Procurement
Supplier & vendor GST verification
Check a supplier or vendor GSTIN before onboarding, before payment and whenever the paperwork looks off.
Example:
A practical verification workflow
1. Collect the GSTIN at onboarding
Ask for the 15-character number in the vendor form rather than reading it off a later invoice.
2. Validate the structure
A wrong check character or an impossible state code means the number is mistyped or invented.
3. Verify the registration
Confirm the GSTIN resolves to a live registration and note the legal and trade names.
4. Match the name and state
Compare against the vendor master record and the address on the purchase order.
5. Re-check periodically
Registrations get cancelled or suspended after onboarding; re-verify long-standing vendors.
Where this fits
Supplier onboarding, invoice checks and procurement due diligence all rely on the same lookup. If the number came off a bill, see GST invoice verification. For the corporate-counterparty angle, see business GST verification.

Frequently asked questions
How do I verify a supplier's GSTIN?
Enter the supplier's 15-character GST number above. The result page shows the registration status, legal name, trade name and taxpayer type returned by our verification source.
Is vendor GST verification the same thing?
Yes. Vendor GST verification and supplier GST verification describe the same check, so both are handled on this page.
How often should suppliers be re-verified?
There is no fixed rule. Many teams re-check active vendors periodically and always before a large payment, because a registration can be cancelled at any time after onboarding.
Does a valid GSTIN guarantee the supplier is trustworthy?
No. It confirms the registration exists and its current status. It says nothing about the supplier's return filing, solvency or conduct, and it is not a compliance guarantee.
