GST Registration Number will be 15 digits- PAN based number- called GSTIN, as under:
- The first two digits of this number will represent the state code
 - The next ten digits will be the PAN number of the taxpayer
 - The thirteenth digit will be assigned based on the number of registrations within a state
 - The fourteenth digit will be Z by default
 - The last digit will be for check code
 - Registration under GST is not tax specific, which means that there is single registration for all the taxes i.e. CGST, SGST/UTGST, IGST and cesses.
 - A given PAN based legal entity would have one GSTIN per State, that means a business entity having its branches in multiple States will have to take separate State wise registration for the branches in different States.
