What is TIN?
A Taxpayer Identification Number (TIN) serves as a unique identifier for tax purposes. In India, prior to the Goods and Services Tax (GST) regime, TIN specifically referred to the Value Added Tax (VAT) identification number issued to businesses. This 11-digit number was crucial for tracking business transactions within and between states. The last two digits of this 11-digit TIN indicated the state where the business was registered, with the initial nine digits assigned by the respective state government. The possession of this number affirmed the legitimacy of a company for VAT purposes.
This system aimed to establish a centralized database for tax-related information concerning businesses operating across different states. It facilitated transparency and simplified the monitoring of transactions for tax authorities.

How to Apply for Tax Identification Number (TIN) Online (Historical Context)?
Before the implementation of the Goods and Services Tax (GST) in India, businesses applied for a Taxpayer Identification Number (TIN) primarily for Value Added Tax (VAT) purposes. While the VAT system has been subsumed by GST, understanding the former process for obtaining a TIN can provide historical context regarding business tax identification. The following steps outline how a VAT-related TIN was applied for online:
Step 1: Visit the official website of the VAT portal or Commercial Tax Department in your state. (The TIN was a part of the VAT, so you could find it on your VAT certificate.)

Step 2: Complete the registration process on the VAT portal by filling out the registration form with all the required information. (Remember, each state had its VAT website, so it’s important to check your respective state’s VAT website for accurate information.)
Step 3: Upload the necessary documents such as identification proof, address proof, business registration documents, and any other supporting documents as specified.
Step 4: Submit the registration form and supporting documents through the online portal.
Step 5: The Commercial Tax Department would carefully review and verify the submitted form and documents.
Step 6: Once your registration was approved, the tax authority would generate your Tax Identification Number (TIN) and provide you with a provisional certification for your business.
Step 7: A VAT inspector employed by the state government would visit your business address for final verification.
Alternatively, if you were looking for TIN facilitation centres, you could easily find them through the NSDL website. Here are the steps to follow:
Step 1: Visit the official TIN website and locate the ‘Facilitation Centre’ option in the menu.

Step 2: Click on ‘Search TIN FC’ and either enter your city’s PIN code or search for the facilitation centers based on the state or city.

Step 3: Once you entered the relevant information, a list of TIN facilitation center representatives and their key details would be displayed.

How to Know the TIN Application Status?
Online Status Check:
The NSDL portal primarily facilitated services for PAN and TAN. For historical VAT-related TIN applications, status checks were generally conducted through the respective state’s Commercial Tax Department or VAT portal, using the application reference number provided during submission. As the VAT system has been replaced by GST, this specific online status tracking method for VAT TIN is no longer applicable.

Phone and SMS Verification:
Similarly, phone and SMS verification services were typically associated with PAN and TAN applications handled by NSDL. For historical VAT TIN applications, applicants would have relied on the contact details and procedures provided by their state’s Commercial Tax Department for status inquiries. These methods are no longer applicable for VAT TINs post-GST.
How to Search for a TIN?
After the Commercial Tax Department of the state assigned a TIN (Taxpayer Identification Number), dealers and businesses could start selling goods. These businesses would include the TIN on their invoices and provide it to relevant parties involved in transactions.
To verify the authenticity of dealers or companies, individuals could check their TIN numbers on the official website of the Commercial Tax Department in the state where the dealer was registered. This online verification process allowed individuals to confirm the details of dealers or companies before doing business with them.
To verify a TIN, follow these steps:
Step 1: Visit the official website of the Commercial Tax Department in your state.
Step 2: Look for the ‘Dealer search’ option.
Step 3: Enter the TIN of the dealer.
Step 4: Click on the ‘Search’ button.
These results would provide important information about the company, including details such as the business name, license status, address, and PAN (Permanent Account Number) to aid in verifying the company’s authenticity before engaging in any business transaction.
What is the Format of a TIN?
The VAT-related TIN typically followed a format of 11 characters. The first nine characters were assigned by the state government, while the last two characters indicated the state of the applicant. This means that the state government provided the initial portion of the TIN, and the remaining characters helped identify the state associated with the TIN.

Note: GSTIN and TIN are both identification numbers used for taxation purposes. However, they operated within different taxation systems and had distinct procedures and rules for issuance.
Historically, like PAN, the VAT-related TIN played a vital role in establishing a business entity’s trustworthiness with customers and the government. Under the VAT regime, businesses were required to include their TIN on invoices. While the direct application for a VAT TIN is no longer applicable with the advent of GST, the principle of having a proper tax identification number (now GSTIN) remains crucial for transparency, compliance, and successful business operations.
