How to Spot a Fake GST Number and Stay Safe From Scams

Fake GST Number: How to Identify and Avoid Scams

If you’ve ever run into a business that proudly shows off a GST number but something just doesn’t sit right, you might’ve spotted a scam. Sadly, fake GST numbers are becoming common these days. People use them to look legit and cheat honest customers or business owners. Good news, you don’t need to be a tax expert to figure this out. Once you know the basics, catching a fake GST number is easy.

What’s a GST Number?

In simple terms, your GST number (GSTIN) is your business’s ID in the GST world. It’s like how your PAN works for you, but this one’s for your business. It’s made up of 15 digits and yes, each one tells a small story about your business.

PART	WHAT IT SHOWS
First 2 digits	State code (like 27 for Maharashtra, 09 for UP)
Next 10 digits	PAN number of the business
13th digit	Registration number under the same PAN
14th digit	Always “Z”
15th digit	A check code

So if you ever see a GST number that doesn’t fit this format, that’s your first red flag.

What’s a Fake GST Number?

A fake GST number is basically a made up or copied code that doesn’t exist in the government database. People use it to:

1. Issue fake GST bills

2. Collect tax and keep it themselves

3. Pretend they’re a registered business

In short: they’re using it to look legal, but they’re not.

How You Can Identify a Fake GST Number

You don’t need to be a CA or accountant for this. Just follow these simple checks:

Step 1: Count the Characters

Every GSTIN has exactly 15 characters. If it’s shorter or longer, it’s fake.

Step 2: Check the State Code

Each state has a fixed code. Let’s say a seller claims they’re from Gujarat, but their GST number starts with 09, which actually stands for Uttar Pradesh. That’s your clue to double check.

Step 3: Search It Online

Go to the official GST site → click on “Search Taxpayer” → enter the number. If it doesn’t match the business name or says invalid, it’s fake.

Step 4: Check Their Invoice

A proper GST invoice will show:

1. GSTIN of the seller

2. Invoice number & date

3. Tax breakup (CGST, SGST, IGST)

4. A HSN/SAC code

If it looks incomplete or poorly formatted, better double check.

Example

Let’s say you buy electronics from an online seller. They give you a “GST invoice” with a 10% discount and a GST number. You check it on gst.gov.in , and it doesn’t exist. What happened? They collected GST from you, but didn’t pay it to the government. You’ve basically paid extra money for nothing. That’s exactly how these scams work.

You can verify any GSTIN on the official GST portal to confirm if a business is genuine.

How to Protect Yourself from Fake GST Scams

Here are a few simple steps that go a long way:

Always Verify

Before paying or placing a big order, just look up the GSTIN on the portal. Takes 30 seconds.

Ask for a Proper Bill

A genuine business will always give a proper tax invoice. No hesitation, no excuses.

Keep All Proofs

Save every bill or invoice digitally. You’ll thank yourself later if something goes wrong.

Report the Fakes

If you find someone using a fake GSTIN, report them here: CBIC GST Complaint Page. If you find a suspicious GST number, you can report fake GST numbers to CBIC using their online helpdesk portal.
