What Are Company Registration Numbers?

Published June 22, 2017 · Updated October 14, 2026

Many new founders wonder what a company registration number actually is. In Malaysia, SSM gives every registered entity its own number, so no two entries on the register share one.

In this guide, we explain the distinct SSM identifiers for companies, businesses and limited liability partnerships. We cover current number formats and where to find them. We also distinguish them from tax and employer references and explain how to display them correctly. This article was first published on June 22, 2017 and fully revised for 2026.

That single string of digits follows a company everywhere. It appears on the incorporation notice, annual return, invoices, bank mandates and contracts. From sole proprietorships to multinational companies in Malaysia, every registered entity carries its own reference.

Confusion is common and costly. Founders may mix the number up with tax references or quote a dissolved entity's details on an invoice. They may also omit the number from a company website, where the Companies Act 2016 requires it. With LHDN's e-invoicing rollout, using the right references matters more than ever.

What Is a Company Registration Number in Malaysia?

A company registration number is the permanent identity SSM assigns to a company on incorporation, and it remains unchanged for the life of the company.

SSM is the national regulator responsible for company and business registration. Under the Companies Act 2016, it maintains the register of every company incorporated in Malaysia. This includes locally owned and foreign-owned companies.

When SSM registers a new Sendirian Berhad (Sdn Bhd), it issues a notice of registration that carries the company's unique number. That number is the company's legal identity. It confirms the entity exists as a separate legal person with limited liability protection for its shareholders.

A company can change its name, its directors and even its shareholders, but the number never changes. If a company is struck off and later restored, the same number returns with it. In practice, we quote this number whenever we open bank accounts, lodge annual returns or execute agreements on a client's behalf.

Which SSM Identifier Does Each Business Structure Receive?

SSM runs three separate registers — companies, businesses and limited liability partnerships — and each register issues its own numbering series.

The structure you choose determines which register you join and which identifier you receive. The three main structures are set out below.

1. Company Registration Numbers (Sdn Bhd)

A company incorporated under the Companies Act 2016 is a separate legal entity owned by shareholders and managed by directors. SSM issues a company registration number upon incorporation. The number must be quoted on the Annual Return, which is due within 30 days of each incorporation anniversary.

2. Business Registration Numbers (Sole Proprietorships and Partnerships)

Sole proprietorships and conventional partnerships are governed by the Registration of Businesses Act 1956. They must apply to the Registrar for registration no later than 30 days from the date the business commences. Because the owner and the business are legally the same person, the identifier is called a business registration number, not a company number.

3. LLP Registration Numbers (PLT)

A limited liability partnership (LLP), known locally as PLT, is registered under the Limited Liability Partnerships Act 2012. It combines a partnership's operational flexibility with a company's limited liability protection. LLPs receive their own registration series and must lodge an annual declaration with SSM.

How Do the Legacy and New Registration Formats Relate?

Legacy formats remain recognised by SSM, while the standardised 12-digit registration-number format was introduced for companies, businesses and LLPs on 11 October 2019.

The Companies Act 2016 came into force on 31 January 2017, and SSM introduced the standardised 12-digit registration-number format on 11 October 2019. Companies now receive a 12-digit number that begins with the year of incorporation, such as 202601012345 for a company incorporated in 2026.

Businesses registered under the Registration of Businesses Act 1956 receive a 12-digit number comprising the year of registration, entity code 03 and a six-digit sequence. LLPs receive a 12-digit number comprising the year of registration, entity code 04 and a six-digit sequence, without an LLP suffix. Before the change, companies and businesses shared a similar digits-and-letter style, which made the two registers easy to confuse.

The relationship between the formats is simple: they identify the same register entry. A company incorporated in 2010 kept its legacy number, such as 123456-A, and from 11 October 2019 SSM also assigned it a 12-digit number based on its 2010 registration, shown alongside the old one. Both formats appear side by side in official records, so treat any SSM-issued number on a document as valid unless a search shows otherwise.

Where Can You Find and Verify a Company Registration Number?

An SSM online search is the fastest way to verify any entity, returning its name, registration number and current status.

