Understanding GSTIN: A Complete Guide

GSTIN (Goods and Services Tax Identification Number) is a unique 15-digit number assigned to every business registered under GST in India. It has replaced the older TIN and is now the primary identifier for tax purposes.

Structure of a GSTIN

The first 2 digits represent the state code, the next 10 digits are the PAN of the business, the 13th digit is the entity number of the same PAN holder in a state, the 14th is ‘Z’ by default, and the 15th is a check code. For example: 23AAGCB6069D1ZW.

Why GSTIN Matters

A valid GSTIN lets you collect GST, claim input tax credit, and appear as a compliant, trustworthy business to your customers and vendors. Always verify a supplier’s GSTIN before doing business.

Tip: Use the GST search on BE Code to instantly verify any GSTIN and view the registered business details.
