How do I verify a supplier's GST number in India?

Enter the 15-digit GSTIN in the verifier above. The tool will instantly decode the state code, entity type, and embedded PAN. For live GST portal verification (active/cancelled status), use the official GST portal at gst.gov.in/services/searchtp after the format check.

What does a GSTIN number tell you about a supplier?

A GSTIN (15 characters) contains: 2-digit state code, 10-digit PAN, 1-digit entity number, 'Z' (default), and 1 check digit. This tells you which state the supplier is registered in, their PAN (tax identity), and whether they are a primary or additional business entity.

What is ITC eligible GST in B2B procurement?

ITC (Input Tax Credit) means businesses can reclaim the GST paid on purchases against their own GST liability. In B2B procurement, buying from a GST-registered supplier gives you an ITC claim — reducing your effective procurement cost by 5–18% depending on the product category.

💰 Why GST verification matters for B2B buyers: When you purchase from a GST-registered supplier and receive a GST invoice, you can claim Input Tax Credit (ITC) — offsetting the GST paid against your own GST liability. At 18% GST on equipment, this effectively reduces your procurement cost by 18%. Always verify a supplier's GSTIN before placing a B2B order.

How This Tool Works

Format check: The GSTIN must be exactly 15 characters — 2-digit state code + 10-digit PAN + entity number + 'Z' + check digit.

State decode: The first 2 digits map to one of India's 37 GST state codes — revealing where the supplier is registered.

PAN extraction: Characters 3–12 are the supplier's PAN number — their permanent income tax identity. Cross-check with the supplier's TAN if needed.

Live status: For real-time active/cancelled/suspended status, click the "Verify Live on GST Portal" button. This opens India's official GST search portal (gst.gov.in) — free, no login required.

Frequently Asked Questions

What does "invalid GSTIN format" mean?

It means the 15 characters don't match the official GSTIN structure. Common issues: wrong length, invalid state code (must be 01–37), non-alphanumeric characters, or the 14th character is not 'Z'. Ask the supplier to recheck their registration certificate.

Can this tool tell me if a GSTIN is active or cancelled?

This tool validates the format and decodes the embedded information. For live active/cancelled status, use the official GST portal at gst.gov.in — click the "Verify Live" button after the format check. The official portal is free and requires no login.

How do I find a supplier's GSTIN?

Ask the supplier directly — every GST-registered business is required to display their GSTIN on invoices, letterheads, and their physical business premises. On VincitaMart, all listed suppliers are GST-verified before listing.
