GST State Code 16 — Tripura

GST state code 16 is Tripura. Every GSTIN issued in Tripura begins with 16 — the first two characters of a GST number are always the code of the state or union territory that granted the registration.

Example GSTIN registered in Tripura

16AAACR5055K1ZA

Structurally valid and checksum-correct, but illustrative — it is not an issued registration. The highlighted 16 is the state code; the ten characters after it are the holder’s PAN.

Where 16 sits inside a GST number

A GSTIN is 15 characters in a fixed layout. The state code is the part that tells you where the registration was granted, and it is the only part that identifies a place.

Position	Example	What it is
1–2	16	The GST state code — Tripura on this page.
3–12	AAACR5055K	The holder’s PAN, embedded unchanged. This is why one PAN search returns every GSTIN issued to a business across all states.
13	1	Counts registrations held against the same PAN within Tripura. A second registered business vertical in the same state gets 2, and so on.
14	Z	A fixed letter on every regular GSTIN. It carries no information.
15	A	A check digit computed from the first 14 characters. It catches typos — it does not prove the number was ever issued.

Because the checksum algorithm is public, a fabricated number can pass a format check and still be entirely fictitious. Confirming that a 16 GSTIN actually exists means looking it up against the live register. Full breakdown of the format: what a GST number is made of.

CGST + SGST or IGST on a Tripura supply?

Comparing state codes is the first check, and for most supplies it settles the question.

Your GSTIN starts 16, place of supply in Tripura

Intra-state supply. Charge CGST + SGST, split evenly between the centre and the state.

Your GSTIN starts with any other code

Inter-state supply. Charge IGST at the combined rate, which the centre later apportions to the consuming state.

One caveat worth keeping: the place of supply is not always the customer’s billing address. For several categories of service the IGST Act points somewhere else entirely, so treat the state code as the starting point rather than the conclusion.

Cities and districts under code 16

GST state codes are assigned per state or union territory, never per city. Every business registered anywhere in Tripura carries 16 — including Agartala. There is no separate GST code for a city, a district or a commissionerate.

GST state code 16 — common questions

16 is the GST state code for Tripura. Every GSTIN issued by the Tripura GST authorities begins with 16 — for example 16AAACR5055K1ZA. The first two digits of any GSTIN are the code of the state or union territory that granted that registration.

Tripura. A GSTIN beginning 16 was issued in Tripura, which means the registered place of business on that registration is in Tripura.

The GST state code for Tripura is 16. It occupies the first two characters of every GSTIN registered there, whether the business sits in Agartala or anywhere else in the state.

If your own registration also carries state code 16 and the place of supply is in Tripura, the supply is intra-state and attracts CGST plus SGST. If your GSTIN carries any other state code, it is an inter-state supply and attracts IGST instead. Note that the place of supply is not always the customer’s address; the place-of-supply rules in the IGST Act decide it, and for some services they point elsewhere.

Yes. The code is assigned per state or union territory, not per city or district, so a registration in Agartala both begin 16. There is no separate GST code for a city.

No. The state code is fixed inside the GSTIN and cannot be amended. A business moving out of Tripura has to apply for a fresh registration in the new state and surrender or cancel the 16 one. The same PAN then holds two GSTINs with two different state codes, which is normal and expected.

Check a Tripura GST number

A GSTIN starting 16 was issued in Tripura — but the code alone does not tell you whether the registration is still active. Look it up against live government records: registered name, current status, places of business and return filing history.
