The Canadian Postal Code consists of 6 characters, where the first three characters are the 'Forward Sortation Area (FSA)', with the last three characters being the 'Local Delivery Unit (LDU)'. In the case of Unionville, we provide only the FSA and not the LDU. The Canadian Postal Codes were created as a way of grouping addresses to make delivery more efficient. So keep in mind that any given Postal Code is only 'loosely' associated with a community (such as Unionville). The boundaries of the Postal Code can be changed, re-assigned, eliminated or overlapped with other Postal Codes. When looking for a Postal Code, whether Unionville or elsewhere, it's always best to check the website of the Canada Post / Postes Canada.
