Ever wondered how a 15-digit number could unlock a world of ease and efficiency, especially within India's tax landscape? From aiding the timely filing of taxes to availing loans, this magical number has revolutionised the way businesses operate in our country! Learn why the GSTIN number is viewed as a game-changer by entrepreneurs and companies alike. This blog shall highlight the GSTIN full form, its format and importance in detail.
What is GSTIN & Why Do Businesses Need it?

The GSTIN, or Goods and Services Tax Identification Number, is a 15-digit number that single-handedly simplifies India's entire tax landscape. This unique identifier is assigned to each taxpayer, including:
-
Businesses
-
Dealers
-
Suppliers
All who are registered under the Goods and Services Tax (GST) system.
The best part is that registering for GST and subsequently obtaining a GSTIN is free. This makes it a win-win situation for businesses.
The GSTIN is required to smoothly and legally run a business in India, given that the entity’s annual turnover is over ₹40 lakh (or ₹10 lakh in case of Northeast states). Registering for GST and getting a GSTIN allows one to avoid fines/penalties. Highlighted below are the reasons for getting the GSTIN:
1. GST Return Filling
One needs the GST number in order to file GST returns. This is a necessary step for each GST-registered individual, whether or not there’s relevant business-related activity taking place/tax due.
2. Input Tax Credit Claim
You need the GST number to claim back the GST you've paid upon making business-related purchases. Note that the input tax credit claim can only be made if the supplier records the invoice details on the GST portal.
3. Minimised Chances of Fines
If you have the GST number, you can avoid fines even for not following certain GST rules. For example, if you’re required to register for GST but haven’t done so, a 10% fine of the tax owed/₹10,000 (the higher amount) is otherwise levied. Not possessing a GST number could also negatively impact your chances of getting a Business Loan.
Format of the GST Number
A GST number comprises 15 digits. An example of a GST number would be 19 ABCDE9999F1Z8. Here’s what the digits denote:
-
The first 2 digits are the state code; for West Bengal, it would be 19.
-
The following 10 digits correspond with the PAN number of the respective business.
-
The 13th number indicates the number of firms that are registered under this GST.
-
Lastly, the final 2 digits are a unique combination assigned to the concerned firm.
