Verifying a GST number is crucial to ensure that the businesses you deal with are legitimate and GST-compliant. This step-by-step guide explains how to check GST numbers online in India easily and accurately.
What is a GST Number?
A GSTIN (Goods and Services Tax Identification Number) is a 15-digit unique identifier assigned to every GST-registered taxpayer in India. It is essential for:
- Issuing and receiving invoices
- Claiming input tax credit
- Ensuring compliance with tax regulations
- Tracking tax payments and returns
Each GSTIN is unique and structured in a standardized way to indicate the state, PAN, entity, and checksum for verification purposes.
