Canadian Postal Codes:
A Canadian postal code is a six-character string that forms part of a postal address in Canada.
Canada's postal codes are alphanumeric. They are in the format A9A 9A9, where A is a letter and 9 is a digit,
with a space separating the third and fourth characters.
There are some exceptions - The letters D, F, I, O, Q and U never appear in a postal code because of their visual similarity to 0, E, 1, 0, 0, and V respectively. In addition
to avoiding the six; letters W and Z also do not appear as the first letter of a postal code.
