1. Introduction
In Canada, Tax Identification Numbers (TINs) are essential for individuals, businesses, and other entities to comply with federal tax regulations. These identifiers facilitate accurate tax reporting, benefit claims, and financial transactions. The information provided here is verified from official sources, including the Canada Revenue Agency (CRA) and other government publications.

Canada utilizes several types of TINs, each serving specific purposes:
- Social Insurance Number (SIN): A unique 9-digit number issued by Service Canada to individuals for income tax and benefit purposes. Government of Canada
- Business Number (BN): A 9-digit identifier the CRA assigns to businesses and organizations for tax-related activities. Government of Canada
- Individual Tax Number (ITN): Issued by the CRA to non-resident individuals who are not eligible for a SIN but require a TIN for Canadian tax purposes. Government of Canada
- Trust Account Number: Assigned by the CRA to trusts for tax filing and reporting.
3. TIN Format and Structure
- SIN: 9 digits (e.g., 123-456-789).
- BN: 9 digits (e.g., 123456789).
- ITN: 9 digits, beginning with “9” (e.g., 900123456).
