GSTIN Full Form & Structure

GSTIN stands for Goods and Services Tax Identification Number. It is a 15-character alphanumeric code assigned to every GST-registered business in India. Example: 27AABCU9603R1ZX

Step 3: Company Ka Actual Naam Kaise Pata Kare

GSTIN se directly company ka naam format mein encode nahi hota. Naam ke liye 2 official options hain:

1. GST Portal: gst.gov.in/searchtaxpayer → "Search Taxpayer" → Enter GSTIN → Company name, registration date, status sab milega.
2. Invoice Verification: GST-registered sellers are legally required to print their registered business name on invoices. If the name on invoice doesn't match the GST portal — it could be fraud.

Fake GSTIN Se Kaise Bachein

Common fraud patterns in Indian business:

• GSTIN ke 14th character mein 'Z' ke alawa kuch aur hona — invalid
• GSTIN sirf 14 ya 16 characters ka hona — invalid
• State code aur company address ka mismatch — suspicious
• GSTIN ka GST portal pe exist na karna — definitely fake

Character 13: Entity Number

This digit (1–9 or A–Z) tells you how many GST registrations the business has in that state. Most businesses have '1'. If you see '2' or '3', the company has multiple business verticals registered separately in the same state.

Character 15: Check Digit

The last character is a check digit computed using a MOD-36 algorithm (similar to Luhn's algorithm). If this fails validation, the entire GSTIN is mathematically invalid — regardless of how legitimate it looks.
