Central Supplier Database Registration: how to get your business onto the CSD, and how businesses quietly fall off it

The Central Supplier Database is National Treasury's single register of suppliers to government. Since 1 April 2016 every supplier doing business with an organ of state should be registered on it. You self-register on the CSD portal, Treasury verifies your details against SARS, CIPC, Home Affairs and your bank, and a supplier number is issued once verification passes.

Most guides stop at the registration steps, which is the easy half. The half that costs businesses work is what happens afterwards, because the CSD does not hold a snapshot of you. It holds interfaces to the institutions that hold the truth about you, and it keeps asking them.

What the CSD is, and the problem it was built to solve

Before the CSD, there was no single supplier register for government. National Treasury's own factsheet is blunt about the state it was fixing: no single consolidated comprehensive supplier database existed for national, provincial and local government, which caused duplication and fragmentation of supplier information across spheres of government.

The scale of that fragmentation is the detail worth holding on to. Treasury estimated that approximately 600 different supplier databases in government would be migrated into the CSD. Six hundred separate registrations, each with its own forms, its own document requirements and its own expiry dates.

Treasury states the purpose directly: to reduce duplication of effort and cost for both business and government while enabling electronic procurement processes. Register once, for the whole of government, instead of once per department.

Who has to register?

Treasury's factsheet is explicit that this is not limited to companies. All suppliers doing business with government should be registered on the Central Supplier Database, and the listed categories are:

• Private companies, PTY (LTD)
• Public companies (LTD)
• Close corporations
• Sole proprietors
• Individuals
• International companies
• NGOs, including section 21 companies
• Joint ventures
• Partnerships
• Trusts and consortiums
• Government and public entities

Sole proprietors and individuals being on that list matters. A one person consultancy with no registered company is not exempt, and the identity verification route exists precisely for suppliers who have no CIPC registration to check.

What the CSD verifies automatically, and against whom

This is the part that changes how you should think about the CSD. It is not a form you fill in. It is a set of live interfaces to other institutions. Treasury's factsheet lists the vetting the CSD performs:

What is verified	Verified against
Tax compliance status	South African Revenue Service
Business registration and business ownership	Companies and Intellectual Property Commission
Bank account and bank account holder	Banking verification services
Citizen identity number	Department of Home Affairs
Empowerment information	IRBA and SANAS
Government employee status	Government payroll systems, including PERSAL and PERSOL, e-declarations and municipal payroll
Restriction status	The register for tender defaulters and the database of restricted suppliers

Two of these are not about your paperwork at all, and both are worth knowing about in advance.

The government employee check. The CSD verifies whether the people behind a supplier are government employees, against state payroll systems. If a director or owner is employed by the state, that is a conflict question that will surface automatically rather than being something you get to disclose or not.

The restriction check. The CSD checks the register for tender defaulters and the database of restricted suppliers. Restriction is not a document you can be missing. It follows the entity and the people behind it.

What you need before you start

Treasury's factsheet lists what registration asks for:

1. Supplier registration information: name, address and contact details
2. Valid tax compliance evidence
3. Valid empowerment evidence
4. Valid CIPC registration, where the supplier is a registered entity
5. Identification documents of owners, partners and joint venture parties
6. Bank account details
7. The commodities in which the supplier trades

One note on the tax item. The factsheet was written when the paper tax clearance certificate still existed. That document was replaced in 2015, and what a supplier now has is a Tax Compliance Status PIN, which lets a verifier check the live position rather than read a certificate. We cover exactly how that works in the guide to the Tax Compliance Status PIN, and it is directly relevant here, because the CSD's SARS interface is consuming the same live answer.

The commodities item is the one suppliers under-invest in. Treasury describes the CSD distributing supplier information to subscribing departments and municipalities based on commodities. Your commodity selections are how buyers find you. A thin or wrong commodity list is a registration that technically exists and never surfaces.

