You can usually register while studying or serving, but your ID and NIN details must be current. Read the programme rules if you are in NYSC, and see what to sort before you register for NYSC.
- Nigerians abroad: Residency and local-presence rules can differ. Ask CAC or a licensed Nigerian adviser before filing, and don't hand your NIN or ID to a third party you can't verify.
- Readers outside Nigeria: Ghana, Kenya and South Africa each have their own registries and rules. This guide covers Nigeria only.
Frequently asked questions
Do I need a registered name to start selling?
Not to begin. Many people start informally to test demand. You need registration when you want corporate clients, a business bank account, or to apply for formal support and contracts.
Can two businesses have the same name?
The name search exists to stop that. Names that are identical or too similar to existing ones can be rejected, so check several options.
How long does it take and how much does it cost?
I don't have current official figures, and they change. Check the CAC portal for the fee schedule and expected timelines, and be suspicious of anyone quoting a very different price.
Can I register a name and change it later?
Changes are possible through CAC's process, but it involves another application. It is cheaper to choose carefully the first time.
Is a business name the same as a trademark?
No. Registering a business name doesn't automatically protect your brand as a trademark. Trademarks are handled separately, so ask a licensed practitioner if your brand matters to you.
Your next step
Tonight, write down three name options, check your NIN details match your ID, and run each name through the search on the official CAC site. Only pay once you've seen the fee on the portal itself.
Fees, dates, requirements and procedures change. Always confirm with the official agency or institution before you act.
