Differences Between RC, BN, IT, and LP Numbers in CAC Business Registration

‍

If you’ve ever tried to register a business in Nigeria, chances are you’ve come across a jumble of letters like RC, BN, IT, and LP—and wondered what they actually mean. These are not just random codes; they represent the legal backbone of your business identity in Nigeria. 

Choosing the wrong one can limit your business opportunities, affect your access to funding, or even expose you to legal risks. In this guide, we’ll break down what each CAC registration number stands for, how they differ, and how to choose the one that sets your business up for success.

‍

CAC and Business Registration in Nigeria

The Corporate Affairs Commission (CAC) is the official body responsible for regulating and managing the formation and operation of companies in Nigeria. Established by the Companies and Allied Matters Act (CAMA) in 1990, the CAC serves as the gatekeeper of Nigeria’s formal business environment, ensuring that entities comply with legal requirements for incorporation, operation, and governance.

The Commission also provides services such as business name searches, annual returns filing, and changes to company details.

‍

Why CAC Registration is Mandatory for Businesses in Nigeria

Registering with the CAC is not just a formality, it’s a legal requirement and a critical step toward legitimacy. Here's why:

• Legal Recognition: CAC registration gives your business legal identity, allowing it to operate as a recognized entity.
  
  
• Bank Account Opening: Most Nigerian banks require a CAC certificate before opening a corporate account.
  
  
• Access to Loans and Grants: Registered businesses can access funding from financial institutions, investors, and government programs.
  
  
• Brand Trust and Credibility: Customers and partners are more likely to trust a business that is officially registered.
  
  
• Tax Compliance and Structure: Registration links your business with a Tax Identification Number (TIN), making compliance with FIRS and state tax authorities easier.

Failure to register can result in penalties, limited business opportunities, and ineligibility for public tenders or funding.

‍

Types of Business Entities Recognized by CAC

The CAC recognizes several forms of business structures, each with distinct registration numbers and implications for taxation, liability, and management. Understanding these entities helps in choosing the right registration path.

1. Sole Proprietorship:

A Sole Proprietorship is the simplest and most common business structure in Nigeria. It is owned and operated by one individual and registered under a BN (Business Name). It has no separate legal identity from the owner, meaning the owner is personally liable for the business’s debts and obligations

‍Example: A local fashion designer operating under “BN 987654 – Tolu’s Couture.”

‍

2. Partnership

A Partnership involves two or more people who run a business together under a BN registration. While informal partnerships can exist, registering formalizes the relationship and helps define the roles and liabilities of each partner.

Example: A law firm registered as “BN 123789 – Ade & Kunle Legal Practitioners.”

‍

3. Limited Liability Company (LLC)

A Limited Liability Company, registered under an RC (Registered Company) number, is a separate legal entity. This means the company is distinct from its shareholders and directors, limiting personal liability. LLCs are the most common corporate structure for SMEs and larger enterprises in Nigeria.

Example: “RC 456789 – Infinity Technologies Ltd.”

‍

4. Incorporated Trustees

An Incorporated Trustee structure is designated for non-profits, such as NGOs, religious organizations, clubs, and charitable foundations. Registered under an IT (Incorporated Trustees) number, this structure ensures the organization operates as a legal entity without the intent of profit-making.

Example: “IT 112233 – Women for Health Foundation.”

‍

5. Limited Partnerships

A Limited Partnership (LP) or Limited Liability Partnership (LLP) is a hybrid structure that combines features of partnerships and corporations. One partner must have unlimited liability (general partner), while others have limited liability (limited partners). These are registered under an LP number.

Example: “LP 334455 – PrimeTech Ventures LP,” used by a startup incubator fund.

‍

Key Differences Between RC, BN, IT, and LP Numbers

‍

Legal Personality and Liability Comparison

• RC (Limited Liability Company): The company is a distinct legal entity. Shareholders have limited liability, meaning their personal assets are protected from business debts.
  
  
• BN (Business Name): The business is not separate from the owner. The owner has full personal liability for debts and obligations.
  
  
• IT (Incorporated Trustees): A separate legal entity for non-profit purposes. Trustees are not personally liable as long as they act within their legal duties.
  
  
• LP/LLP:
  
  
  • In LPs, general partners have unlimited liability, while limited partners are only liable up to their investment.
    
    
  • In LLPs, all partners enjoy limited liability, similar to an RC.
    
    

Taxation Implications

• RC: Subject to Company Income Tax (CIT), Value Added Tax (VAT), and must register with FIRS. Also eligible for tax incentives and reliefs.
  
