Understanding Your GSTIN

Your GSTIN is a unique 15-digit alphanumeric code. Here is what it means:

• First 2 digits: State code (e.g., 36 = Telangana, 27 = Maharashtra)

• Next 10 digits: PAN of the business entity

• 13th digit: Entity number (how many GSTINs this PAN has in the same state)

• 14th digit: Always 'Z' (default)

• 15th digit: Checksum digit

What to Do After Getting Your GSTIN

• Update all invoices, letterheads, and business documents with your GSTIN

• Set up GST-compliant accounting software (Tally, Zoho Books, etc.)

• File your first GSTR-1 and GSTR-3B for the month in which you registered

• Display your GSTIN prominently at your place of business (legally required)
