How to Register a Business Name with CAC in Nigeria (2026 Step-by-Step Guide)

Registering a business name with the Corporate Affairs Commission (CAC) in Nigeria costs between ₦10,000 and ₦15,000 in official fees and takes 24–72 hours after successful submission on the ICRP portal. The process is fully online — no physical CAC office visit required. You need a valid government-issued ID (National ID, International Passport, or Driver's Licence), a passport photograph, your proposed business name, and your business address. Most rejections happen at the name search stage or during document upload — both are avoidable with the right preparation.

This guide was written by Elu Buduka Emmanuel, fullstack developer and founder of Budutech Digital Services Limited — a technology and business registration company based in Port Harcourt, Rivers State. Budutech has processed CAC registrations for entrepreneurs across Nigeria, from solo traders in Aba to startups in Lagos and Abuja. The patterns that cause rejections, delays, and errors are the same everywhere. This guide addresses all of them.

Quick Context

• Problem: The CAC ICRP portal has a steep learning curve and no real error messaging — applicants don't know why they failed
• Who it affects: First-time business owners, freelancers formalizing their services, and entrepreneurs opening bank accounts
• Why existing tutorials fail: They cover the happy path. They skip portal errors, document rejection, and name conflicts
• What this delivers: End-to-end registration with zero guesswork — from name search to certificate download
• Nigerian constraint: Unstable internet and portal timeouts are real. This guide accounts for them.

System Breakdown

What Is CAC Business Name Registration?

CAC Business Name Registration is the legal process of registering a sole proprietorship or partnership under Nigeria's Companies and Allied Matters Act (CAMA) 2020. The Corporate Affairs Commission is the federal body that manages this process.

A registered business name gives you a BN number — a unique identifier that proves your business exists legally in Nigeria. It's different from an RC number, which is for limited liability companies. If you're a solo operator or a small partnership, BN registration is what you need. If you want to raise equity, limit personal liability, or onboard co-founders with formal structure, you register a company (RC number) instead.

Banks in Nigeria require either a BN or RC number before opening a business current account. Most grant applications, government contracts, and B2B invoicing situations require one too.

How Much Does CAC Business Name Registration Cost in Nigeria?

CAC business name registration costs approximately ₦10,500 in total government fees — broken into a ₦500 name reservation fee and a ₦10,000 filing fee paid through Remita. These are the official CAC charges as of 2026.

If you use an accredited CAC agent or registration service, expect to pay an additional service fee of ₦5,000–₦20,000 on top of government fees, depending on who handles it. Budutech Digital Services registers business names for clients across Nigeria for a flat, transparent fee — no surprises.

There are no state-specific CAC levies. However, after registration, some states — including Lagos and Rivers State — require separate business premises registration or trade permit fees at the local government level. These are not CAC fees.

Fee summary:

• Name reservation: ₦500
• Business name filing: ₦10,000
• Total government fees: ₦10,500
• Agent service fee (if applicable): ₦5,000–₦20,000
• Estimated total (DIY): ₦10,500–₦15,000 including transaction charges

What Documents Do You Need for CAC Business Name Registration?

You need five items to complete CAC business name registration: a valid government-issued ID, a passport photograph, your NIN (National Identification Number), your proposed business name, and your business address within Nigeria.

Full document list:

1. Valid government-issued ID — National ID card (NIN slip not accepted), International Passport, or Driver's Licence. Must be unexpired.
2. Passport photograph — Clear, recent, white background. JPEG format, under 500KB.
3. NIN — Your 11-digit National Identification Number. Linked to your identity on the ICRP portal.
4. Proposed business name — Up to 3 alternatives in order of preference.
5. Business address — A physical address in Nigeria. A residential address works for business name registration.

For partnerships (two or more proprietors), each partner must provide their own ID, photograph, and NIN.

How to Do a CAC Name Search Before Registration

The CAC name search is the first step and the most skipped — which is why so many applications get rejected.

The public name search is free and requires no login. Go to icrp.cac.gov.ng, click "Public Search", and enter your proposed business name. The system will return any existing registered entity that matches or closely resembles your name.

