It follows the principle of ‘One Country One Tax One Market’ where a single tax is applicable on the supply of goods and services right from the manufacturer to the end-user which makes India one unified common market. GST eliminated a number of indirect taxes. It replaced the prevailing VAT system, services tax, customs tax, etc.

What Is GSTIN?
To learn about how to get GST number, it is essential to first understand what is GSTIN. Before GST was introduced, taxpayers used to have two unique identification numbers TIN and service tax registration number. TIN (Tax Information Number) was allotted by the state government and the service tax registration number was allotted by the Central Board of Excise and Custom(CBEC).
GSTIN or GST Number replaced these two numbers and all the registered taxpayers were shifted to a single platform. GSTIN is GST Identification Number that is allocated to the registered manufacturers, service providers, and business dealers by the Central Government.
