Who this applies to: If your SIN starts with 9: We need to confirm it's valid and matches your name on file, since temporary SINs require manual verification. If you have a permanent SIN: Our system runs an automated check against historical SIN records to help verify your identity. Occasionally, that check cannot confirm a valid history for your SIN, so we may need one of the SIN documents below to verify your identity. |
