The DMTI Postal Code data includes six-digit postal codes for all of Canada. There are two types of postal codes provided, Unique Enhanced Postal Codes (UEP), and Multiple Enhanced Postal Codes (MEP). UEP is used more frequently because it provides a 1:1 relationship between postal codes and Statistics Canada's standard census geography. MEP takes into account that in some newer subdivisions, many streets will share the same postal code.  We also have boundary files for Forward Sortation Areas (FSA) - three digit postal codes and Local Delivery Units (LDU) - six digit postal codes for all of Canada. The data is current to 2020.
