🔍 GSTIN Validator & Decoder

Validate and decode any 15-digit GSTIN — state, PAN, entity type

ℹ️ Simulation only — the "Browse Demo GSTINs" feature uses demo data for educational practice. The validator decodes GSTIN format locally — no government portal or real GST data is accessed.

Enter GSTIN (15 characters)

Format: 2 (state) + 10 (PAN) + 1 (entity) + Z + 1 (check digit)

GSTIN Structure Guide

Characters 1–2: State/UT code (01 = J&K, 07 = Delhi, 27 = Maharashtra, 29 = Karnataka, 33 = Tamil Nadu…)

Characters 3–12: PAN of the taxpayer (10 chars). 4th character of PAN indicates entity type: P=Individual, C=Company, H=HUF, F=Firm, A=AOP, T=Trust

Character 13: Entity number (1–9, then A–Z) — multiple registrations under same PAN in same state

Character 14: Always 'Z' (default)

Character 15: Check digit (0–9 or A–Z) — validates the entire GSTIN
