The Central Supplier Database is the single register of suppliers wanting to do business with the South African state, run by National Treasury.
Registration is free and you do it yourself, online. You need the business registration details, tax number, bank account and B-BBEE information, and the system verifies most of it automatically against SARS, CIPC and the banks.
Anyone charging you to register is selling you something you can do at no cost, and a consultant promising a guaranteed tender is committing fraud. Tenders are advertised publicly and awarded through a documented process; nobody can promise one.
This page covers how to contact the Central Supplier Database in South Africa. The details below were taken from the official Central Supplier Database contact page rather than from any third-party directory.
ContactDetails.co.za is an independent directory. We are not the Central Supplier Database and cannot act on your behalf. Everything on this page is a routing aid so you reach the right official channel quickly.
The Central Supplier Database contact numbers
We could not verify a contact number for Central Supplier Database. Its website at csd.gov.za builds its pages in the browser rather than serving them as fixed pages, so there were no readable contact details on it to confirm when we checked on 22 August 2026.
We have deliberately not published a number here. An unverified number is worse than none: it sends people to whoever happens to answer it, which is exactly the mechanism behind contact-detail scams.
Registering on the Central Supplier Database is free. Every business wanting to supply goods or services to the South African state must be registered on it, and registration is done online by the supplier. Anyone charging you to register is selling you something you can do yourself at no cost, and consultants offering guaranteed tenders are running a fraud.
Self-service options before you call
- Check the official site at csd.gov.za, which carries the current contact details and any online enquiry form.
- Calling outside peak times. Monday mornings and the hour after 17:00 are usually the worst for South African contact centres.
What to have ready before you call
- A clear one line summary of what you need resolved.
- Your account, order or reference number if you already have one.
- The identity document or account holder details, since most South African providers verify who you are before discussing an account.
- Dates, amounts and any error message exactly as it appeared.
- A pen and paper for the reference number. Ask for one every time, because without it a follow up call starts from nothing.
Selling to the South African state
- Registration on the Central Supplier Database is free and done by the supplier. No consultant is required and nobody may charge you for it.
- Tenders are advertised publicly, on the eTenders portal and in the Government Tender Bulletin. Anyone claiming private access to an unadvertised opportunity is lying.
- Nobody can promise you an award. Bids are evaluated against published criteria by a committee, and a guaranteed tender for a fee is a fraud.
- Your tax and B-BBEE status must be current, and the CSD verifies tax compliance automatically against SARS. A lapsed status disqualifies a bid.
- Government must pay valid invoices within thirty days. Where it does not, the department’s supply chain unit and then the relevant treasury are the escalation route.
Keep the order number, the invoice number and the proof of delivery. Every payment query turns on those three, and a supplier who cannot produce them has no enquiry to make.
Complaints and escalation
If a first call does not resolve the matter, escalate through the department’s own supply chain management unit in writing, then the National Treasury. Registration on the Central Supplier Database is free and done by the supplier, and tender opportunities are advertised publicly. Anyone offering a guaranteed tender for a fee is committing fraud, and that is a matter for the South African Police Service.
Keep a short written log of each contact: the date, the channel you used, the name of the agent and the reference number. Most public procurement complaint processes ask for exactly that history, and having it ready is usually the difference between a fast resolution and starting over.
Avoiding fake Central Supplier Database contact numbers
Contact details for well known South African brands are a common target for impersonation. Numbers that look official appear in search ads, social media replies and cloned websites, and the person answering is not the Central Supplier Database.
- Reach Central Supplier Database through the official site at csd.gov.za rather than through a number in a search advert or a social media reply.
- The Central Supplier Database will never ask you for your full card number, PIN, CVV, online banking password or a one time PIN. Nobody legitimate needs those to help you.
- Treat any caller who creates urgency, asks you to install remote access software, or asks you to move money to a safe account as fraudulent, and end the call.
- If you are unsure whether a call was genuine, hang up and dial the official number yourself rather than calling back a number the caller gave you.

Frequently asked questions
What is the Central Supplier Database contact number?
We do not publish one, because we could not confirm a number on an official source. Numbers do circulate on directory sites, and we do not republish those.
How do I know a Central Supplier Database number is genuine?
Check it against the official site at csd.gov.za. A number that only appears in a search advert, a social media reply or a third-party directory should not be trusted for anything involving your account, your money or your identity document.
What should I do if nobody resolves my query?
Ask for the complaint reference and the escalation path on your first call, then follow the escalation route described above. Keep the dates, agent names and reference numbers, because every formal complaint process will ask for them.
Can ContactDetails.co.za resolve this for me?
No. We are an independent directory, not the Central Supplier Database, and we have no access to your account. Everything here is a routing aid so that you reach the correct official channel with the right information in hand.
Is there a cost to calling these numbers?
South African 0860 and 0861 numbers are charged at a share-call or standard rate depending on your provider, and 0800 numbers are toll free from a landline. Calls from a mobile are billed at your own operator’s rate, so check your plan if cost matters.
