Canada and zip codes are completely different from the zip codes of the United States, although they are adjacent countries.
Canada does not have a household registration system, and the main contact with the government is by letter. No matter where you move, you must have a contact address and zip code. As for postal codes, postal codes in Canada are 6 digits, consisting of numbers and letters. The U.S. zip code is made up of 5 digits.
Postal codes in Canada are similar to those in the United Kingdom and Finland, in the form of A1A 1A1. A group of three characters, and a space symbol is reserved between the two groups. There are said to be 850,000 groups of postal codes in Canada, and the postal codes are arranged from east to west, because the east is the first province in Canada to see the sun.
There are also some tidbits about postal codes in Canada. That is, although the zip code uses a combination of more than 850,000, it can locate all parts of the country. However, the letters D, F, I, O, Q, U are not used in postal codes, it is said that these letters are easily combined with O. E, 1, 0, and V are confused because they were all handwritten before. If the handwriting is unclear, it is easy to make mistakes in sorting.
Secondly, the first letters will not be W and Z, because there are not so many regions in the country, and Z is easily confused with 2. The birth of zip code is to identify the machine, the machine will take a picture of the zip code, then identify it, enter the postal system, and start distribution and tracking.
The postal codes of Canada's national regions are designated by the Canada Post Company. If a new community is built, the postal codes and addresses of this area will be designated by the company, and users cannot choose. Since Canada's zip code can be precisely located to the community, leaking the zip code can easily reveal personal privacy.
