From one PAN to every GST registration a business holds
A business can hold a separate GSTIN in each state it operates in. Mapping a PAN to all of them is essential for vendor risk and reconciliation.
Why one business has many GSTINs
GST registration is state-wise. A company headquartered in Maharashtra with warehouses in Karnataka and Delhi will hold three GSTINs, all sharing the same PAN. If you only checked the GSTIN on the invoice in front of you, you would miss the other two.
The PAN-to-GST lookup returns every GSTIN registered against a PAN, with each registration status and state.
Uses in vendor risk
A vendor with one cancelled GSTIN among five active ones is a different risk profile from one with a single clean registration. Pulling the full picture lets your procurement team see the pattern before a contract is signed.
It also catches the case where a vendor quotes a clean GSTIN for the deal but routes invoices through a cancelled one.
Reconciliation and TDS
When money comes in from a business customer, matching it to the right GSTIN (the one for the state the supply was made in) keeps your GST returns clean. The PAN-to-GST map is the lookup table that makes that automatic.