  
• BN: Taxed under Personal Income Tax (PIT) as the income of the sole proprietor or partners. Must obtain a Tax Identification Number (TIN).
  
  
• IT: Generally tax-exempt if operated strictly for charitable purposes, but still required to register for TIN and may file returns if it engages in revenue-generating activities.
  
  
• LP/LLP:
  
  
  • LP: Partners are taxed based on their profit share (Personal Income Tax).
    
    
  • LLP: Treated like companies; subject to Company Income Tax.
    
    

Banking and Financial Recognition

• RC: Widely recognized by banks, regulatory bodies, and financial institutions. Required for corporate loans, investment registration, and equity financing.
  
  
• BN: Suitable for basic banking services and POS merchant onboarding, but may not qualify for large-scale funding.
  
  
• IT: Required for opening NGO bank accounts. Increases credibility for grant applications and international partnerships.
  
  
• LP: Used in investment banking, fund management, and capital raising. Often needed for VC fund structures or professional partnerships.
  
  

Operational Scope and Regulatory Obligations

• RC:
  
  
  • Required to file annual returns, hold AGMs, and maintain corporate governance structures.
    
    
  • Must register any changes (e.g., directors, shareholding).
    
    

• BN:
  
  
  • Simpler compliance. Must renew registration periodically and file annual returns, but has minimal governance requirements.
    ‍
    

• IT:
  
  
  • Must file annual financial reports, trustee changes, and meeting resolutions.
    
    
  • Monitored to ensure activities align with its charitable objectives.
    
    

• LP/LLP:
  
  
  • LPs must disclose partnership changes and file returns annually.
    
    
  • LLPs must maintain records, file tax returns, and adhere to governance standards similar to RCs.

‍

RC Number (Registered Company Number)

‍

An RC Number, short for Registered Company Number, is the unique identification number assigned to limited liability companies (LLCs) registered with the Corporate Affairs Commission (CAC) in Nigeria. The RC number signifies that the business is a corporate legal entity distinct from its owners, with rights and responsibilities under Nigerian law.

An RC number confers corporate status, which includes limited liability protection, perpetual succession, and the ability to own property, enter contracts, and sue or be sued in the company’s name.

‍

Entity Type: Limited Liability Company (LLC)

The RC number is exclusively issued to Limited Liability Companies in Nigeria, which can be categorized as:

• Private Limited Company (Ltd) – Common among SMEs and startups.
  
  
• Public Limited Company (Plc) – For larger corporations intending to raise capital through public shares.
  
  
• Companies Limited by Guarantee – Often used for non-profits operating commercially without shareholders.

LLCs are the most robust legal structures for business in Nigeria due to their separation of ownership and control, scalability, and credibility.

‍

Format and Example

RC numbers follow a numeric format preceded by the letters “RC”, with no special characters or spacing in the digits. The numbers are assigned sequentially and can vary in length depending on registration volume.

Example: RC 123456 – ABC Global Enterprises Ltd.

• RC: Indicates the company is registered under the “Registered Company” category.
  
  
• 123456: The unique identifier.
  
  
• ABC Global Enterprises Ltd.: An example of a limited liability company.

This RC number appears on the company’s Certificate of Incorporation, all official documents, invoices, and regulatory filings.

‍

Use Cases of RC Numbers in Legal and Financial Transactions

The RC number is foundational to a wide range of legal, financial, and regulatory transactions, including:

• Opening a Corporate Bank Account: Nigerian banks require an RC number to validate incorporation before account setup.
  
  
• Applying for Loans and Grants: Financial institutions verify the RC number during due diligence.
  
  
• Filing Annual Returns with CAC: Required for legal compliance and renewal of company status.
  
  
• Filing Taxes with FIRS: An RC number is needed when obtaining a Tax Identification Number (TIN) and filing Company Income Tax (CIT).
  
  
• Entering Contracts: Clients and vendors verify RC numbers to confirm legitimacy before signing contracts.
  
  
• Government Bidding and Procurement: Federal and state agencies require valid RC numbers as part of pre-qualification.

‍

‍

BN Number (Business Name Number)

A BN Number, short for Business Name Number, is the unique identification number assigned to sole proprietorships and partnerships registered with the Corporate Affairs Commission (CAC) in Nigeria. It represents the most basic form of business registration, offering legitimacy without the complexities of forming a separate legal entity.

BN numbers provide entrepreneurs with an official business identity recognized by financial institutions, government agencies, and customers, while still tying the business directly to the individual(s) who own it.

