A GST number is more than a compliance badge. It is what lets you issue tax invoices, collect GST legally, claim Input Tax Credit and sell on most online marketplaces. Many business customers will not deal with a supplier who has no GSTIN, because they cannot claim credit on the purchase. For some businesses it is a legal requirement; for others, it is a growth decision. Either way, getting it right the first time saves weeks of back-and-forth.
Registered buyers need your GSTIN on the invoice to claim credit, so registration opens doors to larger customers.
Once registered, GST paid on purchases can be set off against GST you collect, subject to conditions.
Online platforms typically ask for a GSTIN before they onboard a seller.
A GSTIN on your invoice and name board signals a formal, trackable business to banks and clients.
| Your situation | GST number needed? |
|---|---|
| Supplying goods, turnover above the threshold (commonly ₹40 lakh; lower in some states) | Yes |
| Supplying only services, turnover above the threshold (commonly ₹20 lakh; lower in special category states) | Yes |
| Selling goods to another state | Generally yes, from the first sale |
| Selling through an e-commerce platform | Generally yes, regardless of turnover |
| Paying GST under reverse charge | Yes, in many cases |
| Below the threshold with no special trigger | No, but you can register voluntarily |
Thresholds and conditions are set by the GST Council and can change. Confirm the current position for your business before deciding.
Your GSTIN is not a random number. Every character has a job. Here is how a 15-character GSTIN is built, using a made-up example.
| Position | What it is | Example |
|---|---|---|
| 1–2 | State code | 07 (Delhi) |
| 3–12 | PAN of the business | ABCDE1234F |
| 13 | Number of registrations the PAN holds in that state | 1 |
| 14 | The letter Z (a fixed character) | Z |
| 15 | Check character | 5 |
The example 07ABCDE1234F1Z5 is illustrative and not a real GSTIN.
Because the PAN sits inside the GSTIN, you can often spot a mismatch between a supplier's GSTIN and the PAN on their documents. You can verify any GSTIN through the search taxpayer option on the GST portal.

New GST holders often need a few of these as well:
How do I get a GST number for my business?
Apply for GST Registration on the GST portal with your PAN, Aadhaar, address proof and bank details. After verification you receive an ARN, and once approved the 15-digit GSTIN is issued. SetupFiling.in can handle the whole application for you.
How long does it take to get a GST number?
Approval commonly takes around a week once the application is complete, and can be quicker where Aadhaar authentication goes through smoothly. Queries from the officer can add time, so exact timing varies.
What documents are needed to get a GST number?
PAN, Aadhaar, a photograph, proof of business address such as an electricity bill or rent agreement, a bank statement or cancelled cheque, and entity documents for companies, LLPs and firms.
Is a gst number mandatory for every business?
Not for every business. Registration is required once turnover crosses the threshold, and in some cases from the first rupee, such as inter-state supply of goods, e-commerce selling and reverse-charge liability. Check your facts before deciding.
What does a GST number look like?
It is a 15-character GSTIN: a 2-digit state code, the 10-character PAN, one number showing how many registrations the PAN has in that state, the letter Z, and a check character.
Can I get a GST number without a shop or office?
Yes, in many cases. A home address can be used as the principal place of business with supporting documents and a consent letter from the owner. Virtual office addresses depend on the supporting documents available.
How can I verify a GST number?
Use the search taxpayer option on the GST portal to check the legal name, status and registration date of any GSTIN. It is a good habit before you buy from a new supplier.
What happens after I get my GST number?
Display the GSTIN on your name board, issue tax invoices, furnish bank account details on time and file returns every period, even for months with no sales.
Why do GST applications get rejected?
Common reasons are mismatched names, unclear address proof, missing consent letters and incorrect business details. Replying quickly to an officer's query keeps the application alive.
How much does it cost to get a GST number with SetupFiling.in?
The Silver plan is ₹999, the Gold plan ₹1,999 and the Premium plan ₹3,699. Gold and Premium also include 6 and 12 months of GST return filing.
