Whether you're starting a new business, crossing the turnover threshold, or expanding to a new state, SetupFiling.in helps you apply for a new GST number online — with expert-verified documentation, ARN tracking, and dedicated support until your GSTIN is active.
A GST number, or GSTIN (Goods and Services Tax Identification Number), is a unique 15-digit identifier issued to every business registered under GST in India. Applying for a new GST number is the process of registering your business — whether it's a fresh startup, a business that has crossed the mandatory turnover threshold, or an existing business expanding into a new state — with the GST department to legally collect and remit tax, issue GST-compliant invoices, and claim Input Tax Credit.
Our team of Chartered Accountants and Company Secretaries with 15+ years of experience handles the entire application through our complete GST registration service, preparing your documents, filing the application, tracking your ARN, and delivering your GST Registration Certificate along with portal login access.
Every GSTIN follows a fixed 15-character format once your new GST number is allotted.
| Position | Represents |
|---|---|
| Digits 1–2 | State code as per the Indian Census (e.g., 07 for Delhi, 27 for Maharashtra) |
| Digits 3–12 | PAN number of the business or individual applying for GST registration |
| Digit 13 | Entity number of the same PAN holder registered within the state |
| Digit 14 | Default value "Z" (reserved for future use) |
| Digit 15 | Checksum digit for verification of the GSTIN |
Businesses with turnover above ₹40 lakh (₹20 lakh for services, lower in special category states), inter-state suppliers, e-commerce sellers, exporters, casual taxable persons, and businesses expanding to a new state must apply for a new GSTIN.
Legal recognition as a supplier, eligibility to claim Input Tax Credit, ability to sell on e-commerce platforms, seamless inter-state trade, easier access to business loans, and stronger credibility with vendors and clients.
If you're expanding operations to a new state, you need a separate GSTIN for that state, even if your PAN and business remain the same.
If your business details have changed, explore updating details through GST amendment instead of applying fresh, or get help with GSTR-3B filing assistance for ongoing compliance.

The standard threshold is ₹40 lakh annual turnover for goods suppliers and ₹20 lakh for service providers, with lower limits of ₹20 lakh and ₹10 lakh respectively in special category states.
You need PAN, Aadhaar, a passport-size photo, business address proof, and bank account details. Companies and LLPs additionally need incorporation documents and a Digital Signature Certificate.
