While it stays as the currency of Vietnam, 2014 is the year South Korea gets rid of the word "dong" in its addresses. (FYI, the currency in Vietnam is called dong.) So say goodbye to Itaewon-dong, Mok-dong, Banpo-dong, Shillim-dong, Sadang-dong, Gaepo-dong, and a countless number of other dongs. While those sexy names will remain in use by many people, road names will be officially used from now on. That would mean all mail addresses have changed even though the old ones will still work for quite some time. Most GPS navigation systems will also support both address types even though some may require updates.
Building Number Plates
Most building number plates are in blue color and house-shaped. The upper half shows the name of the road in Korean and English. (Some signs are also in Chinese or Japanese.) The lower half shows the building number.
Building Numbers: Easy as 1, 2, 3
The new address system relies more on numbers and less on letters, which can be easier to understand. For example, a building number that ends with 1, 3, 5, 7, or 9 indicates the building is on the left or northern side of the road. A building number that ends in 0, 2, 4, 6, or 8 would be on the right or southern side.
Also, by subtracting two numbers, one can calculate the distance between two locations. For instance, if a person is going to Gangnam-daero 300 from Gangnam-daero 200, the distance would be approximately 1 km or 0.62 miles. (Subtract the smaller number from the bigger number and divide it by 100.)