Most people who ask apa itu company registration number already have the number in front of them. It usually appears on an invoice, a contract or a bank form. The real question is whether it is genuine and whether the entity is still active.

The number appears in these places:

• the notice of registration SSM issues upon incorporation
• the company's Annual Return lodged each year
• business letters, invoices, receipts and official notices, which must display the number
• the company's website, where the Companies Act 2016 requires the details to appear

To verify a number, search SSM's e-Information service through the official SSM website. A company search returns the registered name, number, incorporation date and status, showing whether the entity is live, dormant or struck off. A small fee applies for certified documents.

Is a Company Registration Number the Same as a Tax Number?

No. The SSM number is a legal identity, while tax, SST, employer and social-security references are separate numbers issued by different authorities.

This is where most confusion happens. A company collects several official references during its life, and each one serves a different regulator. Mixing them up can delay filings, payments and loan applications.

1. Income Tax Reference Number (LHDN)

The Inland Revenue Board of Malaysia (LHDN) issues a tax reference when a company registers through the e-Daftar portal. It is used for corporate tax filings, including Form C and the CP204 estimate. Form C is due within seven months of the accounting period end. An existing company must submit CP204 at least 30 days before the basis period begins, while a new operating company required to submit CP204 must do so within its first three months of operations.

2. SST Registration Number (RMCD)

The Royal Malaysian Customs Department (RMCD) issues a separate SST registration number when a business crosses the registration thresholds. SST returns are due by the last day of the month following each taxable period. The SST number, not the SSM number, must appear on tax invoices.

3. Employer Reference Number (LHDN)

Once a company hires staff, LHDN assigns an employer reference for monthly PCB deductions, which are due by the 15th of the following month. The annual Form E must reach LHDN by 31 March, and Form EA must reach employees by the end of February.

4. EPF, SOCSO and EIS Codes

The Employees Provident Fund (KWSP) and PERKESO issue their own employer codes for monthly contributions. These are also due by the 15th of the following month. None of these replaces the SSM registration number.

How Should Registration Details Appear on Invoices and Websites?

A company must state its name and registration number in legible characters on all business letters, invoices, receipts, official notices and its website.

The Companies Act 2016 sets out the display rules. In practice, use a consistent document footer:

• Company name
• Registration number
• Registered office address

For example: Nusantara Tech Solutions Sdn Bhd (202601012345).

Sole proprietors and partnerships must display their certificate of registration at every place of business. An LLP must likewise state its name and registration number on its letters and notices. Websites should carry the details in the footer so customers and banks can verify the entity instantly.

Display rules are also practical protection. Under LHDN's e-invoicing framework, being phased in since August 2024, company e-invoices must carry both the TIN and the SSM registration number. A mismatch between the two can cause an invoice to be rejected.

Finally, remember that a registration number protects identity, not brand. Registering a company name with SSM does not stop others from using a similar brand. For that, our article How Do You Register a Trademark in Malaysia? explains the process.

Why Do Banks and Regulators Rely on These Numbers?

Every serious counterparty — from banks to government agencies — uses the registration number to confirm exactly which legal entity it is dealing with.

Banks and regulators rely on these numbers because they need a stable, verifiable way to match a legal entity across different systems. When you open a corporate account, the bank uses the SSM registration number for know-your-customer checks, entity matching and compliance screening. Regulators use the same number to trace filings, enforcement actions and ownership records back to one legal person.

A company can change its name, directors and shareholders, but the registration number stays constant. That makes it the most reliable identifier for due diligence, loan applications, contracts and statutory filings. Before you commit to any counterparty, verify the number through SSM's online search so you know the entity is live and correctly identified.

Conclusion

A company registration number is the one constant in a company's life. SSM assigns it at incorporation, and it remains unchanged for the life of the company. It is required on nearly every official document. Companies, businesses and LLPs each draw from a separate register, and the standardised 12-digit format introduced on 11 October 2019 uses entity codes to make the series easier to tell apart at a glance.

Keep that number distinct from your LHDN, RMCD, KWSP and PERKESO references. Display it correctly on invoices and your website. Verify any counterparty through SSM's online search before you commit.
