Before you issue an invoice or claim input tax credit, verifying your vendor’s GSTIN (Goods and Services Tax Identification Number) is essential.

Instantly know if the GSTIN is valid, active, suspended, or incorrect, and you can safeguard your business from errors, fraud, or disallowed ITC claims.

Why Verify a GST Number?

In today’s fast-paced business environment, failing to verify a vendor’s or customer’s GSTIN can lead to serious consequences. Here’s why verifying GST numbers is not just important, but critical:

Prevent GST Fraud: Fake GST numbers are used by fraudulent entities to evade taxes or issue bogus invoices.
Ensure Input Tax Credit Eligibility: You can only claim ITC on purchases made from valid, GST-registered vendors.
Improve Vendor Onboarding: GST verification is a key step during vendor due diligence or KYC.
Maintain GST Compliance: Filing returns with wrong GSTINs can trigger errors, notices, or even penalties from tax authorities.
Build Business Trust: Validating GSTINs demonstrates that your business is committed to compliance and transparency.

Simply enter the 15-digit GSTIN in the search box and click on ‘Validate.’ The tool will fetch real-time data, indicating whether the GSTIN is valid, registered, and active, along with details such as the legal name, state code, and taxpayer type.
How to find a vendor’s GST number?

Usually, vendors provide their GSTIN on invoices, quotations, or contracts. You can also request it during onboarding or verify it via the GST portal if you know their PAN or business name..

No, GSTIN validation works only by inputting the 15-digit GSTIN number. However, once you enter the GSTIN, the tool will display the legal name associated with that number, helping you verify if it matches your vendor’s name.
What to do if a GSTIN is invalid?
If the GSTIN is flagged as invalid:
- Double-check for spelling or numeric errors