‍

Entity Type: Sole Proprietorship or Partnership

BN numbers are issued to two primary types of informal business structures:

• Sole Proprietorship: A business owned and operated by a single individual, with no legal distinction between the owner and the business. The owner is personally liable for debts and obligations.
  
  
• Partnership: A business operated by two or more individuals who share profits, liabilities, and responsibilities. Like sole proprietorships, partnerships are not separate legal entities from their owners.

These structures are popular among artisans, freelancers, small retail businesses, and service providers due to their low setup costs and minimal administrative requirements.

‍

Format and Example

BN numbers are numeric and are always preceded by the letters “BN”, followed by a sequential identification number.

Example: BN 876543 – John's Electronics

• BN: Denotes Business Name registration.
  
  
• 876543: Unique identifier in the CAC registry.
  
  
• John’s Electronics: An example of a small electronics retail business.

The BN number appears on the Certificate of Registration and is used in various official transactions and verifications.

‍

Use Cases of BN Numbers for Informal Businesses and Startups

While BN registration does not confer separate legal identity or limited liability, it serves as a vital stepping stone for informal businesses and startups seeking to operate formally:

• Opening a Business Bank Account: Most banks allow sole proprietors and partnerships to open accounts using a BN number.
  
  
• Brand Legitimacy: Displaying a BN number on invoices, receipts, and signage boosts customer trust.
  
  
• Participation in Government and Private Tenders: Many grant programs and vendor portals require proof of registration.
  
  
• Tax Compliance: A BN number allows registration with the Federal Inland Revenue Service (FIRS) for a Tax Identification Number (TIN).
  
  
• Digital Platform Registration: Online marketplaces and payment platforms often require CAC registration before onboarding a vendor.

BN numbers are particularly useful for entrepreneurs who want to test a business idea before committing to a more complex legal structure.

‍

‍

IT Number (Incorporated Trustees Number)

An IT Number, or Incorporated Trustees Number, is a unique registration code assigned by the Corporate Affairs Commission (CAC) to non-profit organizations operating in Nigeria. This includes religious organizations, NGOs, community-based associations, clubs, and foundations that are not established for the purpose of making profit.

The IT number confirms that an organization has legal standing as an incorporated entity under Part F of the Companies and Allied Matters Act (CAMA), empowering it to own property, enter contracts, and operate in its own name.

‍

Entity Type: NGOs, Religious Bodies, Clubs, Foundations

The IT number is specifically issued to the following types of non-commercial entities:

• Non-Governmental Organizations (NGOs): Advocacy groups, social welfare groups, and international development organizations.
  
  
• Religious Bodies: Churches, mosques, and other faith-based entities.
  
  
• Clubs and Associations: Social clubs, alumni groups, and community development associations.
  
  
• Foundations and Charities: Organizations set up to provide humanitarian aid, scholarships, healthcare, or environmental support.

Unlike business names and companies, incorporated trustees are governed by a board of trustees rather than owners or shareholders. All profits must be reinvested into the organization’s mission.

‍

Format and Example

IT numbers are issued in numeric format, always prefixed with “IT,” followed by a unique sequential number.

Example: IT 135792 – Green Earth Foundation

• IT: Indicates the organization is registered as an Incorporated Trustee.
  
  
• 135792: Unique identifier issued by the CAC.
  
  
• Green Earth Foundation: An environmental NGO focused on reforestation in Nigeria.

The IT number appears on the Certificate of Incorporation of Trustees and is used in all official documentation and filings.

‍

Use Cases in Charitable and Not-for-Profit Activities

The IT number is essential for nonprofits seeking legal recognition, donor trust, and operational legitimacy. Common use cases include:

• Opening Organizational Bank Accounts: Banks require an IT number to open non-profit or foundation accounts.
  
  
• Donor Verification: Both local and international donors confirm CAC registration via the IT number to ensure transparency.
  
  
• Eligibility for Grants and Funding: Most donors and foundations, including foreign aid bodies, require proof of IT registration.
  
  
• Property Ownership: Incorporated trustees can acquire land and property in the organization’s name.
  
  
• Regulatory Compliance: Required for filing annual returns, financial reports, and compliance with the Federal Inland Revenue Service (FIRS).
  
  
• Public Credibility: NGOs with IT numbers are more likely to be perceived as legitimate, organized, and transparent.

‍

‍

LP Number (Limited Partnership Number)

An LP Number, or Limited Partnership Number, is the unique identification number assigned by the Corporate Affairs Commission (CAC) to businesses registered as Limited Partnerships (LP) or Limited Liability Partnerships (LLP) in Nigeria. This number officially recognizes the business as a hybrid legal structure that combines elements of partnership and corporate governance.

