Personal Access Code (PAC) for My Service Canada Account
Service Canada may mail a PAC so you can register for My Service Canada Account online when you cannot use a bank partner sign-in. The PAC expires; treat it like a password and destroy the letter after use.
When you need a PAC
New benefit recipients or first-time registrants sometimes receive a PAC with a welcome package. If you lose it, you request a replacement through official channels rather than sharing numbers by email.
