How to Find the Correct Postal Code
- Use the recipient's complete street address, including the unit number when applicable.
- Check the postal code with Canada Post's official lookup service.
- Copy the six-character code exactly as shown, including the space in the middle.
- Do not rely on a city or community name alone when sending important mail.
Because postal codes are assigned to specific delivery points, two addresses in the same community may have different postal codes. An exact address lookup is the safest way to confirm the code.
