The Central Supplier Database (CSD) is the South African government's single, centralised repository of all entities seeking to do business with national, provincial, and most municipal government organs of state. Hosted at supplier.gov.za and administered by National Treasury, the CSD was introduced in 2015 to replace a fragmented landscape of department-specific supplier databases that were difficult to maintain, inconsistent in their data requirements, and vulnerable to fraud. By consolidating all supplier information in one place, the CSD enables procurement officials to verify supplier eligibility in real time and reduces the administrative burden on both suppliers and procuring institutions.
Before the CSD, companies had to register separately with each government department they wished to supply. This meant maintaining dozens of different supplier database entries with varying data requirements, separate tax clearance submissions, and no single authoritative source of truth about a supplier's compliance status. The result was that the same company might be active in one department's database but unknown to another, and there was no mechanism for government to identify a blacklisted or non-compliant supplier across all departments simultaneously. The CSD solved these problems by creating a single, live-linked database that is checked by all participating procuring institutions.
CSD registration is mandatory for all entities — companies, close corporations, trusts, non-profit organisations, sole traders, and partnerships — that wish to receive payment from any organ of state governed by the PFMA or MFMA. This includes not only formal competitive bid contracts but also quotations, emergency procurements, and any other form of contract above a de minimis threshold. A supplier without a valid, active CSD registration will be disqualified from consideration for any government contract and cannot receive payment even on a verbal or low-value order.
The CSD assigns each registered entity a unique CSD number, which serves as the primary identifier in all government procurement transactions. This number is linked to your CIPC company registration number, your SARS tax number, and your banking details. Procurement systems across government — including the Basic Accounting System (BAS) and Standard Chart of Accounts (SCOA) — use the CSD number to verify supplier eligibility before processing payments. If your CSD number is inactive or your details are outdated, payment can be blocked even on an existing contract.
The CSD has several registration categories. Companies registered under the Companies Act, close corporations registered under the Close Corporations Act, and co-operatives each have their own registration pathway. Individuals (natural persons) registering as sole traders have a separate pathway that uses their ID number rather than a CIPC registration number. Non-profit organisations registered under the Non-Profit Organisations Act and public benefit organisations with SARS PBO status have additional documentation requirements related to their governance structures and statutory compliance. Understanding which category applies to your entity before starting the registration process prevents frustration with incorrect documentation.
A frequently misunderstood aspect of the CSD is the verification process. When you register and submit documents, the CSD system automatically cross-checks your details against the CIPC register (for company registration status), SARS eFiling (for tax clearance status), and your bank's verification service (for account validity). These are live integrations that update in real time. This means that your CSD status is not a static record that remains correct once set — it is a dynamic reflection of your current compliance status with CIPC, SARS, and your bank. Any lapse in CIPC annual returns or SARS tax compliance will automatically affect your CSD status, which is why ongoing maintenance is as important as initial registration.
