The first two GSTIN digits identify the state or union territory, not the exact ward, circle, division, range or officer. Check the registration certificate and GST Portal profile for jurisdiction details, use CBIC’s ‘Know Your Jurisdiction’ resources for central formations, and use the relevant state tax directory for state formations. Administrative allocation is not determined merely by whether supplies are intra-state or inter-state.
How this 2026 guide was prepared
The supplied draft was treated as a topic brief, not as legal authority. Outdated portal dates, overbroad thresholds, invented procedures and incorrect rate or format claims were corrected against official GST, CBIC, GST Council and India Code materials available on 2026-07-28.
Effective-date warning: GST rates, exemptions, portal screens and due dates can change. Confirm the live notification and return period before acting.
What jurisdiction means
A taxpayer can be administratively assigned to central or state tax authorities, while powers are cross-empowered in many contexts. Territorial formations include commissionerates, divisions and ranges centrally, and zones, divisions, circles or wards under state systems. The proper officer for a notice may differ from a generic local office.
Why the source rule is wrong
It is incorrect to say intra-state traders fall under state jurisdiction and inter-state traders under central jurisdiction. Administrative division historically uses turnover-based allocation and agreed state-centre sharing, with separate rules for new registrations. Supply type determines IGST versus CGST/SGST treatment, not by itself the administering authority.
Find details on the GST Portal
Search the GSTIN publicly to confirm legal name, status and jurisdiction fields available. After login, review My Profile and download REG‑06. For a notice, read the issuing authority, designation, DIN and statutory provision rather than assuming the profile officer owns every matter.
Use central and state directories
For central jurisdiction, use CBIC GST/CGST commissionerate resources and ‘Know Your Jurisdiction’ pages. For state jurisdiction, use the official commercial-taxes or state GST portal. Search by principal place address and pincode, then verify boundary descriptions.
If mapping appears wrong
Check the registered principal place, pincode and REG‑06 first. File the correct registration amendment if the address itself is wrong. For an administrative mapping issue, raise a GST grievance or approach the named jurisdictional office with REG‑06 and address evidence; do not create a fresh registration merely to change an officer.
Notices and communication safety
Respond within the notice channel and deadline. Verify DIN where applicable, use official contact details, and never send credentials or OTPs. A jurisdiction objection should be raised formally while protecting the substantive response deadline.
Need a transaction-specific GST review?
Check registration, classification, value, place of supply, input credit, documents and return treatment before filing.
Request GST supportFrequently asked questions
Do the first two GSTIN digits identify my officer?
No. They identify the state or union territory only.
Does inter-state trade put me under central GST?
No. Administrative allocation is not determined solely by inter-state supply.
Where is jurisdiction shown?
Check REG‑06, the GST Portal profile and public taxpayer search fields.
Can both centre and state officers act?
Cross-empowerment exists, but the proper officer and proceeding-specific rules must be checked.
How do I correct an address error?
Use the prescribed core-field registration amendment and supporting evidence.
Should I ignore a notice from an unfamiliar office?
No. Verify it, preserve the deadline and raise jurisdiction concerns formally.
Is state code 27 Maharashtra?
Yes, but it does not identify the Maharashtra ward or officer.
