OPCC: Open Postal Code Correspondence
An open, fully reproducible alternative to closed postal code
conversion files, giving source-qualified many-to-many correspondence
between Ontario postal codes and Statistics Canada 2021 census
geographies. Every published artifact can be rebuilt step by step from
public sources using the included build functions, so any user can
reproduce and audit the conversion end to end. Lookup results retain
allocation weights, evidence source, lineage, method, and vintage;
unmatched postal codes remain explicit, and versioned release artifacts
are checksum-verified before use. A built-in 'shiny' application provides
a point-and-click interface for joining, mapping, and exporting results.
Correspondences are derived from the Statistics Canada National Address
Register <https://www150.statcan.gc.ca/n1/pub/46-26-0002/462600022022001-eng.htm>,
the 2021 Census Geographic Attribute File
<https://www12.statcan.gc.ca/census-recensement/2021/geo/aip-pia/attribute-attribs/index-eng.cfm>,
and the GeoNames postal code export
<https://download.geonames.org/export/zip/>. The package does not
redistribute Canada Post, PCCF, or PCCF+ data and does not claim
authoritative postal assignments.
