Answer By law4u team

GSTIN means Goods and Services Tax Identification Number. It is a unique fifteen digit number given to every business or person who is registered under the Goods and Services Tax system in India. GSTIN is issued by the government under the provisions of the Central Goods and Services Tax Act, 2017. It is used to identify taxpayers, track tax payments, and manage compliance under GST. The number is based on the PAN of the business along with state code and other digits for identification. Any business that crosses the prescribed turnover limit or falls under compulsory registration categories must obtain GSTIN. GSTIN is required for issuing tax invoices, collecting GST from customers, claiming input tax credit, filing GST returns, and doing interstate business transactions.

Dear Client, GSTIN number is a 15 digit alpha numerical code. It is given to every entity that has registered under the GST regime. It replaced multiple identification numbers like the TIN, Service Tax numbers, etc. The numbers are arranged in systematic order. The first two digits refer to the state code, while the next 10 digits refer to the PAN number of the entity. Additionally, the next two digits serve as a check code. This is a mandatory number given to every entity registered, and these entities need to mandatorily display the same at their place of business. I hope this answer helps. For any further queries, please do not hesitate to contact us. Thank you.
