Registering on the Central Supplier Database
How a South African business registers on National Treasury's Central Supplier Database, what to have ready, and the details that hold registration up.

A municipality asks for three quotes for office furniture, a provincial department needs a plumber for a clinic, a national entity wants a training provider. Before any of them can buy from your business, they need to find you, and they look in one place: National Treasury's Central Supplier Database.
Registration is done online by the supplier itself, but it trips up many small businesses. A missing director's detail, a bank account that has not been verified, or commodities captured too vaguely can leave a business registered on paper and invisible in practice. This guide walks through what the database is for, what you need, how registration works and how to make sure buyers can actually find you.
One source of supplier information for the state
National Treasury describes the Central Supplier Database, the CSD, as the single source of supplier information for organs of state. Departments, municipalities and public entities draw supplier details from it rather than keeping their own lists.
That has a consequence for suppliers. National Treasury says supplier details are verified with institutions such as SARS, CIPC and Home Affairs, so what you capture has to agree with what those institutions already hold. Details that differ, such as an old address or a director's name spelt differently, are the kind of thing that turns into a query.
What to have ready before you start
National Treasury's CSD registration process page lists what a supplier needs and how its details are verified. According to National Treasury, registration requires:
- a valid cellphone number, which receives a one-time PIN;
- an e-mail address;
- the supplier's ID or registration number;
- its address;
- the directors' details;
- the commodities the business supplies; and
- where relevant, bank and tax information.
Gather these in one place first. For a company, the directors' details should match CIPC's records exactly, because the CSD checks them against CIPC. A director who resigned years ago but was never removed from CIPC's register is a common cause of mismatches.
Bank details deserve particular attention. National Treasury says bank verification may take up to four days, and advises capturing bank details in advance to avoid payment delays. A supplier that waits until it has won its first order to add its bank account may wait for its first payment too.
Two stages of self-registration
National Treasury describes CSD registration as a two-stage self-registration:
- Create a CSD user. You register a user and activate it with the one-time PIN sent to your cellphone.
- Add the supplier. Logged in as that user, you capture the supplier's details and submit them.
Keep the user's login details safe and in the business's hands, not only with a consultant who registered you. You will need them to update details later.
Supplier number and registration reference
National Treasury says registration is complete once the supplier is assigned a supplier number and a 36-digit unique registration reference number, which are used to obtain a registration report. Buyers and tender documents ask for one or both, so keep the registration report somewhere your team can find it quickly. A CSD registration number is not the same as a tax compliance status pin; tax good standing for tenders covers that separate requirement.
Commodities, locations and being found
This is the step that makes the difference between registered and discoverable. National Treasury says suppliers must capture their commodities and delivery locations accurately on the CSD, because organs of state use them to search for suppliers and send requests for quotations.
Think like a buyer searching the database. A business that services air conditioners and lists only a broad category may never appear in a search for that service. One that supplies across a province but lists only its home town may never be asked to quote elsewhere. Capture each commodity you actually supply and each area you can actually deliver to, and review the list when the business changes.
Finding tenders in Achekam
Registration puts you in front of buyers who search the CSD. Open tenders are a separate stream. Achekam's tender scout reads live adverts from National Treasury's eTenders public data feed and from any public RSS or Atom feed you add, and staff can also capture a tender by hand with its documents. Sources such as CIDB, Transnet and Eskom are shown as not connected. If an RSS tender has no closing date, it is given one 30 days after publication, so check the real closing date in the advert.
The tender "AI Match" score and the Recommended list are not produced by an AI model. They come from fixed keyword, sector, province and value rules applied to the search profile you set up. That makes the profile worth the same care as your CSD commodities: describe what you do and where you work, and the matching rules have something accurate to work with. When a tender is worth pursuing, lodging a tender bid covers the submission.
A CSD readiness checklist
- Directors on CIPC's records match the people you will capture
- Business cellphone and e-mail address under the business's control
- Bank details captured early, with the verification time in mind
- Tax details current
- Commodities captured specifically, not just by broad category
- Delivery locations matching where you can really deliver
- Registration report saved where bid documents are prepared
Treat your CSD profile as a shop window that buyers search, not a form you fill in once. Review it whenever your directors, bank account, products or service area change.
General guidance only, not advice on your own circumstances. Tax and payroll rules change: check the current position with the authority or your adviser.
