The company you are adding is a Canadian company. Canada is not comprised of states, but rather of provinces—10 to be specific. How are you going to accommodate the province of "Ontario," in this specific example? Also, Canadian zip codes are alphanumeric. They are in the format A1A 1A1, where A is a letter and 1 is a digit, with a space separating the third and fourth characters. Can your database design handle this zip code format?
