# PAN to GSTIN

> Use Cashfree PAN-to-GSTIN verification to fetch every GSTIN linked to a business PAN, streamlining vendor onboarding, KYB checks, and tax compliance.

PAN to GSTIN verification allows you to fetch all Goods and Services Tax Identification Numbers (GSTINs) associated with a specific Permanent Account Number (PAN). This service is essential for comprehensive business verification and tax compliance processes.

## What is PAN to GSTIN mapping?

* **Verify business scope**: Understand the geographical and operational scope of a business
* **Ensure compliance**: Verify all tax registrations for comprehensive KYB processes
* **Prevent fraud**: Cross-verify business claims against actual registrations

## Key features

* **Comprehensive mapping**: Retrieve all GSTINs associated with a PAN
* **Real-time data**: Access up-to-date information from authoritative sources
* **Bulk verification**: Verify multiple business registrations in one call
* **Integration ready**: Easy API integration for seamless workflows

## Response data

The API provides comprehensive information for each GSTIN associated with the PAN:

* **GSTIN number**: The 15-digit GST identification number
* **Legal name**: Registered business name
* **Trade name**: Business trade name (if different)
* **Registration date**: GST registration date
* **Status**: Current status (Active, Cancelled, Suspended)
* **Business type**: Type of business entity
* **Address**: Registered business address
* **State code**: State where the GSTIN is registered

## Best practices

* **Verify all GSTINs**: Don't rely on just one GSTIN for business verification
* **Check status**: Ensure all GSTINs are active and valid
* **Regular updates**: Re-verify periodically as business registrations can change
* **Cross-reference**: Use this data alongside other KYB verification methods
