Verify a GSTINHow to Read a GSTIN Starting With 21
A GSTIN is 15 characters, and the state code is only the first two. Here is what each part of a Odisha GSTIN carries:
| Position | Value | Meaning |
|---|---|---|
| 1–2 | 21 | State code — Odisha. 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 Odisha. 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 21 therefore belong to two different businesses registered in Odisha — the state code alone never identifies a company. To find out who a number belongs to, look up the GSTIN.
Does a Supply From Odisha 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 Odisha (place of supply code 21) — 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.

Which state is GST state code 21?
GST state code 21 is Odisha. Every GSTIN whose first two digits are 21 belongs to a taxpayer registered in Odisha. Its ISO 3166-2:IN alpha code is OD.
What does a GSTIN starting with 21 mean?
The first two digits of a GSTIN are the state code, so a GSTIN starting 21 means the taxpayer holds that registration in Odisha. 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 Odisha charged CGST and SGST or IGST?
If the place of supply is also in Odisha — that is, the buyer's state code is also 21 — 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.
