GST Number Search Tool - GSTIN Verification Online

TranZact's GST number search tool offers a convenient and cost-free way to perform a GSTIN verification. Our tool allows you to effortlessly conduct a GSTIN search with just one click. With our GSTIN search tool, you can easily verify your GST number and conduct GSTIN verification.

Verifying a registered taxpayer's validity using their GST Search number is important. Through the GSTIN search tool on our website, you can quickly identify a fake and an invalid taxpayer. You will be able to receive the proper input tax credit with GST status verification, which cannot be verified if the GST number is incorrect. The GSTIN search toolbar or GST number check from TranZact is a user-friendly tool for a hassle-free experience. Checking a taxpayer's GST number is essential to ensuring their legitimacy, which helps to ensure that the tax collected moves through the GST supply chain and that cascading of the tax impact is prevented.

What Is the GST Identification Number (GSTIN)/GST Number?

GSTIN or Goods and Services Tax Identification number is a 15-digit alphanumeric code to identify every taxpayer registered under Goods and Services Tax (GST).

It is a PAN-based unique number that helps to track a registered taxpayer. In addition to the GSTIN, a GST taxpayer gets a GST registration certificate.

Thus, your GSTIN represents you under the GST tax regime. You can even have multiple GST numbers. It depends on the states or union territories where you operate your business.

The previous tax regime required multiple registration numbers like VAT, Service Tax, and Excise. But, things are no longer complicated because GSTIN has replaced the other registration numbers.

You have to register yourself under GST on crossing a threshold limit of income.

Why is it Important to Verify GSTIN or GST Number?

GST identification number search and verification is crucial as it helps you to check the authenticity of a taxpayer. That's what makes it so indispensable for businesses.

You can check whether your vendors are authentic taxpayers before signing a contract. That will help you do business ethically and be a responsible citizen.

Some vendors often manipulate their GSTIN to avoid tax payments. So, verifying the GST with a GST search number tool will let you understand if the vendor's invoice is genuine.

Moreover, GST verification helps you file correct tax returns for a given tax period. Plus, it lets you claim your Input Tax Credit, which you lose in case of incorrect or fake GSTIN.(Input Tax Credit lets you deduct the tax you have already paid on the purchase of goods while paying taxes during the supply of goods.)

GST Identification Number Format?

Even before conducting a GST search number check and assessing the validity of the GST number, you can determine whether it is in the correct format. The GST number structure consists of 15 characters. And here's what the 15 characters of a GSTIN stand for -

  • The first two numbers indicate the state code of the registered GST taxpayer.
  • The next 10 characters show the PAN number.
  • The next number is the entity number of the same PAN holder in a state.
  • The next character will always be the alphabet Z (by default).
  • The last character is usually a number, which is a check code for the detection of errors.

Where and How to Complain About Fake GSTIN?

You must check the GSTIN in a GST number search tool before clearing any invoice. If you see that the GST number is fake or invalid, you can always complain to the competent authority.

You can file your complaints at the GST complaint portal. It is an easy process where you don't need to write emails or make calls. Just follow these steps -

  • Enter the keyword related to your complaint in the 'Type the Issue or Concern' box.
  • You'll see a list of problems related to the given keyword. Select your specific problem.
  • The system will provide some FAQs related to the issue. Read them and see if they solve the issue.
  • If the FAQs don't solve your problem, you can file a complaint.
  • Click on 'No, I want to lodge my complaint.
  • You will get redirected to a page where you have to type the issue.

There you go! You have successfully lodged your complaint.
