Japanese addressing system
I think lots of places don&#x27;t have the numbering system that Americans take for granted.<p>In Vietnam my address is something like 422&#x2F;35&#x2F;11 Dien Bien Phu, Ward 17, Binh Thanh district, Ho Chi Minh City.<p>The number means &quot;go to the building #422 on the main road and turn down the unnamed road you see there; drive until you see the house numbered 35 and turn down the unnamed road THERE; then proceed to number 11.&quot;<p>Make sure you&#x27;re looking for #422 in Ward 17 and not some other stretch of the same road that might reuse those numbers.<p>Oh, and if you&#x27;re still using the old address system then I&#x27;m actually at 107&#x2F;11b. (&quot;B&quot; because a single lot was subdivided once upon a time.)<p>Notice there are no zip codes.<p>99% of web forms outside of Vietnam can&#x27;t handle my actual address. They require a zip code or disallow the &quot;&#x2F;&quot; character or don&#x27;t have room anywhere to write the Ward and District. Last time I checked, Open Street Maps didn&#x27;t know how to parse my address and find my house.<p>And this is for a country with 100 million people -- more than France, the Netherlands, and Belgium combined. I&#x27;m sure other developing countries, also with tens of millions of people, have their own idiosyncrasies that get papered over by Western developers.
