What is GSTIN Number?

A GSTIN (Goods and Services Tax Identification Number) is basically your business's identity number in the GST system.
GSTIN Number Format


  • GSTIN Structure Breakdown
  • First 2 digits - State code
  • Next 10 digits - PAN of the taxpayer
  • 13th digit - Entity number under same PAN
  • 14th digit - Default “Z”
  • 15th digit - Checksum digit
This standardized structure enables system-driven validation across GST systems, ERPs like SAP, and compliance tools.

Why is GSTIN Validation Required?

GSTIN validation is required for various purpose some of which are as below -
  1. Customer onboarding i.e. while creating customer code in the ERP or accounting system of a company
  2. Vendor onboarding i.e. while creating vendor code in the ERP or accounting system of a company
  3. To identify GST taxpayer type - regular, composite, ISD, SEZ, etc. It is very critical to identify taxpayer type as GST compliance requirement for each type of taxpayer is different.
  4. To do correct Input Tax reconciliation (ITC) - it is often required by business to verify GST number of the vendor while claiming rightful ITC during monthly or quarterly GST return filling
  5. To raise the right tax invoice to the customer it is very important to capture & validate GSTIN of the customer on real-time basis specially for e-Commerce or online business
Sepfust also provides APIs to companies for GSTIN validation. Sepfust also provides GSTIN validation integration program with customer & vendor master for SAP & Oracle ERP.
