Canadian Business Number
The Business Number (BN) is a unique identifier assigned by the Canada Revenue Agency (CRA) to businesses and other entities for tax purposes. It is a 9-digit number used for various tax accounts, including GST/HST, payroll, and corporate income tax.
Although this identifier can be verified against official registries, not all entities are included in the linked sources. As a result, some valid identifiers may not be found during registry checks. We'll flag these as valid but not verified.
This identifier follows a strict format, here represented as X = alphanumeric character, A = letter, 0 = digit, and # = alphanumeric or special character (*, +, ?).
