What is the GST State Code List?

GST stands for Goods and Services Tax, and the GST state code list is a list of unique numerical codes assigned to every state and Union Territory in India. This code is used in GST transactions. For example:

01 represents Jammu & Kashmir
33 represents Tamil Nadu
36 represents Telangana

The GST jurisdiction is a vital aspect that these codes help in determining, mainly for inter-state and intra-state transactions. The GST state codes form a component of the 15-digit GSTIN (Goods and Services Tax Identification Number) and thus are required for compliance with the GST.

Structure of a GSTIN and the Role of State Codes

GSTIN is a permanent account number for Goods and Service Tax (GST)-registered businesses and consists of 15 digits (alphanumeric). Here’s how it is structured:

First Two Digits: GST state code, e.g., 33 for Tamil Nadu.
Next: Next Ten Characters: PAN (Permanent Account Number) Of Business.
13th Digit: Entity code (describes several registrations in the same PAN).
14th Digit: Blank by Default.
15th digit: A checksum for verification.

Example: GSTIN starting with 33 belongs to Tamil Nadu. This makes sure transactions are written to the correct jurisdiction.
