A Canadian postal code has six characters in the form A1A 1A1. The first three characters are the Forward Sortation Area (FSA), and the last three are the Local Delivery Unit (LDU), which narrows to a specific block or building.
Neighbourly keys postal data with FSAs and LDUs, joining them to addresses so a postal code can be resolved to its area demographics and location hierarchy.
