Forward Sortation Area—Definition

A forward sortation area (FSA) is a way to designate a geographical unit based on the first three characters in a Canadian postal code. All postal codes that start with the same three characters—for example, K1A—are together considered an FSA.

The Forward Sortation Area consists of the three first chacarters of a postal code

Each character in an FSA code provides information:

  • The first character is a letter that identifies the province or territory (although Nunavut and the Northwest Territories share the letter X). For Ontario and Quebec, this first character further identifies a particular part of the province: for example, G identifies Eastern Quebec, H Metropolitan Montréal, K Eastern Ontario and M Metropolitan Toronto (see map).
  • The second character is a numeral that identifies whether the area is urban or rural. A zero indicates a wide-area rural region, while all other digits indicate urban areas.
  • The third character is a letter that, in combination with the first two characters, identifies a more precise geographic district—a specific rural region, an entire medium-sized city or a section of a major metropolitan area.
