However, over and above GSTIN, GST Authorities also issue GST Unique ID, which is commonly referred as Unique Identification Number or Unique Identity Number. UIN is a distinct class of GST Registration for foreign diplomatic missions and embassies, which are not liable to taxes in the Indian Territory.

The main purpose of GST UIN is it enables the body to collect tax refund on purchases / inward supplies of goods and services.
