This is a list of postal codes in Canada where the first letter is B. Postal codes beginning with B are located within the Canadian province of Nova Scotia. Only the first three characters are listed, corresponding to the Forward Sortation Area (FSA).
Canada Post provides a free postal code look-up tool on its website,[1] via its mobile apps for such smartphones as the iPhone and BlackBerry,[2] and sells hard-copy directories and CD-ROMs. Many vendors also sell validation tools, which allow customers to properly match addresses and postal codes. Hard-copy directories can also be consulted in all post offices, and some libraries.
There are currently 77 FSAs in this list. B7* and B8* codes are currently not in use.
