How SIN Number Validation Works

SIN Number Format

Canadian SIN numbers are 9-digit identifiers formatted as XXX XXX XXX:

Must be exactly 9 digits
First digit cannot be 0 or 8
Uses Luhn algorithm for validation
Often displayed with spaces: 123 456 789

Luhn Algorithm Validation

Our validator uses the Luhn algorithm to check SIN number validity:

Double every second digit from right to left
If doubled digit > 9, add its digits together
Sum all digits
Valid if sum is divisible by 10

Legitimate Use Cases for Testing SIN Numbers

Software Development

Test form validation, database schemas, and application logic without using real SIN numbers

Quality Assurance

Test edge cases, validation rules, and error handling in Canadian applications
