What is a Forward Sortation Area (FSA)? ▾
In the Canadian postal code system, the Forward Sortation Area (FSA) represents the first three characters of the code (e.g., M5V). The first letter represents the province or postal district, the number indicates whether it is urban (1-9) or rural (0), and the second letter represents a specific geographic area.
What is a Local Delivery Unit (LDU)? ▾
The Local Delivery Unit (LDU) represents the final three characters of a Canadian postal code. It specifies the exact block, building, or rural community for final mail delivery.
Why can't I find my exact 6-character postal code in open directories? ▾
While the first three characters (FSAs) are public data, the final three characters (LDUs) are copyrighted by Canada Post. Most open directories provide the FSA and require you to use an exact address lookup tool to pinpoint the full 6-character code.
