What is the difference between a civic and mailing address?

A civic address is the official number and street name that is assigned to a property, building or structure for identification and emergency dispatch procedures. It is a unique identifier for location purposes and does not include a postal code. 

A mailing address is used by Canada Post to sort and deliver communications to your location. In the City of Dawson it identifies your location by a post office box and it includes a postal code.
