GSTIN/GST Number Search Tool Online

 
 

Goods and Services Tax (GST) has simplified the indirect tax system in India, replacing multiple state and central taxes with a unified structure. Every registered business under GST receives a unique GST Identification Number (GSTIN) to conduct tax-compliant operations.

Before starting a new venture or engaging with new suppliers, it is wise to check your business loan eligibility to understand the financing options available for business expansion or working capital needs.

Verifying your business or supplier’s GSTIN ensures legal compliance and smooth business transactions. You can also track compliance when filing your GST return.

What is a GSTIN/GST number?

A GSTIN is a unique 15-digit alphanumeric number issued to businesses registered under GST. It acts as an identity for taxpayers in the GST system and helps the government track tax compliance.

Each GSTIN is linked to a state and a specific business entity. This makes it easy to monitor transactions, prevent tax evasion, and ensure smooth credit claims.

Why is it necessary to verify the GST number?

Verifying a GST Number is crucial for businesses for several reasons:

  • Confirms the legal authenticity of suppliers and clients
  • Ensures eligibility to claim input tax credit
  • Reduces the risk of dealing with fraudulent entities
  • Maintains compliance while filing GST returns

Businesses can learn how to verify GSTIN using the official GST verification tool.

GST identification number format

A GSTIN is structured as a 15-digit alphanumeric code:

Pointers:

  • First 2 digits: State code
  • Next 10 digits: PAN number of the taxpayer
  • 13th digit: Entity code of the same PAN in a state
  • 14th digit: Default ‘Z’
  • 15th digit: Checksum for validation

Understanding the format helps businesses quickly validate GSTINs and identify discrepancies.

Frequently Asked Questions

Can I verify a GST number without the 15-digit GSTIN?

No, you cannot verify a GST number without the complete 15-digit GSTIN. The GSTIN structure is designed to include specific details about the taxpayer:

  • The first two digits represent the state code.
  • The next ten characters are the PAN of the business or individual.
  • The 13th digit indicates the number of registrations within a state.
  • The 14th digit is a default character, currently set to ‘Z’.
  • The 15th digit is a check code used for error detection.

Since the GSTIN is a unique identifier, all 15 characters are essential for accurate verification.

What should I do if my supplier's GSTIN shows as 'Inactive'?

If a supplier’s GSTIN is marked as ‘Inactive’ during verification, it may indicate that their registration has been cancelled or suspended. Here are the steps you should take:

  1. Contact the supplier to confirm the reason for the inactive status.
  2. Request updated GST registration details or proof of compliance.
  3. If the issue is unresolved, escalate the matter within your organisation to determine the next steps.
  4. Report the issue to GST authorities to avoid any liability or complications in claiming Input Tax Credit.

It is crucial to resolve such issues promptly to maintain compliance and avoid potential losses.

Can I find a business's address using their GST number?

Yes, the GSTIN can provide details such as the state in which the business is registered. The first two digits of the GSTIN represent the state code as per the Indian Census 2011. Additionally, the GSTIN is linked to the taxpayer’s registered address, which can be accessed during the verification process. However, for privacy reasons, the complete address may not always be disclosed publicly.

How often is the data in the GST verification tool updated?

The GST verification tool provides real-time data sourced directly from the GST Network (GSTN). This ensures that the information displayed is accurate and up-to-date. It is advisable to rely on official GST portals or authorised verification platforms for the most reliable data.
