Why GST state codes matter
First 2 digits of a GSTIN
Every 15-character GSTIN starts with the state code. 27AAAAA0000A1Z5 is registered in Maharashtra (27).
Decides CGST/SGST vs IGST
If supplier and buyer state codes match, charge CGST + SGST. If they differ, the supply is inter-state and IGST applies.
Based on GSTN numbering
Codes follow the Census 2011 state numbering used by GSTN — not vehicle RTO series. Use this list for tax and GSTIN checks.

FAQ
GST state code FAQs
What is a GST state code?+
A GST state code is a 2-digit number that identifies the state or union territory of registration. It forms the first two digits of every 15-character GSTIN — for example, 27 is Maharashtra and 24 is Gujarat.
How do I find the state from a GSTIN?+
Read the first two digits of the GSTIN and match them to this list. For example, a GSTIN starting with 29 is registered in Karnataka.
Why do GST state codes matter for invoicing?+
They decide whether a supply is intra-state (CGST + SGST) or inter-state (IGST). If the supplier and customer state codes match it is intra-state; if they differ it is inter-state.
Are GST state codes the same as vehicle RTO codes?+
No. GST state codes follow the Indian Census 2011 state numbering used by GSTN, not RTO registration series. Always use the GST list for GSTIN and tax purposes.
