What is GST verification and why is it important?

GST verification is the process of confirming that a GSTIN (GST Identification Number) is genuine, belongs to the correct business entity, and is currently active in the government's official database. It is important because transacting with a fake or cancelled GSTIN can result in rejected Input Tax Credit (ITC) claims, demand notices, and financial penalties under the CGST Act.

Is GST number verification free?

Yes, LegalDev's GST Verification Tool is completely free. No account creation, no login, and no fees are required. Simply enter the 15-digit GSTIN and get verified results in under 2 seconds.

What information is displayed after GST verification?

After verifying a GSTIN, you can see: legal name of the business, trade name, registered address, date of registration, taxpayer type (Regular, Composition, Non-Resident), constitution of business (Proprietorship, Partnership, Pvt Ltd, etc.), GSTIN status (Active, Cancelled, or Suspended), and state and centre jurisdiction details.

How can I detect a fake GST number?

Red flags for a fake GSTIN include: the portal returning 'No Record Found', business name mismatch between the invoice and verification result, the first 2 digits (state code) not matching the vendor's state, GSTIN status showing Cancelled or Suspended, no return filing history, and the embedded PAN (digits 3–12) not matching the vendor's actual PAN.

What happens if I purchase from a vendor with a cancelled GSTIN?

If you purchase from a vendor with a cancelled GSTIN and claim Input Tax Credit (ITC), the GST department will detect the mismatch in GSTR-2B reconciliation. You may be required to reverse the ITC, pay 18% interest on the amount, and respond to a demand notice. Under Section 16 of the CGST Act, the buyer is responsible for ensuring the supplier is properly registered.

Can I search for a GST number using a PAN number?

Yes. Using the GST portal's 'Search Taxpayer by PAN' option, you can find all GSTINs registered under a specific PAN across all states in India. This is useful when you have only the vendor's PAN and need to find or verify their GSTIN.

Can I search for a GSTIN using a company name?

Yes. LegalDev's 'Name to GST Search' tool allows you to enter a business name and find its associated GSTIN. This is helpful when you only know the company name and need to verify their GST registration before a transaction.

How often should I perform GST verification?

Best practice is to verify GSTIN: during every new vendor onboarding, before every major purchase transaction, during monthly GST reconciliation to check all active vendors, and whenever a vendor changes their business address or structure. A GSTIN can be cancelled at any time, so one-time verification is not sufficient.

What should I do if GST verification shows 'No Record Found'?

First, re-check the GSTIN for typing errors — common mistakes include confusing O with 0 or I with 1. If the result is still 'No Record Found', the GSTIN does not exist in the government database and is fake. Do not proceed with the transaction. You can report fraudulent GSTINs at gst.gov.in/contact.

How does GST verification protect my Input Tax Credit (ITC)?

When you purchase from a vendor with a valid, active GSTIN who files their returns, the GST paid auto-populates in your GSTR-2B, enabling you to claim ITC. If the vendor's GSTIN is fake, cancelled, or they have not filed returns, the ITC will not appear in your GSTR-2B and you will lose that credit. Regular GST verification eliminates this risk entirely.

What is the difference between GST verification and GST registration?

GST registration is a one-time process where a new business registers under GST and receives a GSTIN. GST verification is an ongoing check performed by buyers and businesses to confirm that a given GSTIN is valid, active, and belongs to the correct entity — done repeatedly before transactions or during compliance reviews.

How is LegalDev's GST Verification Tool different from the government portal?

LegalDev's tool fetches data from the same government database but offers a faster, CAPTCHA-free experience with results in under 2 seconds, a mobile-friendly interface, and no login requirement. Additionally, GST Verification, PAN to GST Search, Name to GST Search, and GST Filing Status tools are all available in one place — completely free.

What Is GST Verification — And Why Every GST Registered Business Must Do It

If you are running a business in India, there is one question you cannot afford to skip before every major transaction: Is this GSTIN real and active? Fake GSTIN fraud costs Indian businesses thousands of crores every year. A vendor hands you an invoice, you claim Input Tax Credit (ITC), and months later a demand notice arrives — not at the vendor's door, but yours. The law places the responsibility of due diligence squarely on the buyer.

GST verification is the process of confirming that a GSTIN (Goods and Services Tax Identification Number) is genuine, belongs to the correct business entity, and is currently active in the government's official database. Whether you want to verify GSTIN online, check GST number authenticity before a purchase, or simply perform a routine gst number verification for compliance — the process takes under 2 minutes.

