GST State Code 13 — Nagaland

How to Read a GSTIN Starting With 13

A GSTIN is 15 characters, and the state code is only the first two. Here is what each part of a Nagaland GSTIN carries:

Position	Value	Meaning
1–2	13	State code — Nagaland. This is the part that identifies where the registration sits.
3–12	PAN	The 10-character PAN of the business or person registered.
13	1–9, A–Z	How many registrations that PAN holds in Nagaland. Usually 1.
14	Z	Fixed. Always Z in a valid GSTIN.
15	check digit	A checksum over the first 14 characters. This is what catches a typo.

Two GSTINs beginning 13 therefore belong to two different businesses registered in Nagaland — the state code alone never identifies a company. To find out who a number belongs to, look up the GSTIN.

Does a Supply From Nagaland Attract CGST + SGST or IGST?

The state code is what decides this, and getting it wrong is one of the most common invoicing errors.

• Buyer also in Nagaland (place of supply code 13) — the supply is intra-state. Charge CGST + SGST, split equally.
• Buyer in any other state or UT — the supply is inter-state. Charge IGST at the full rate instead.

Compare the first two digits of your GSTIN with the first two of the buyer's and the answer follows. Our GST calculator works out the split for you, and place of supply explains the cases where the buyer's address is not the deciding factor.
