All the business entities registering under GST will be provided a unique identification number known as GSTIN or GST Identification Number.Currently any dealer registered under state VAT law has a unique TIN number assigned to him by state tax authorities. Similarly, service tax registration number is assigned to a service provider by Central Board of Excise and Customs (CBEC). Under GST regime, all these parties will come under one single authority and the different identification numbers will be replaced by a single type of registration number for everyone (GSTIN). This will ensure better administration by the authority and greater compliance by taxpayers and hopefully improve tax collection.

• Every taxpayer will be assigned a state-wise PAN-based Goods and Services Taxpayer Identification Number (GSTIN) which will be 15 digit long.
• The first two digits of GSTIN will represent the state code according to indian census 2011. Each state has a unique two digit code like “27” for Maharashtra and “10” for Bihar.
• The next ten digits of GSTIN will be the PAN number of the taxpayer.
• 13th digit indicates the number of registrations an entity has within a state for the same PAN. 
  
  It will be an alpha-numeric number (first 1-9 and then A-Z) and will be assigned on the basis of number of registrations a legal entity (having the same PAN) has within one state.
