Part of the problem is the different ways addresses are expressed throughout the world. I was born and grew up in Canada, and was confused when I started dealing with companies in China. Instead of street addresses, many are given by province, city, district, sub-district, and a building number. Another problem is choosing which authority for the "correct" address. I've seen many cases where the official postal address city/town name is different than the 911 database. For example Canada Post will say some street addresses are in Dartmouth, while the official civic address is really Cole Harbour. https://www.canadapost-postescanada.ca/ac/ https://www.canadapost-postescanada.ca/ac/ https://nsgi.novascotia.ca/civic-address-finder/ https://nsgi.novascotia.ca/civic-address-finder/ Even streets can have multiple official names/aliases. People who live on "East Bay Hwy", also live on "Highway 4", which is an alias.
