GST verification: Ensuring authenticity and compliance with GSTIN

The Ultimate Guide to GST Verification Online

Goods and Services Tax, popularly known as GST, was introduced in India in July 2017 to streamline the indirect tax system across the country. GST was launched to enhance transparency, eliminate cascading tax (tax on tax), and facilitate ease of doing business. Businesses and individuals registered under GST are allotted a 15-digit PAN-based unique identification number known as GSTIN. GST verification is a must to ensure the integrity and authenticity of the quoted GST number. GST verification is important for consumers, businesses, and individuals as it ensures transparency, prevents fraud, and promotes wider compliance with GST regulations.

We will explore the concept of GST verification, its significance, and the methods employed for verification in this article. 

Understanding GSTIN and its format

Goods and Services Tax Identification Number (GSTIN) is a unique identifier granted to firms and professionals registered under the Goods and Services Tax (GST) regime in India. 

GSTIN is a 15-digit alphanumeric code used for several GST-related procedures, including submitting returns, obtaining input tax credits, and making payments. The GSTIN identifies the taxpayer and allows the GST system to track their transactions.

The first two digits of the GSTIN denote the state code, the next 10 digits signify the PAN number of the business or the professional, followed by the entity code and the digit check. 

All businesses and professionals operating in India are required to obtain GSTIN to comply with India’s taxation laws. Since the introduction of GST in India in 2017, obtaining a GSTIN has been made mandatory. 

Decoding the GSTIN structure

Let us understand the GSTIN structure with the help of an example. For instance, the GSTIN number of a business is 07AAECM9636P1ZP. The table below will break down the alphanumeric GSTIN number for you.  


Character Meaning 
First two digits i.e. 07State Code 
Next 10 digits i.e. AAECM9636PPAN allotted to the business
13th digiti.e. 1The number of registrations in a state
14th digiti.e. Z Default character
15th digiti.e. PChecksum digit or number
  1. The 13th digit denotes the registrations in the state. It’s a combination numeric/alphabetic code, with digits 0 through 9 preceding the letters A through Z.
  2. The 14th digit is a default determined by the type of company. The letter Z is used to indicate a typical taxpayer.
  3. The GST department grants a GST Number to an NRTP (non-resident taxable person) who doesn’t have a Permanent Account Number. Therefore, the following 10 digits of GSTIN would be the foreign government’s tax identification number.

The GSTIN format will help you identify the state in which the business is registered and the type of business, and will also help you with GST verification. This reduces your chances of getting involved in a fraudulent transaction. 

Importance of GST verification

GST registration is a must for all businesses or professionals functioning in India. However, some businesses or professionals quote a legitimate-looking GSTIN in their invoices to avoid paying taxes without actual GST registration. Quoting a false GSTIN number is a case of tax evasion and is akin to theft. 

GST verification comes into play here as it will help you verify the legitimacy of the GSTIN quoted in the invoice or on the shop front. 

Additionally, GST verification is mandatory for businesses. Professionals and business owners are required to verify the GST numbers of their suppliers and customers before making any transactions with them. 

GST verification will ensure that businesses are dealing with registered taxpayers and they can claim input tax credits on their purchases.

The verification process plays an important role in preventing GST-related frauds and errors right at the beginning. Verification also helps to ensure that the business is legitimate. In the absence of proper GST verification, fraudsters can easily bypass the system, causing huge losses to the exchequer.