LP registration is ideal for ventures where flexibility, shared management, and risk protection are essential, especially in sectors like investment, startups, and professional services.

‍

Entity Type: Limited Partnership or Limited Liability Partnership (LLP)

The LP number applies to two main forms of partnership entities:

• Limited Partnership (LP): A business structure with at least one general partner and one limited partner. General partners manage the business and are fully liable for its debts, while limited partners contribute capital but have limited liability and minimal control.
  
  
• Limited Liability Partnership (LLP): A more modern structure where all partners have limited liability, but unlike LPs, LLPs enjoy a corporate-style governance model. LLPs are often used by law firms, consulting groups, and joint ventures.

These entities are registered under Part C of CAMA 2020, offering more formal recognition and legal benefits compared to informal partnerships.

‍

Format and Example

LP numbers are sequential numeric identifiers prefixed by the letters “LP.”

Example: LP 246810 – NextGen Creatives LP

• LP: Denotes registration as a Limited Partnership.
  
  
• 246810: Unique registration number issued by CAC.
  
  
• NextGen Creatives LP: An example of a creative industry incubator structured as a limited partnership.

The LP number appears on the Certificate of Registration, and is used in official filings, contracts, and banking transactions.

‍

Legal Structure: Roles of General and Limited Partners

A Limited Partnership includes at least:

• One General Partner: Responsible for managing the business and assumes unlimited liability for its debts and obligations.
  
  
• One Limited Partner: Contributes capital but does not engage in daily operations, and has liability limited to the extent of their investment.

This structure allows investors to participate in business ventures without taking on operational risk, while founders or operators maintain control.

In an LLP, all partners share management roles but still benefit from limited personal liability, an attractive option for professionals and co-founders.

‍

Use Cases in Investment, Tech Incubators, and Venture Capital

LP and LLP structures are increasingly used in sectors where capital pooling, risk management, and flexible governance are essential:

• Venture Capital Funds: LPs are the preferred legal structure for VC firms where fund managers are general partners and investors are limited partners.
  
  
• Startup Accelerators and Incubators: These entities use LP structures to manage shared equity and investment pools for portfolio startups.
  
  
• Professional Firms: LLPs are common among law firms, architectural firms, and accounting groups for risk-sharing and management efficiency.
  
  
• Real Estate Investment Groups: LPs allow passive investors to fund property development while entrusting operations to experienced developers.

The LP number ensures these partnerships operate within the bounds of Nigerian law, providing a framework for dispute resolution, compliance, and external partnerships.

FAQs

Can a business have more than one CAC number?

No, each registered entity under the Corporate Affairs Commission (CAC) is assigned one unique registration number. However, a single individual can register multiple businesses, each with its own CAC number (e.g., BN, RC, or IT) depending on the structure chosen. For example, you can operate a BN and later incorporate a separate RC—each will have distinct numbers.

‍

Can I convert a BN to RC later?

Yes, you can upgrade a Business Name (BN) to a Registered Company (RC). This involves incorporating a new Limited Liability Company and transferring assets, clients, or goodwill from the BN to the RC. While the BN cannot be directly converted, you can use a similar name (if available) and inform stakeholders of the transition to formal incorporation.

‍

How do I update business information tied to my CAC number?

You can update your business information, such as address, directors, business objectives, or shareholding, by filing the appropriate post-incorporation documents on the CAC portal. Examples include:

• Form CAC 7A for director changes
  
  
• Form CAC 2A for share updates
  
  
• Form CAC 3 for address changes
  Supporting documents and official fees apply, and updates must be filed promptly to remain compliant.

‍

Are CAC numbers linked to TIN (Tax Identification Number)?

Not automatically, but they are related. After CAC registration, you must apply separately for a TIN with the Federal Inland Revenue Service (FIRS). FIRS will reference your CAC number during this process. Some integrated systems may now facilitate automatic TIN generation for RCs, but verification and follow-up are still advised.

‍

What happens if I operate without a CAC number?

Operating without a CAC registration means your business is not legally recognized. This can result in:

• Ineligibility for bank accounts, loans, grants, or tenders
  
  
• Difficulty securing partnerships or contracts
  
  
• Legal penalties, especially for larger or public-facing businesses
  
  
• Loss of credibility with customers, investors, and regulators

Registering with CAC protects your brand, grants legitimacy, and opens doors to formal opportunities.
