How to Find Your Company Registration Number in South Africa: 2026 Guide

To find your company registration number in South Africa, you can search the Companies and Intellectual Property Commission (CIPC) database using the BizPortal website, check your Cor14.3 registration certificate, or view your SARS eFiling profile. This unique identifier consists of the year of incorporation, followed by a six-digit sequence and a two-digit entity type code, such as 2026/123456/07.

What is a company registration number in South Africa?

A company registration number is a unique 13-digit identifier issued by the CIPC when a business is formally incorporated under the Companies Act. It serves as the official legal identity of your enterprise, distinguishing it from other entities and enabling you to open bank accounts, apply for credit, and register for tax.

In the South African context, this number is essential for transparency. Every private company (Proprietary Limited or PTY Ltd), non-profit, or state-owned enterprise must display this number on all official correspondence and business letters. Without this number, your business essentially does not exist in the eyes of the law or financial institutions.

Understanding the format of SA registration numbers

You might notice that your company registration number in South Africa follows a specific pattern. The first four digits represent the year your company was registered (e.g., 2026). This is followed by a forward slash, a unique six-digit serial number, and another slash followed by a two-digit code.

These two-digit codes indicate the entity type. Common codes include '07' for Private Companies (Pty Ltd), '08' for Non-Profit Companies (NPC), and '21' for incorporated professional practices like lawyers or auditors. Knowing this format helps you verify that a number provided by a supplier or contractor is legitimate.

How do you find your company registration number via CIPC?

The most direct way to find your company registration number in South Africa is through the CIPC’s official digital platform, BizPortal. By using the 'Enterprise Search' function, you can enter your company's registered name to retrieve its registration status, number, and director details instantly.

BizPortal was designed to streamline business services for South African entrepreneurs. To use it, simply visit the website and navigate to the search section. You do not always need to be logged in to perform a basic name search, making it the fastest route for lost numbers.

Using the CIPC e-Services portal

If the public search does not yield enough detail, you can log into the main CIPC e-Services portal. This requires a registered customer code and password. Once logged in, you can request an electronic disclosure or a free 'Short Standard Disclosure' which lists your registration number clearly.

This method is particularly useful if you need a formal document to prove your registration. The CIPC maintains the central registry for all South African businesses, so the information found here is the ultimate source of truth for your business’s legal standing.

How can you find your registration number on SARS eFiling?

If you have already registered for tax, your company registration number in South Africa is listed on your SARS eFiling dashboard under the 'Entity Development' or 'Registration Details' tabs. SARS links your Income Tax number directly to your CIPC registration number to ensure compliance.

Since March 2026, the integration between South African Revenue Service (SARS) and the CIPC has become even more seamless. When you register a company, the system automatically triggers a tax number application. Consequently, your SARS tax clearance status or 'Notice of Registration' (IT150) will always feature both your tax and CIPC numbers.

Finding the number on tax returns and certificates

Look at your most recent VAT201 or EMP201 submissions if you are registered for Value Added Tax or Pay-As-You-Earn (PAYE). Your registration number must be included in these filings. Similarly, your B-BBEE affidavit or certificate will prominently display this number as part of the entity identification process.

Where is the company registration number on official documents?

Your company registration number is located on the Cor14.3 certificate, which is the 'Notice of Incorporation' issued by the CIPC. It is also found on the first page of your Memorandum of Incorporation (MOI) and should be printed on every formal invoice or quote your business issues.

If you are a director, checking your old emails for the attachments sent by the CIPC or your formation agent when the company was first registered is a quick fix. Files usually named 'Registration Certificate' or 'Disclosure' will contain the digits you need.

Statutory requirements for displaying your number

According to the South African Companies Act, every company must mention its name and registration number in a legible characters on all business letters, notices, and other official publications. This includes digital formats like your website footer and email signatures.

Failure to display your company registration number in South Africa can lead to administrative fines. It is a vital part of your 'business stationery' and should be easily accessible to your administrative staff for daily tasks like procurement and billing.

Why do you need your company registration number regularly?

You need your company registration number to perform critical business actions such as opening a South African business bank account, applying for government tenders, or registering for COIDA (Workmen’s Compensation). It is the primary key used to verify your business’s legal existence during any due diligence process.

In the 2026 economic landscape, financial institutions are stricter with 'Know Your Customer' (KYC) protocols. Whether you are using a traditional bank or a fintech platform, the first piece of information requested—after your company name—will be this registration number.

Opening a business bank account

When you approach a bank, they will use your registration number to pull a real-time report from the CIPC. This confirms that your company is 'In Business' and not 'Deregistration Process' or 'Deregistered'. Keeping this number handy ensures your application moves through the compliance department without delays.

Registering for VAT and PAYE

To grow your business, you will eventually hit the R1 million turnover threshold for mandatory VAT registration. To apply, SARS requires your CIPC number to verify directors and physical addresses. The same applies to PAYE if you begin hiring employees and need to deduct tax from their Rands (R) earned.

How to verify another company's registration number?

To verify if a supplier or partner is legitimate, you can perform a free 'Enterprise Search' on the CIPC BizPortal using their registration number. This will reveal the company’s current status, its registered office address, and whether it is up to date with its CIPC annual returns.

This is a crucial step in South African business to avoid fraud. By checking a company registration number in South Africa, you can see if the entity is actually active. Many businesses are automatically deregistered by the CIPC for failing to lodge annual returns, even if they are still trading.

Checking for CIPC Annual Return compliance

Annual returns are not the same as tax returns. They are a yearly 'renewal' fee paid to the CIPC to keep your company information updated. If you find a company's number and notice their status is 'AR Final Deregistration,' they are legally unable to trade or sign contracts. Always check this before entering into a significant partnership.

What if you cannot find your registration number anywhere?

If you have lost all documents and cannot find your company registration number in South Africa online, you should contact the CIPC call centre or visit a self-service terminal at a DTI office. You will need to provide your ID number and the exact name of the company to recover the records.

Often, small business owners forget that they registered a company years ago that has since been deregistered. If your search yields no results, it is possible the company was never fully incorporated or has been removed from the registry due to non-compliance with annual return filings.

Reinstating a deregistered company

If you find your number but see that the status is 'Deregistered,' you may need to go through a reinstatement process. This involves paying all outstanding annual return fees and submitting an application to the CIPC. This is a common issue for South African SMEs who overlook administrative duties during their growth phase.
