On this page, you can verify any GSTIN online for free — no login, no captcha, no account required. Just enter the 15-digit GST number and get the full details instantly.
What Is GST Verification?
GST verification is the process of checking whether a GSTIN (GST Identification Number) is valid, active, and registered under the official GST database maintained by the Government of India.
When you verify a GSTIN, you can confirm:
- Whether the GST number exists in the government database
- Whether the registration is active, cancelled, or suspended
- Legal name and trade name of the registered business
- State from which the business is registered
- Type of taxpayer — regular, composition, or casual
- Nature of business activities
- Date of GST registration
- Principal and additional places of business
This information is public. Every GST-registered business in India has its GSTIN details accessible to anyone who wants to verify them.
What Is a GSTIN?
GSTIN stands for Goods and Services Tax Identification Number. It is a unique 15-digit alphanumeric number assigned to every business or individual registered under the GST Act in India. A business operating from multiple states will have a separate GSTIN for each state.
GSTIN Format Breakdown
27AAPFU0939F1ZV
27 → State Code (Maharashtra)
AAPFU0939F → PAN of Entity
1 → Entity Number
Z → Default Character
V → Check Digit
⚠ Invalid on Face: If a GSTIN does not follow this exact 15-character structure, it is invalid — and you should not accept any invoice carrying it.
Why GST Verification Is Important for Every Business
A lot of businesses assume that if a vendor gives them a GSTIN on an invoice, it must be genuine. That assumption can be expensive. Here are the real risks of not verifying a GSTIN:
Risk 1
Blocked Input Tax Credit
ITC from cancelled, suspended, or fake GSTINs gets rejected or reversed during GST audit.
Risk 2
Fake Invoice Fraud
Fraudsters circulate invoices with fabricated GSTINs. If your business unknowingly joins the chain, you become liable.
Risk 3
Invalid Invoices
A tax invoice with an incorrect or inactive GSTIN is not valid under GST law and causes compliance issues.
Risk 4
E-Invoice Failures
The GST portal validates GSTIN during e-invoice and e-way bill generation. Wrong GSTIN causes rejections.
Risk 5
GST Audit Risk
A large portion of inactive vendor GSTINs raises red flags during audits and triggers detailed scrutiny.
Verifying every new vendor's GSTIN takes 10 seconds. The risk of skipping it is far greater.

How to Spot a Fake GSTIN Without a Tool
Even before running a search, you can do a basic manual check of any GSTIN:
Check 1 — Length
A valid GSTIN is exactly 15 characters. Anything shorter or longer is invalid.
Check 2 — State Code
First 2 digits must match the supplier's state. Gujarat = 24, Delhi = 07, Maharashtra = 27.
Check 3 — PAN Match
Characters 3–12 should match the business PAN. Cross-check if vendor shared PAN separately.
Check 4 — Position 14
The 14th character in every valid GSTIN is always the letter "Z". Anything else is invalid.
Check 5 — Run the Tool
If any of the above raise doubt, run the GSTIN through the verification tool. It takes 5 seconds.

Frequently Asked Questions (FAQ)
Is GST verification free?
Yes. Verifying a GSTIN using the tool on GSTFilling.co is completely free. No login, no charges, and no limit on the number of searches.
Can I verify someone else's GSTIN?
Yes. GSTIN details are publicly available information under GST law. Any person or business can verify any GSTIN at any time.
What details can I get from GST verification?
You can get the business name (legal and trade), registration status, taxpayer type, business constitution, date of registration, state of jurisdiction, principal place of business, and nature of business activities.
What if a GSTIN shows as "Cancelled"?
Do not accept an invoice from a business with a cancelled GSTIN. Such invoices are not valid tax invoices and any ITC claimed on them will be rejected or reversed.
Can I find a business's GSTIN using just their name?
Yes. You can search for GSTINs by business name through the GST portal's "Search by Name" feature. However, it requires you to know the state the business is registered in.
Can one PAN have multiple GSTINs?
Yes. A business operating from multiple states must register separately in each state, resulting in separate GSTINs for each. All of them will share the same PAN in characters 3–12 of the GSTIN.
What is the difference between GST verification and GST ARN status check?
GST verification checks the registration details and current status of a GSTIN (is this business registered and active?). GST ARN status check tracks the progress of a GST registration application (has my application been approved yet?). These are two separate tools for two different purposes.
What does "Composition Taxpayer" mean in GSTIN details?
A Composition taxpayer is a small business that has opted for the GST Composition Scheme — they pay tax at a flat rate and cannot charge GST on their invoices. If your supplier is a Composition taxpayer, you cannot claim ITC on purchases from them.
How do I check if a GST number is real or fake instantly?
Enter it in the GST Verification tool on GSTFilling.co. If it does not appear in the database or shows as cancelled/inactive, the invoice is not valid for ITC purposes.
Is it mandatory to verify GSTIN before claiming ITC?
There is no legal mandate that you must run a verification check, but GST law holds the buyer responsible for ensuring that ITC is claimed only from valid, active, and compliant suppliers. Verification is the most practical way to protect that claim.
Conclusion
GST verification is one of the simplest risk management steps a business can take. It costs nothing, takes under 10 seconds, and can save you from blocked ITC, fake invoice liability, and GST compliance issues that are far more expensive to resolve.
Whether you are onboarding a new vendor, verifying a supplier's invoice, or just doing routine due diligence — the GST Verification tool on GSTFilling.co gives you instant, accurate GSTIN details with no login and no hassle.
