How to Read a GSTIN Starting With 11

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

PositionValueMeaning
1–211State code — Sikkim. This is the part that identifies where the registration sits.
3–12PANThe 10-character PAN of the business or person registered.
131–9, A–ZHow many registrations that PAN holds in Sikkim. Usually 1.
14ZFixed. Always Z in a valid GSTIN.
15check digitA checksum over the first 14 characters. This is what catches a typo.

Two GSTINs beginning 11 therefore belong to two different businesses registered in Sikkim — the state code alone never identifies a company. To find out who a number belongs to, look up the GSTIN.

Does a Supply From Sikkim 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 Sikkim (place of supply code 11) — 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.

Frequently Asked Questions

Which state is GST state code 11?

GST state code 11 is Sikkim. Every GSTIN whose first two digits are 11 belongs to a taxpayer registered in Sikkim. Its ISO 3166-2:IN alpha code is SK.

What does a GSTIN starting with 11 mean?

The first two digits of a GSTIN are the state code, so a GSTIN starting 11 means the taxpayer holds that registration in Sikkim. The next ten characters are the PAN, the thirteenth is the registration count for that PAN in the state, the fourteenth is always Z, and the fifteenth is a check digit.

Is a supply from Sikkim charged CGST and SGST or IGST?

If the place of supply is also in Sikkim — that is, the buyer's state code is also 11 — the supply is intra-state and attracts CGST plus SGST. If the buyer is in any other state or union territory, it is inter-state and attracts IGST instead.
