GST State Code 13 — Nagaland
GST state code 13 is the code for Nagaland. Any GSTIN beginning with “13” was issued to a business registered in Nagaland under the Goods and Services Tax.
Where the code sits inside a GSTIN
A GSTIN is exactly 15 characters. The first two digits are the state code — 13 for Nagaland. Characters 3 to 12 are the PAN of the registered business, character 13 counts that PAN's registrations within the state (1–9, then A–Z), character 14 is the letter “Z” by default, and character 15 is a check digit computed from the first fourteen.
Worked example (fictitious PAN, valid structure and check digit):
13ABCDE1234F1Z9
Here 13ABCDE1234F1Z9 reads as: registered in Nagaland, PAN ABCDE1234F, first registration for that PAN in the state, with a mathematically valid check digit. Do not invoice against example numbers — always verify the real GSTIN first.
GST administration in Nagaland
Nagaland, capital Kohima with its commercial hub at Dimapur, comes under the Dimapur Commissionerate of the CBIC Guwahati zone. Dimapur's position as the railhead gateway for the state concentrates most GST registrations there — wholesale distribution, construction and transport — while the Hornbill Festival season drives a visible hospitality trade.

Frequently asked questions
Which state has GST state code 13?
GST state code 13 belongs to Nagaland. Every GSTIN issued to a business registered in Nagaland begins with the digits 13.
Where does the state code appear in a Nagaland GSTIN?
The state code is always the first two characters of the 15-character GSTIN. If a GSTIN starts with 13, the registration was issued in Nagaland. Characters 3–12 are the PAN of the business, character 13 is the entity number, character 14 is always “Z”, and character 15 is a checksum.
Is the GST state code the same as the state's vehicle or census code?
No. GST state codes follow the Indian Census 2011 numbering adopted by GSTN, which is different from RTO vehicle registration codes. Always use the two-digit GST code when filing returns or raising invoices.
What does it mean if my supplier's GSTIN does not start with 13 but they claim to operate from Nagaland?
It usually means the supplier is registered in a different state and supplies to Nagaland inter-state (IGST applies instead of CGST+SGST). If they invoice you claiming local registration with a mismatched state code, verify the GSTIN before paying — the place of supply affects your input tax credit.
Can one business have more than one GSTIN in Nagaland?
Yes. A business with multiple verticals or units in Nagaland can hold multiple GSTINs, all starting with 13 and sharing the same PAN — only the 13th character (entity number) differs. Search by PAN on GST Search to see every registration held by one PAN.
