The large red numbers can be used to quickly find the detailed map of an area with the red thumb index along the edge of the map pages. Every Rural FSA Area Map in the Atlas is followed by individual maps of cities with two or more FSAs in it, indicated by a large red dot. If a second urban FSA has been added to a single one recently, a map might not be available. Single Urban FSA towns near a large urban area appear often in both the rural maps and, in detail, in the appropriate urban maps. The maps are in various scales, and for that reason can not be compared directly for distance measurement.
Map orientation is north-vertical unless otherwise indicated by an arrow.
Some rural communities that have not been assigned a unique six-digit postal code could often be found on standard road maps, but not in this Atlas. Conversely, some localities featured in the Atlas are very small, and can only be found in Government databases. The city or town providing service to a rural FSA is shown on the Rural Area Maps in small capitals below or above the FSA label. Names of places and urban areas in the Atlas reflect the Canada Post usage and structuring of the Postal Coding system. In some cases they differ from other official publications.
