Every bill you get from the shopkeeper had to be associated with GST number inorder to charge you the service tax . But I have noticed in few instances where GSTIN number is shown in the bill but it does not seems authentic. So I had to find ways to verify this. All I did was to go to GST website . Key in the GSTIN number that’s in the bill and verify if it’s really registered and compare the same name in the bill.
Steps to do this is shown in the video below. Please watch it
