Editing House numbering (section)

== Southeast Asia ==
The most common street address formats in Vietnam are:

* A number followed by the street name, for example "{{lang|vi|123 đường Lê Lợi|italic=no}}". This is the most basic, most common format.
* A number with an alphabetic suffix: "{{lang|vi|123A đường Lê Lợi|italic=no}}", "{{lang|vi|123B đường Lê Lợi|italic=no}}", etc. This format occurs when a property is numbered 123 but later subdivided into two houses with different addresses.
* If the house lies on an [[Hẻm|hẻm/ngõ]] (alley), the alley number is combined with the house number: for example, in "{{lang|vi|123/3 đường Lê Lợi|italic=no}}", 123 is the alley's address, and 3 is the house number on that alley.
* More complex house numbers may occur on alleys that branch from other alleys or properties on alleys are subdivided, for example "{{lang|vi|123/3E đường Lê Lợi|italic=no}}" or "{{lang|vi|123/3/5B đường Lê Lợi|italic=no}}". An extreme example would be "{{lang|vi|7/14/12/3/23a đường 182|italic=no}}", which is located on 3rd alley off 12th alley off 14th alley off 7th alley off 182nd street.

Another scheme is based on residential areas called {{lang|vi|cư xá}}. A {{lang|vi|cư xá}} is addressed by house number, road, and {{lang|vi|cư xá}}, for example "{{lang|vi|123 đường số 4 cư xá Bình Thới|italic=no}}". Some localities still use an older address format based on neighborhood ({{lang|vi|khu phố}}): for example, in "{{lang|vi|7A/34 Tô Hiến Thành|italic=no}}", 7A is the neighborhood number. This confusing format is being gradually phased out in favor of the more modern formats above.
