You can search or verify a GST number for free using the Search Taxpayer tool on the official GST portal, without logging in. Enter a GSTIN/UIN to check a business or use Search by PAN to find GST registrations linked to a PAN. The results typically show the legal name, registration status, registration date, and taxpayer type.
A quick GSTIN check can help you avoid invoice and input tax credit issues. Before dealing with a new supplier, confirm that the GSTIN is valid and shows an Active status. The official portal supports searches by GSTIN/UIN and PAN, but not by business name.

Methods to Search GST Number Online
Below are some common methods for GST number search:
- GST Portal Search: The official GST portal at gst.gov.in lets you search taxpayers using a GSTIN/UIN or PAN, without logging in. A logged-in account may provide additional taxpayer details. However, the portal does not support searches by business name.
- Third-Party GST Search Tools: Several online platforms provide tools to help you find a GST number quickly by entering basic business details. These tools use data from the GST database to deliver accurate results.
- Mobile Apps: Several GST apps, including the official GSTN e-Services app, provide a convenient way to search and verify GST details. These apps are available on both Android and iOS platforms.
How to Check GST Number by PAN? Step-by-Step Guide
Finding a GST number by using the business’s PAN is a straightforward process. Here’s how to do it:
- Visit the GST portal: Open the official GST website at gst.gov.in.
- Open Search Taxpayer: Go to Services → Search Taxpayer → Search by PAN.
- Enter the PAN: Enter the taxpayer’s PAN and the displayed captcha, then submit the search.
- View the results: The portal displays GSTINs linked to the PAN across states, along with their status of GST registration. Select a GSTIN to view available details such as the legal name, registration date, and taxpayer type.
- Check the status: Look for an Active status before relying on the GSTIN for a transaction or related tax compliance.
Note: The official GST portal does not support searches by business name. If you only know the business name, use a reliable third-party search tool.
Common Errors and Troubleshooting in GSTIN Search
While searching for a GST number, users may encounter a few common issues. Here are some common errors and troubleshooting tips:
- Incorrect GSTIN or PAN: Ensure the details entered are correct, as even a small mistake can lead to inaccurate search results.
- Search Not Returning Results: If the search doesn’t return any data, check the details entered. Also, ensure the business is registered under GST, as some businesses may not have a GST number.
- GSTIN Status Shows “Inactive”: If the GST check shows the status as inactive, it could mean that the business has either canceled its registration or is not compliant with GST regulations.
- Technical Errors: Sometimes, the portal may face technical glitches. If the website isn’t loading or the search isn’t working, try refreshing the page or using the service at a later time.
