GST Search by PAN in 2026: How to Find & Verify GST Registrations

A PAN is a useful starting point, but business due diligence should not stop at “I found a GST number”.

You should confirm:

• GSTIN;
• legal name;
• registration status;
• effective date;
• constitution;
• principal place of business information shown;
• cancellation details, if any;
• return-filing information available on the portal.

1. How PAN and GSTIN Are Connected

PAN is mandatory for normal GST registration, subject to statutory exceptions for specific categories.

During a new registration application, the GST portal can display GSTINs/provisional IDs/UINs mapped to the same PAN before the applicant proceeds.

This helps detect existing registrations and duplicates.

2. Public GST Verification: Search by GSTIN/UIN

The GST Portal user manual confirms that Search Taxpayer can be used without login.

Go to gst.gov.in Official ↗ and open:

Search Taxpayer → Search by GSTIN/UIN

Enter the GSTIN/UIN and captcha.

The portal can show public details such as:

• GSTIN/UIN;
• legal name;
• trade name;
• effective date of registration;
• constitution of business;
• principal place of business;
• cancellation date, if applicable;
• return-filing information.

After login, additional information may be available according to the portal.

3. How to Use PAN When You Do Not Know the GSTIN

Because GST registrations are PAN-linked, PAN can help identify or reconcile registrations through GST registration/account workflows and authorised portal features.

However, public search features can change, and the portal may expose different PAN-search functions depending on login/workflow.

For third-party due diligence, the cleanest process is:

1. obtain the supplier’s GSTIN from invoice/contract;
2. verify the GSTIN on the official portal;
3. match the legal name and PAN portion;
4. check active/cancelled status;
5. review filing details and invoice information.

4. Understand the GSTIN Structure

A GSTIN is a 15-character identifier.

The PAN is embedded in the GSTIN.

That helps you cross-check whether the GSTIN quoted by a vendor is structurally connected to the PAN/entity you expect.

Do not use the GSTIN structure alone as proof that the number is active—always query the official portal.

5. What an “Active” GSTIN Does and Does Not Prove

An active GSTIN confirms current registration status shown by the GST system.

It does not automatically prove:

• the vendor owns the bank account you received;
• the invoice is genuine;
• the supply actually occurred;
• ITC is automatically admissible;
• the vendor has filed every return correctly;
• the business has every sector licence required.

ITC eligibility depends on GST law and transaction evidence, not merely an active GSTIN.

6. Vendor Verification Checklist

• ○ GSTIN searched on gst.gov.in Official ↗
• ○ Legal name matches invoice/contract
• ○ Trade name reviewed
• ○ Status is active where required
• ○ State code and place of supply make sense
• ○ Principal place/business details reviewed
• ○ Cancellation date checked
• ○ Return-filing history reviewed where relevant
• ○ Bank-account beneficiary name independently verified
• ○ Invoice appears in applicable GST records/reconciliation process before ITC reliance

7. Common Mistakes

Treating PAN search as proof of GST compliance

PAN only connects identity. You still need GSTIN-level verification.

Assuming an inactive supplier automatically settles the ITC question

ITC consequences depend on timing, actual supply, invoice, tax payment/return conditions and current law. Avoid oversimplified claims.

Using third-party GST lookup sites as the final source

Third-party tools can be convenient, but the official GST portal should be the primary verification source.
