Every valid GSTIN follows a fixed 15-character structure. If a number doesn't match this pattern, it isn't a valid GSTIN. Knowing the structure lets you spot an obviously fake GSTIN instantly.
For a valid, registered GSTIN, the result shows:
If the number has an invalid format or check digit, the tool flags it immediately – a strong signal to double-check with your vendor before proceeding.
Verifying a GSTIN takes three steps:
A GSTIN (Goods and Services Tax Identification Number) is a unique 15-character, PAN-based registration number issued to every business or individual registered under India's GST law. A taxpayer must obtain a separate GSTIN for each state or Union Territory in which they operate.
Before GST, businesses held separate registration numbers for VAT, Service Tax and Excise. GST replaced all of these with one standard number – the GSTIN – making it far easier to verify a business's tax registration from a single lookup.
You must register for GST once your annual aggregate turnover crosses ₹40 lakh for suppliers of goods or ₹20 lakh for suppliers of services (₹20 lakh and ₹10 lakh respectively in special category states). Some businesses, such as inter-state suppliers and e-commerce sellers, must register regardless of turnover.
GSTIN data is public, so verifying a number costs nothing. Skipping the check, however, can cost you input tax credit, penalties and a failed tender bid. Here's why a quick GST search matters before you book an invoice or sign a contract:
GST provisions directly affect tender pricing, eligibility and compliance. Here are the key rules bidders should know:
Where GST applies to tender document fees, it is typically charged at 18%. Whether a fee is taxable depends on who charges it and the applicable exemption notifications, so check the NIT for how the fee is to be paid.
Since 22 September 2025 (GST 2.0), the concessional 12% rate on works contracts has been withdrawn. Works contracts for Central or State Governments, local authorities and government entities, including earthwork contracts and public infrastructure such as roads, bridges and railways, now attract GST at 18%. For work that spans the change, the applicable rate depends on when the work was done, invoiced and paid for (Section 14 of the CGST Act), so re-check pricing on any bid prepared under the old rates.
Bidders in most government and public-sector tenders must hold a valid GSTIN and PAN, subject to the tender conditions and statutory exemptions.
For specific transactions notified under GST, the recipient or project authority pays the GST under the Reverse Charge Mechanism instead of the supplier.
Quote the basic price and the applicable GST separately, unless the Notice Inviting Tender (NIT) specifically asks for a GST-inclusive price.
GST rates, exemptions, eligibility and tax responsibilities vary with the type of work, the contracting authority and government notifications. Review the tender's tax and commercial conditions carefully before submitting your financial bid.
The first two digits of a GSTIN show the state or Union Territory where the business is registered. Here is the complete list of GST state codes. Code 25 (Daman & Diu) was merged into 26 in 2020; 97 is used for Other Territory and 99 for Centre Jurisdiction.
Yes. GST registration and GSTIN allotment are completely free of cost through the GST portal.
A GSTIN is issued once your GST registration application (Form GST REG-01) is successfully processed and approved by a GST officer.
The four types of GST are CGST, SGST, IGST and UTGST. CGST and SGST apply to intra-state supplies, IGST applies to inter-state supplies, and UTGST applies to supplies within eligible Union Territories.

The 15-digit GST number, or GSTIN, is a unique 15-character code (letters and numbers) issued to every GST-registered business. It contains the state code, the holder's PAN, an entity number, the letter Z by default and a check digit.
A GSTIN must be quoted on invoices, e-way bills, GST returns and official communication with tax authorities. A business that is liable to register must obtain a GSTIN before making taxable supplies.
Yes. A business needs a separate GSTIN for each state or Union Territory it operates in, and may take separate registrations for different business verticals within a state. A GST search returns details only for the specific GSTIN you enter.

This tool searches by GSTIN only. To find a business's GSTIN, ask for their GST registration certificate or check the GSTIN printed on their invoice, then verify it here.
This tool verifies one GSTIN at a time. Every GSTIN contains the holder's PAN in characters 3 to 12, so you can confirm that a GSTIN belongs to a given PAN by comparing those characters.
Enter the GSTIN into the search tool above. Valid, registered numbers return full business details and their current status; numbers with an invalid format or check digit are flagged immediately.
Search the GSTIN. The result includes the principal place of business and any additional places of business registered under that number.
Run the GSTIN through the search tool. The result shows the current status (active, cancelled or suspended) and the cancellation date, if applicable.
Enter the company's GSTIN in the tool above. If it is registered, you will see its current status and full registration details.
