GSTIN Checker & GST Notice Verification

Q: How do you verify a GSTIN?

Paste any 15-digit GSTIN into the Universal Scanner and ScamShield AI checks it against the official GST registry in real time. You get back the registration status (active, cancelled or suspended), the registration date, the legal and trade name, and recent filing history, so you know whether a vendor is genuine before you transact. A verdict returns in under 3 seconds.

Q: Can you tell if a GST demand notice is fake?

Yes. Upload the notice and ScamShield AI checks the document reference number against valid CBIC and CBDT formats, verifies that any links point to the official gst.gov.in and not a lookalike domain, and flags coercive deadlines such as 'your GSTIN will be cancelled in 24 hours' that genuine departments do not use. You get a risk score with plain-English reasons.

Q: Do you also check income-tax letters?

Yes. Income-tax correspondence and CBDT letters are checked the same way as GST notices: the reference-number format, the sender and any linked domain, and the tone of the demand are all analysed for signs of impersonation. Nothing you upload is stored beyond the verdict.

GSTIN registry lookup and GST notice verification are available on both the Starter and Professional plans through the Universal Scanner. Start with a 30-day free trial. No card required.

Check a GSTIN's structure — free, instant, in your browser

15 characters. We validate the state code, the embedded PAN and the official check digit — entirely in your browser. Nothing you type is sent, stored, or logged.

A new vendor sends an invoice with a GSTIN that looks perfectly valid. Weeks later your input-tax credit is reversed, because the registration was cancelled or the number never belonged to that firm. Separately, a threatening “GST demand notice” lands in your inbox warning that your registration will be cancelled within 24 hours unless you pay. Both are common ways Indian SMEs lose money and trigger real compliance trouble.

ScamShield AI checks the facts a busy accounts team cannot verify at a glance. It looks up the GSTIN against the official registry, and it reads any demand notice or income-tax letter for the tell-tale signs of a forgery, before you pay or transact.

What it checks on every GSTIN and notice

Live GSTIN registry lookup

Paste a 15-digit GSTIN and it is verified against the official GST registry in real time: registration status (active, cancelled or suspended), registration date, legal and trade name, and recent filing history.

Fake GST demand notices

Upload a demand notice and ScamShield AI checks the document reference number against valid formats and flags coercive deadlines like “GSTIN will be cancelled in 24 hours” that genuine departments never use.

Income-tax & CBDT letter checks

Income-tax correspondence is read the same way: the CBDT and CBIC reference formats, the sender, and the tone of the demand are all analysed for forged reference numbers and signs of impersonation.

Spoofed government domains

Any link in the notice is checked against the official gst.gov.in. Lookalikes such as gst-verify-portal.in that harvest payments and credentials are caught before your team clicks.

The notice links to a spoofed domain, gst-verify-portal.in, not the official gst.gov.in.
The document reference number does not match a valid CBIC format.
A coercive deadline, “GSTIN will be cancelled in 24 hours,” is a known impersonation tactic.