Here is why every business must make GST verification a standard practice:

Protect your ITC: Input Tax Credit is claimable only if your supplier is registered and has filed their gst returns. Transacting with a cancelled or fake GSTIN means your ITC claim will be rejected — and the financial loss is yours.
Avoid demand notices: GST authorities match buyer and seller data through GSTR-2B. Any mismatch triggers scrutiny, interest, and penalties.
Prevent invoice fraud: Fraudsters create invoices with fabricated or slightly altered GSTINs. A quick GST check status catches this instantly.
Stay legally compliant: Section 16 of the CGST Act requires buyers to ensure their supplier is properly registered. Ignorance is not a legal defence.
Sail through audits: Businesses that maintain a habit of GSTIN verification online face far less disruption during GST audits.

LegalDev's free GST Verification Tool at legaldev.in/gst-verification does all of this in under 2 seconds — no login, no fees, completely free.

GSTIN Format — What Each of the 15 Digits Means

Before you even run a gst status check, it helps to understand the GSTIN format itself. Every GSTIN is a 15-character alphanumeric code, and each section has a specific meaning. Knowing this structure lets you spot obvious fakes at a glance.

Digits	Component	Example	What It Represents
1–2	State Code	07	Identifies the state of GST registration (07 = Delhi, 27 = Maharashtra, 08 = Rajasthan)
3–12	PAN Number	AAAAA0000A	The 10-digit PAN of the registered business or individual
13	Entity Number	1	Sequential number for multiple registrations under the same PAN in one state
14	Default 'Z'	Z	Currently always 'Z' — reserved for future use by the government
15	Check Digit	5	Auto-generated checksum used for GSTIN validation

Example: 27AAAAA0000A1Z5 = Maharashtra (27) + PAN (AAAAA0000A) + 1st entity + Z + check digit 5

⚠️ If the first 2 digits do not match the supplier's state, or the embedded PAN differs from their PAN card — you are looking at a tampered or fake GSTIN.

All India State Codes for GSTIN

The state code is the first two digits of every GSTIN. Use this table to cross-check whether the state code matches the supplier's registered address.

Code	State	Code	State
01	Jammu & Kashmir	02	Himachal Pradesh
03	Punjab	04	Chandigarh
05	Uttarakhand	06	Haryana
07	Delhi	08	Rajasthan
09	Uttar Pradesh	10	Bihar
18	Assam	19	West Bengal
20	Jharkhand	21	Odisha
22	Chhattisgarh	23	Madhya Pradesh
24	Gujarat	27	Maharashtra
29	Karnataka	30	Goa
32	Kerala	33	Tamil Nadu
36	Telangana	37	Andhra Pradesh

How to Detect a Fake GSTIN — Red Flags Every Business Should Know

GST invoice fraud is a growing problem in India. Running a proper gst number verification before every transaction is your first line of defence. Here are the key warning signs to watch for:

Red Flag	What It Means
Portal returns 'No Record Found'	The GSTIN does not exist in the government database at all
Status shows Cancelled, Suspended, or Inactive	You cannot claim ITC from this supplier under any circumstance
Business name on invoice doesn't match the portal	Even a single word difference is a strong red flag for document fraud
No return filing history visible on the portal	Supplier is non-compliant — your ITC will be blocked
State code in GSTIN doesn't match supplier's address	Clear state mismatch — a reliable indicator of a fake GSTIN
Embedded PAN in GSTIN differs from PAN on documents	The GSTIN has been tampered with or fabricated
Unrealistically low prices or unusually large discounts	Classic bait used to lure buyers into fraudulent GST transactions

What to Do If You Suspect Fraud

Do not proceed with the transaction until the GSTIN is fully verified and confirmed active
Cross-check the business name, address, and PAN across all documents provided by the supplier
Request the supplier's GST Registration Certificate and compare it with the portal data
For high-value deals, conduct a physical verification of the listed business address
File a complaint on the GST portal under the Grievance section, or contact your jurisdictional CGST/SGST office directly

Frequently Asked Questions

GST Verification – Frequently Asked Questions

Everything you need to know about verifying a GST number online, checking GSTIN status, and staying compliant.

GST verification is the process of confirming that a GSTIN (Goods and Services Tax Identification Number) is genuine, belongs to the correct business entity, and is currently active in the government's official database. Every business needs to verify GSTIN before transactions to protect their Input Tax Credit (ITC), avoid demand notices, and stay compliant under Section 16 of the CGST Act. A one-minute verification can save you from lakhs in losses due to fake or cancelled GSTINs.

