SIN Validation (Canada)

What does the validator check?

Checks if the SIN passes the Luhn algorithm (modulo 10), the same used for credit cards. The sum of processed digits must be divisible by 10.

When is it considered invalid?

When it doesn't have exactly 9 digits or the Luhn sum isn't divisible by 10.

Use in development

Canadian HR and payroll systems need to validate SIN. The validator helps test Luhn algorithm implementations.
