About GST & PAN

GSTIN is the 15-digit identity of a GST-registered business in India. It encodes the state, the company's PAN, and how many times that PAN has registered in that state - so a single number tells you where a business is registered and who owns it.

PAN is a 10-character ID issued by the Income Tax Department. The 4th character reveals the holder type - C Company, P Individual, F Firm, H HUF, T Trust, G Government - which is why every GSTIN carries a PAN inside it.

Verifying a GSTIN before you transact confirms a vendor is genuine, registered, and active - protecting you from fake invoices and ineligible input-tax-credit claims.
