1 – 2 = STATE CODE

3 – 12 = PAN NUMBER

13 = Business vertical number in the same state. A total of 35 business verticals of the same legal entity can be registered within the same state.

Let us understand this with an example:
Suppose a legal entity with single registration within a state will have “1” as the 13th digit of the GSTN.
If the same legal entity goes for a second registration for a second business vertical in the same state, the 13th digit of GSTIN assigned to the second entity would be “2”.