What makes a name unavailable:

• Exact match with an existing registration
• Too similar to an existing name (e.g., "Dangote Foods" vs "Dangote Food" — both flag)
• Contains restricted words: "Federal," "National," "Government," "Bank," "Insurance," "Trust," "Group" without prior approval
• Contains a name that implies foreign government connection

Pro tip: Search your name in multiple formats. If you want "Greenlight Solutions," also search "Greenlight," "Green Light Solutions," and "Green-Light." The ICRP search does partial matching. If any variation is registered in a similar sector, CAC may reject yours.

Have at least three name alternatives ready before you begin the registration process. The ICRP portal lets you enter up to three names in order of preference during application.

How to Register a Business Name with CAC on the ICRP Portal — Step by Step

Step 1 — Create Your ICRP Account Go to icrp.cac.gov.ng and click "Register" to create a new account. Enter your email address, phone number, and NIN. You'll receive an OTP to verify your email. Once verified, log in with your credentials. If the OTP doesn't arrive within 5 minutes, check spam — or use a different email address (Gmail works most reliably on the portal).

Step 2 — Start a New Application From your dashboard, click "Pre-Registration" then select "Business Name" from the entity type options. The portal will prompt you to begin a new filing.

Step 3 — Enter Your Business Name Preferences Enter your first-choice business name, then your second and third alternatives. The system checks availability in real time. If your name is available, you'll be prompted to proceed. If it's taken, select your next alternative. Names are not reserved until payment is made.

Step 4 — Fill in the Proprietor Information Enter your personal details: full legal name (exactly as it appears on your ID), date of birth, NIN, phone number, and residential address. For partnerships, repeat this for each proprietor. The system will flag mismatches between your NIN and the name you entered — make sure they match exactly.

Step 5 — Enter Business Details Enter your business address (must be a Nigerian address), business nature/description (what the business does), and your proposed commencement date. Be specific about business nature — "general merchandise" is less likely to cause issues than niche descriptions in regulated sectors like finance or medicine.

Step 6 — Upload Documents Upload your passport photograph and ID document. Files must be JPEG or PDF, and each must be under 500KB. If your file is too large, compress it at ilovepdf.com or smallpdf.com before uploading. The portal will reject files exceeding the size limit without a clear error message — if your upload seems to hang, the file size is usually the problem.

Step 7 — Pay the Filing Fee Once all details are complete, the portal generates a payment invoice. Pay through Remita using your debit card, internet banking, or USSD. Keep your Remita receipt number — you'll need it if there are any payment verification issues. After successful payment, the portal confirms your submission and returns a tracking reference number.

Step 8 — Track and Download Your Certificate Log in to your ICRP dashboard and check your application status. Processing typically takes 24–72 hours. When approved, your certificate appears in your dashboard as a downloadable PDF with an embedded QR code for verification. Download and save it immediately. This is your official CAC Business Name certificate.

Why Does the CAC Portal Reject Applications — and How Do You Fix It?

The ICRP portal doesn't always give clear rejection messages. Most rejections fall into four categories.

Name conflict — Your proposed name is too similar to an existing one. Fix: run a thorough name search before applying, not during. Have three solid alternatives ready.

NIN mismatch — The name you entered doesn't match what's on your NIN record. Fix: check your NIN details on the NIMC portal (nimc.gov.ng) before filling the form. Use your name exactly as NIMC has it.

Document quality — Blurry ID photos, low-contrast images, or non-matching photos get flagged. Fix: use a clear, well-lit photo taken directly on a plain white wall. Compress it but don't distort it.

Expired ID — The portal flags expired identification documents. Fix: use an unexpired ID. If your NIN card has expired, use your International Passport or Driver's Licence instead — or update your NIN card first at any NIMC office.

If your application is rejected, the status updates to "Rejected" in your dashboard. You can resubmit without paying the name reservation fee again, but you'll pay the filing fee a second time. Getting it right on the first attempt saves ₦10,000.

