The importance of verifying the authenticity of a GST number cannot be overstated. It goes beyond mere compliance with tax regulations; it safeguards against fraud and ensures the legitimacy of transactions in a digital and interconnected world. In this digital age, where financial transactions are swift and dynamic, verifying a GST number is paramount to secure, transparent, and lawful business interactions.

What is the GST Number?

GSTIN is the GST identification number or GST number. A GSTIN is a 15-digit PAN-based unique identification number allotted to every registered person under GST. As a GST-registered dealer, please verify GST before entering it into your GST Returns.

An individual or entity registered under the Income Tax Act can possess multiple GSTINs, each GSTIN corresponding to the state or Union Territory in which they conduct business operations. The obligation to obtain a GSTIN arises when an individual or entity surpasses the threshold limit for GST registration specified under GST regulations. 

In contrast to the prior indirect tax system, which required separate registration numbers for various laws like Excise, Service Tax, and VAT, GSTIN streamlines the process by providing a single registration number under the GST regime.

Importance of GST Number Verification

  • GSTIN or GST number is public information, and it’s crucial for businesses dealing with GST-registered taxpayers to verify the authenticity of the vendor and the GSTIN or GST number on their invoices.
  • Verifying the GSTIN is essential to prevent the generation of inaccurate invoices and e-invoices, ensure eligibility for genuine input tax credits, and correctly pass on tax credits to the rightful buyers, among other reasons.
  • Accurate GSTIN verification is necessary to avoid potential legal and compliance issues. Incorrect or fraudulent GSTINs can lead to penalties or legal complications for the business issuing the invoice and the recipient.
  • Validating GSTINs is essential for businesses and government authorities to maintain the tax system’s integrity, prevent tax evasion, and ensure that tax credits are correctly accounted for.

GST Identification Number Format

Here’s a breakdown of the components of a GSTIN:

  • The first two characters represent the state code, indicating the state in India where the business is registered.
  • The following ten characters represent the business or individual’s PAN (Permanent Account Number).
  • The thirteenth character is assigned based on a person or business’s number of registrations within a state.
  • The fourteenth character is typically “Z” by default.
  • The fifteenth character is a checksum digit for error detection.
