The Standard Geographical Classification (SGC) is a system maintained by Statistics Canada for categorizing and enumerating the census geographic units of Canada. Each geographic area receives a unique numeric code ranging from 1 to 10 digits, which extend telescopically to refer to increasingly small areas. This geocode is roughly analogous to the ONS coding system in use in the United Kingdom.
The SGC code format for regions is X, where X is a unique identifier incrementing from east to west, then north.
The SGC code format for provinces and territories is XY, where X is the above regional prefix, and Y is a further identifier incrementing from east to west. Taken as a single digit, each value of Y is unique within the province group, or unique within the territory group.

11: Prince Edward Island
12: Nova Scotia
13: New Brunswick
59: British Columbia
61: Northwest Territories
The SGC code format for census divisions is XX YY, where XX is the above province/territory code, and YY is the census division's code, unique within its own province. Census divisions are generally numbered from east to west. In some locations, a similar policy to American FIPS county codes has been adopted, with even-numbered slots being left vacant for future expansion.

The SGC code format for census subdivisions is XX YY ZZZ, where XX is the province/territory code, YY is the census division code, and ZZZ is the census subdivision's code, unique within its own census division. Census subdivisions are again generally numbered from east to west, and the practice has been to leave even-numbered slots vacant for future expansion.
