What is GST Verification?
GST verification means checking whether a GSTIN (GST Identification Number) is valid, active, and genuinely registered on the GST portal. It helps you confirm the identity and registration status of any business before entering into a transaction.
This free tool pulls real-time data from government records — so you can verify any GSTIN in seconds without logging into the GST portal.
Why is GST Verification Important?
Verifying a GSTIN before doing business protects you from fraud and compliance issues:
- Detect fake GSTINs: Some vendors show fake or cancelled GST numbers on invoices
- Claim valid ITC: Input Tax Credit (ITC) is only valid if your supplier has a genuine, active GSTIN
- Avoid GST notices: Transactions with cancelled or suspended dealers can trigger scrutiny
- Due diligence: Verify new vendors, distributors, or customers before onboarding
- Loan/tender compliance: Banks and government agencies require verified business details

What to Do If You Receive an Invoice with Invalid GSTIN?
If the GSTIN verification shows the number as cancelled or fake:
- Do NOT claim ITC on that invoice
- Contact the vendor immediately and ask for a corrected invoice
- If vendor refuses, report the issue on the GST portal (grievance section)
- Consult a CA if you have already claimed ITC on such invoices