The Budutech Registration Stack — A 3-Phase Approach to Clean CAC Registration

The Budutech Registration Stack is the structured approach Budutech Digital Services Limited uses when handling CAC registrations for clients across Nigeria. It reduces rejections to near zero.

Phase 1 — Intelligence (before you touch the portal)

1. Run a deep name search across the ICRP public database and Google
2. Verify all proprietor NIN details on the NIMC portal
3. Prepare and compress all documents to spec before logging in
4. Select a business description that doesn't trigger regulated-sector flags

Phase 2 — Registration (portal execution)

1. Create the account with a stable internet connection (avoid mobile data on the first session)
2. Complete all form fields in one session — the portal has session timeout issues
3. Upload pre-verified documents in the correct format
4. Pay immediately after form completion — don't leave the payment screen

Phase 3 — Comply (post-registration)

1. Download and back up the certificate the moment it's approved
2. Apply for TIN at tin.jtb.gov.ng using your BN number
3. Open a business current account using your certificate and TIN
4. Register on the FIRS platform for tax compliance

This framework reduces the average registration time from 5–7 days (with errors and resubmissions) to 24–72 hours.

What Happens After CAC Business Name Registration?

After you receive your BN certificate, three things need to happen immediately.

Get your TIN. Your Tax Identification Number is issued free by the Joint Tax Board at tin.jtb.gov.ng. Use your BN number to apply. Most banks now require a TIN alongside your CAC certificate before opening a business account.

Open a business current account. Take your CAC certificate, TIN, valid ID, and passport photographs to any commercial bank in Nigeria. First Bank, GTBank, Zenith, Access, and UBA all process business current accounts. Some banks (like GTBank and Zenith) allow you to initiate the process online.

Get your local business permit. In cities like Lagos, Abuja, and Port Harcourt, local government councils require a separate business premises permit or trade permit. This is not a CAC requirement — it's an LGA-level requirement. Check with your specific LGA office for their current requirements.

Frequently Asked Questions

How long does CAC business name registration take in Nigeria? CAC business name registration takes 24–72 hours after successful submission and payment on the ICRP portal. If your documents are clean and your name is available, most applications are approved within one business day. Delays beyond 72 hours usually indicate a review flag — log in to your ICRP dashboard to check your application status.

Can I register a business name with CAC without a lawyer or agent? Yes. The ICRP portal is designed for self-registration. You don't need a lawyer or CAC agent to register a business name. However, if you've had a previous rejection, your documents are complex, or you simply don't have time to manage the portal process, a registered agent like Budutech Digital Services handles it faster with a significantly lower rejection rate.

What is the difference between a BN number and an RC number? A BN number (Business Name number) is assigned to registered sole proprietorships and partnerships — businesses with one or more individual owners who have unlimited personal liability. An RC number (Registration of Companies number) is assigned to incorporated companies — limited liability companies (LTD) or public companies (PLC). If you're a solo freelancer or trader, you register a business name (BN). If you want limited liability and a board structure, you incorporate a company (RC).

How much does CAC business name registration cost in Nigeria in 2026? The official CAC fees for business name registration in 2026 are ₦500 for name reservation and ₦10,000 for the filing fee — a total of ₦10,500 in government charges. Additional bank transaction fees from Remita typically add ₦100–₦500. If you use a registration agent, their service fee is separate and typically ranges from ₦5,000 to ₦20,000.

Can I register a business name with CAC from outside Nigeria? Yes, you can complete the ICRP portal process from abroad, but you must have a valid Nigerian ID (NIN-linked), a Nigerian phone number, and a Nigerian business address. Payment must be made through Remita, which accepts Nigerian debit cards. If you don't have active Nigerian banking, the process becomes difficult — in that case, authorizing a trusted local agent is the practical solution.

What happens if my preferred business name is taken? If your preferred name is already registered or too similar to an existing one, the ICRP portal will reject it during the name search phase. You'll need to enter an alternative name. You're allowed up to three name preferences per application. If all three are rejected, you must start a new application with different names — no additional name reservation fee applies until you proceed to payment again.
