Global TIN Lookup: Business Tax IDs by Country (2025)

Introduction 

A Business Tax Identification Number (TIN) is a government-issued unique identifier for businesses to track and manage tax obligations. It is mandatory for all entities engaged in taxable activities, ensuring accurate reporting and compliance. 

TINs are essential for domestic tax filings and increasingly important in cross-border trade, where verification of business identities is critical. Different countries use varying names and formats for these identifiers, such as VAT ID, GSTIN, or EIN, and maintain systems for validation. Proper understanding and use of TINs is fundamental for compliance and risk management in both local and international operations. 

The following is a comprehensive list of countries along with the specific names and formats of their Business Tax Identification Numbers, reflecting the diversity in tax identification systems worldwide.
