what is gst registration number

A GST registration number, also known as GSTIN (Goods and Services Tax Identification Number), is a unique 15-digit identification number assigned to every taxpayer registered under the Goods and Services Tax (GST) regime. It is a state-wise and PAN-based number that is used for compliance and administration purposes. The GSTIN is obtained through the GST registration process, which is free of cost, and is critical for businesses with an annual turnover exceeding a certain threshold to avail various benefits available under the GST regime. Once the application is approved by the GST officer, a unique GSTIN is allocated to the dealer. The format of the GSTIN includes state-wise and PAN-based identification, and it is essential for businesses to file GST returns and pay GST liability if applicable. The process of obtaining a GSTIN involves providing necessary documents, verification by the GST officer, and receiving the unique GSTIN upon approval of the application. Businesses can apply for GST registration and obtain a GSTIN online through the official GST portal, and once approved, they will receive a notification via email and text message, along with a temporary username and password for login. After the approval, businesses can download their registration certificate from the official portal. It is important to note that the GSTIN is different from the Goods and Service Tax Network (GSTN), which is an organization that manages the entire IT system of the GST portal.
