What is a PAN? Why does it appear in the e-invoice? Can I update my PAN?

The permanent account number (PAN) is a unique 10-digit alphanumeric number issued by India’s income tax department to taxpayers. The PAN is pre-populated in the e-invoice section based on the third to 12th characters in your GSTIN. If you change your PAN, you also need to update your GSTIN accordingly in the e-invoice section.
