1. Find GSTIN (Tool 1)
The GSTIN finder is a simple online tool to verify a business’s 15-digit Goods and Services Tax Identification number. Just enter a number, and it shows details like business name, address, state code, and registration status from the official record. This quick check GSTIN confirms if the supplier or customer is genuine and active under GST laws.
Composition of GSTIN:
| Section | Description |
| First 2 digits – State Code | Represents the state or union territory |
| Next 10 digits – PAN Number | These digits are the same as the business entity’s Permanent Account Number. |
| 13th digit – Entity Code | This digit shows how many GST registrations the same business (same PAN) has in that state. |
| 14th digit – Default “Z” | Reserved for future use (currently always Z). |
| 15th digit – Checksum Digit | Used for error detection and validation. |