The part that catches suppliers: your standing expires with your compliance

Here is the line from Treasury's factsheet that does not appear in most CSD guides, and it is the single most useful sentence on this page. Upon expiry of a supplier's compliance information, such as tax and empowerment evidence, a supplier would need to renew their supplier status in order to retain their status on the CSD.

Read that against how tax compliance now works. SARS states that when a compliance PIN is used for verification, the result reflects the current status at the date and time it is used. So the CSD is not checking a document you submitted once. It is asking SARS, and SARS is answering about today.

Which produces a specific and quiet failure. You register correctly. You are verified. Months later a return goes unfiled, your tax status goes non-compliant, and your supplier standing degrades automatically, without an application being refused and without anyone writing to you. The registration is still there. It just no longer says what you think it says.

Treasury also puts the responsibility for this squarely on the supplier. Its terms require the primary user to ensure that all the requisite supplier information on the CSD is complete, up to date and accurate, and state that the National Treasury shall not be liable for any loss or damage as a result of the provision of inaccurate supplier information on the CSD by the primary user.

There is no ambiguity in that division. The verification is automatic. The consequences are yours.

How this connects to the rest of your compliance

The CSD sits at the end of a chain rather than at the start of one, and that is why it appears to fail for unrelated reasons.

1. Company standing. Unfiled CIPC annual returns put your company record out of order, and the CSD reads CIPC directly for registration and ownership.
2. Tax standing. Covered above, and it is the link that moves most often, because filing obligations recur monthly and annually while your CSD registration feels like a one time event.
3. Empowerment evidence. An affidavit that has aged out is not evidence. The validity rules are narrow and mostly not obvious, which is why we wrote the B-BBEE affidavit guide separately.
4. Verification discipline generally. If you deal with regulated clients you are already living with this pattern, as FICA obligations show in a different sector.

Every link behaves the same way. None of them announce themselves when they break.

Where the law is going

The procurement framework around the CSD is mid-change, and it is worth knowing the status so you are not surprised.

The Public Procurement Act 28 of 2024 is the new governing statute, and its full operationalisation depends on regulations that are not yet promulgated. The draft General Public Procurement Regulations were published for comment in Government Gazette 54528 on 16 April 2026, the Minister of Finance granted a further comment period by a subsequent gazette, and comment closed on 15 July 2026.

Nothing in that process changes what a supplier should do now. Being registered, verified and current is the precondition under the existing framework and under any version of the new one. Circulating claims about specific new thresholds are not yet confirmed against the promulgated text, so treat any figure you see quoted as provisional until the regulations are published.

Frequently Asked Questions

Do I have to register on the CSD to do business with government?

Yes. National Treasury's position is that all suppliers doing business with government should be registered on the Central Supplier Database, and the CSD has been the single source of supplier information for organs of state since 1 April 2016.

Can a sole proprietor register on the CSD?

Yes. Treasury's listed supplier categories include sole proprietors and individuals alongside companies, close corporations, trusts, partnerships and joint ventures. Suppliers without a CIPC registration are verified through identity verification with the Department of Home Affairs instead.

What does the CSD check about my business automatically?

Tax compliance with SARS, business registration and ownership with CIPC, your bank account and account holder, identity numbers with Home Affairs, empowerment information, government employee status against state payroll systems, and the registers of tender defaulters and restricted suppliers.

Why did my CSD status change when I did not change anything?

Because the CSD re-derives your status from other institutions. Treasury states that when a supplier's compliance information expires, the supplier must renew their status to retain it on the CSD. A lapsed tax or empowerment position degrades your standing automatically.

Whose responsibility is it to keep CSD information correct?

The supplier's. Treasury's terms require the primary user to keep all requisite supplier information complete, up to date and accurate, and state that National Treasury is not liable for loss or damage caused by inaccurate supplier information provided by the primary user.

Does registering on the CSD mean departments will find me?

Only if your commodity selections are right. Treasury describes supplier information being distributed to subscribing departments and municipalities based on commodities, so an incomplete commodity list produces a valid registration that buyers never see.