Yes, absolutely. LegalDev's GST Verification Tool is 100% free — no account creation, no login, and no hidden charges whatsoever. Just enter the 15-digit GSTIN in the search box and get verified results from the government database in under 2 seconds. You can use it as many times as you need, any time of the day.

After entering a valid GSTIN, you will instantly see the following details:

Legal name and trade name of the business
Registered principal address
Date of GST registration
Taxpayer type — Regular, Composition, or Non-Resident
Constitution of business — Proprietorship, Partnership, Private Limited, LLP, etc.
GSTIN status — Active, Cancelled, or Suspended
State and centre jurisdiction
Nature of business activity

Here are the most common signs that a GSTIN is fake or tampered with:

No Record Found — the GSTIN simply does not exist in the government database
Business name mismatch — the name on the invoice does not match the name shown after verification
State code mismatch — the first 2 digits of the GSTIN do not match the vendor's state
Status is Cancelled or Suspended — you cannot claim ITC from such vendors
PAN mismatch — digits 3 to 12 of the GSTIN do not match the vendor's actual PAN number
No return filing history — the supplier has never filed GST returns

If any of these red flags appear, do not proceed with the transaction until the issue is clarified.

This is a serious compliance risk. Here is what can happen:

The ITC you claimed will be rejected during GSTR-2B reconciliation
You will be required to reverse the entire ITC amount
GST authorities can charge 18% interest on the reversed amount
A demand notice may be issued to your business

Under Section 16 of the CGST Act, the responsibility of verifying supplier registration lies entirely with the buyer. "I didn't know" is not a valid legal defence — so always verify before you transact.

Yes, you can. Using the "Search Taxpayer by PAN" option on the GST portal, you can find all GSTINs registered under a particular PAN — even across multiple states. This comes in handy when a vendor has printed the wrong GSTIN on the invoice, or when you only have their PAN card and need to cross-check their GST registration. LegalDev's PAN to GST tool makes this search even faster.

Yes. LegalDev's Name to GST Search tool lets you enter a business name and find its associated GSTIN instantly. This is especially useful when you are onboarding a new vendor and only have their company name — you can quickly look up their GST registration details without having to ask them for the GSTIN separately.

We recommend verifying GSTINs at these key points:

At vendor onboarding — always verify before adding a new supplier to your books
Before every major purchase — especially for high-value transactions
Monthly, during GST reconciliation — run a check on all active vendors
When a vendor changes their details — address change, business restructuring, etc.

A GSTIN can be cancelled at any time due to non-compliance or voluntary surrender, so verifying once at the beginning is never enough.

Start by double-checking the GSTIN you entered. Common typing errors include confusing the letter "O" with the number "0", or the letter "I" with the number "1". Also make sure it is exactly 15 characters long.

If the result is still "No Record Found" after re-checking, the GSTIN does not exist in the government database — it is fake. Do not carry out any transaction with this vendor. If you suspect deliberate fraud, you can report it at gst.gov.in/contact.

When you purchase from a vendor with a valid, active GSTIN who regularly files their returns, the GST they collect from you reflects in your GSTR-2B automatically — allowing you to claim that ITC without any issues.

However, if the vendor's GSTIN is fake, cancelled, or they have not filed their returns, the ITC will not appear in your GSTR-2B. This means you will lose that tax credit and have to pay that amount out of your own pocket. A quick GST verification before every transaction makes sure this never happens to you.

GST Registration is a one-time process where a business applies to register under GST, submits required documents, and receives a unique 15-digit GSTIN from the government.

GST Verification, on the other hand, is something you do repeatedly — as a buyer or business partner — to confirm that someone else's GSTIN is valid, active, and genuine before entering into a transaction with them. These are two completely separate activities serving different purposes.

Both use the same government GSTIN database, so the data is equally accurate. The difference is in the experience:

No CAPTCHA — LegalDev gives instant results without any CAPTCHA hassle
Speed — results in under 2 seconds vs slower government portal load times
Mobile-friendly — works smoothly on any device, including phones
No login needed — use it as a guest, any time, completely free
All tools in one place — GST Verification, PAN to GST, Name to GST Search, and GST Filing Status are all available together on LegalDev

Conclusion

GST verification is not a one-time formality — it is an ongoing business practice that protects your Input Tax Credit, shields you from fraud, and keeps your compliance record clean. Every vendor onboarding, every large purchase, and every monthly reconciliation should begin with a quick GSTIN verification online.

With LegalDev's free GST Verification Tool, the entire process takes under 2 seconds. From checking GST number authenticity and viewing GST registration status to tracking and detecting fake GSTINs — everything is available in one place, at no cost.
