Introduction

In the B2B ecosystem, having accurate contact details such as mobile numbers linked to a business’s GSTIN can greatly enhance communication, lead generation, and compliance verification. However, finding the mobile number associated with a GST number is not straightforward due to strict data privacy regulations.

This blog explores the legitimate ways to access or verify mobile numbers linked to GSTINs, the challenges involved, and best practices for businesses and professionals.


1. What is GSTIN and Its Link to Mobile Numbers?

The Goods and Services Tax Identification Number (GSTIN) is a unique identifier assigned to every registered taxpayer in India. When registering for GST, businesses provide essential details including a mobile number used for OTP verification, communication, and compliance updates.

While the mobile number is a critical piece of data for official communication, it is classified as personal and sensitive information and hence is not publicly accessible through government portals.

ReasonExplanation
