A Canaian postal code is a string of six characters that forms part of a postal address in Canada. Like British and Dutch postcodes, Canada's postal codes are alphanumeric. They are in the format A0A 0A0, where A is a letter and 0 is a digit, with a space separating the third and fourth characters. An example is K1A 0B1, which is for Canada Post's Ottawa headquarters. According to Statistics Canada, about 850,000 postal codes exist in Canada, ranging from A0A in Newfoundland all the way to Y1A in the Yukon.
