New registration with same e-mail id, mobile no and pan no

A person supplying goods or services from different states is mandated to take different GSTIN for each state (which would be based on a single PAN).
 
Also a person who has different verticals of business within the same state can choose to have different GSTIN for each vertical (and these would again be based on a single PAN)

Important thing to note here is each GSTIN whether in different states or in the same state (for different verticals) would be treated as a separate entity under the GST law, i.e. supply within the verticals or within different units in other states would be subject to GST.
