EaseValueA wrong GSTIN on an invoice can cost you the input tax credit on it. Paste any GSTIN here and we check it instantly against the official check-digit formula, then decode it: the state of registration, the PAN of the business, what kind of entity it is, and how many registrations the same PAN holds in that state. A GSTIN that fails the check digit is mistyped or fake. For the legal name and whether it is active, open the official Search Taxpayer page — we link straight to it.
How to track it
- Paste the 15-character GSTIN, for example 08ABCDE1234F1Z0.
- Characters 1–2 are the state code, 3–12 are the PAN, 13 is the registration number for that PAN in that state, 14 is usually Z, and 15 is a check character.
- We recompute the check character with the official base-36 formula. If it does not match, the GSTIN is invalid — usually a typo.
- From the PAN we read the entity type: the 4th letter is P for an individual, C for a company, F for a firm or LLP, H for a HUF, T for a trust and so on.
- For the legal name, trade name, status (Active / Cancelled / Suspended) and filing history, open gst.gov.in → Search Taxpayer → Search by GSTIN/UIN.
- Before claiming credit, also confirm the supplier has filed GSTR-1 so the invoice shows up in your GSTR-2B.
Why verifying a GSTIN matters
Input tax credit is allowed only when the supplier’s GSTIN is genuine and active, the supplier reports the invoice in GSTR-1 and it appears in your GSTR-2B. Paying GST to a supplier whose number is mistyped, cancelled or fake means the credit can be denied later, along with interest. A 10-second check before you pay avoids that.
The check digit catches nearly every typing mistake. It does not tell you whether the business is active — a correctly formed GSTIN can still be cancelled or suspended — so for a new or large supplier always confirm the status on the GST portal too.
Frequently asked questions
How do I know if a GSTIN is valid?
A valid GSTIN has 15 characters in the pattern 2 digits + PAN + 1 character + Z + check character, and the last character must match the check digit computed from the first 14. This tool does that check instantly. For the business name and status use Search Taxpayer on gst.gov.in.
Can I find the PAN from a GSTIN?
Yes. Characters 3 to 12 of the GSTIN are the PAN of the business.
What does the 13th character of a GSTIN mean?
It is the number of the registration that PAN holds in that state — 1 for the first, 2 for the second and so on, then A–Z after 9.
Is this tool connected to the GST portal?
No. EaseValue is not affiliated with GSTN. The validation runs in your browser; the legal name and active status are shown only on the official GST portal.
