How to register on the CSD
The Central Supplier Database (CSD) is National Treasury's list of businesses that can supply government. Government buyers check it before they pay you, so you need a CSD supplier number to bid on most tenders.
Last checked against official sources on 2 November 2026. Rules change: confirm on the official portal before you submit.
Who needs it
- Any company, close corporation, sole proprietor or individual who wants to sell to national, provincial or local government, or to state entities
- Not required for private clients only
Before you start
Tick these off as you gather them.
Step by step

Add your tax number, and your VAT number if registered. Enter your tax compliance status PIN where asked.
Add every director or member with their contact details, shareholding and suburb.
Select the commodities you supply and whether you deliver province-wide or nationally.
Add your B-BBEE details.
Submit and write down your reference. Your supplier number starts with MAA. Check your email (and spam folder) for the verification result.

Fix a problem
The issues people hit most, and what to do.
My tax status shows as not compliant or not verified
CSD checks your tax status with SARS automatically. Usually you have no active Good Standing PIN, it has lapsed, or SARS shows outstanding returns or debt. Fix the issue on SARS eFiling, request a new Good Standing PIN, then enter it on your CSD profile. See tax compliance PIN.
Bank verification failed
The account holder name must match your registered business name exactly. Get a fresh bank confirmation letter (under 3 months old) in that exact name, re-enter the details and redo the OTP step.
Director or company details do not match
CSD compares your details with CIPC and Home Affairs records. Make your CSD entries match your CIPC documents and IDs exactly. If CIPC itself is wrong, update CIPC first, then CSD.
My submission is stuck or I heard nothing
Check your spam folder, then log in to see your profile status. Incomplete sections and session time-outs are common causes, so save often. If nothing has moved after about 7 working days, contact CSD support through the portal.
A tender was rejected because my CSD details differ
Bid documents are checked against your CSD profile on the day. Update your profile (especially tax, bank and director details) before you bid, and make your bid forms match it.
What it costs
| Route | What you pay |
|---|---|
| Do it yourself on the CSD portal | Nothing. There is no registration fee to register yourself. |
| Pay an agent to do it | Agents charge a service fee on top. You still get the same CSD number. |
Getting your tax affairs in order first (missing returns, debt) can cost more than the registration itself.
How long it takes
The form takes about 30 to 45 minutes once you have everything ready. Verification then takes a few working days: published estimates range from 3 to 10 working days, and SARS checks are often the slow part. Plan for up to two weeks before a tender deadline.
When it expires
- Your registration does not expire on a fixed date, but you must keep your details current and confirm them at least once a year
- Your tax status is rechecked with SARS, so a lapsed PIN or new tax debt can flag your profile at any time
- Update the profile whenever your bank, directors, address or tax details change
What comes next
- Keep your tax compliance PIN in Good Standing
- Get your B-BBEE affidavit ready for bids
- Many tenders also ask for a COIDA letter of good standing
