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. But within a State an entity with different branches would have single registration wherein it can declare one place as principal place of business and other branches as additional place of business. However, a business entity having separate business verticals (as defined in section 2 (18) of the CGST Act, 2017) in a state may obtain separate registration for each of its business verticals. Further a unit in SEZ or a SEZ developer needs to necessarily obtain separate registration.

A casual taxable person is one who has a registered business in some State in India, but wants to effect supplies from some other State in which he is not having any fixed place of business. Such person needs to register in the State from where he seeks to supply as a casual taxable person. A non-resident taxable person is one who is a foreigner and occasionally wants to effect taxable supplies from any State in India, and for that he needs GST registration.   

GST law prescribes special procedure for registration, as also for extension of the operation period of such casual or non-resident taxable persons. They have to apply for registration at least five days in advance before making any supply. Also, registration is granted to them or period of operation is extended only after they make advance deposit of the estimated tax liability.

In respect of supplies to some notified agencies of United Nations organisation, multinational financial institutions and other organisations, a centralised unique identification number (UIN) is issued.
