Vietnam - Personal names and forms of address


There is no single set of personal address forms used in Vietnam. Names are written with the family name first followed by the given name. Men often insert a word such as công, ðú’c, hũ’u, quang or văn and women a word such as thi between their family and given names in this way:

   Dag thi Thu

This middle name indicates a generation, separates branches within a big family and/or indicates a person’s birth order within a large family. Given names often have a literal meaning, such as birth or flower names, or attributes such as intelligence or modesty, or their birth order.

A large number of Vietnamese share a relatively small number of family names. Women do not always take their husbands’ name upon marriage, though they may use it in informal situations.

A younger person will use the form of address Ong for older males and Ba for older females. An older person will use the form of address Anh (which may also be a given name) for a younger man and Chi or Co for a younger woman. Em is the form of address used for close friends or relatives; and Bac ("uncle") is used to show respect to non-relatives.

Vietnam - Postal codes


   Note: This section last updated 27th May 2020

Vietnam changed its postal code system from 5- to 6-digits in 2004 and then reverted back to a 5-digit system in 2018.The first digit is a regional code, the next one identifies a province or municipality, the next two a district and the final one a commune, post office or foreign embassies, consulates or missions, which may have their own codes.

Codes currently do not commence with any of these numbers or number ranges: 09, 19, 27-29, 37-39, 58, 68-69, 79, 88-89, 93, 99.

Vietnam Post have also introduced a positional addressing system called Vpostcode, which is a 13-character code commencing with the postal code followed by a space and then 7 alpha-numeric characters, in this way:

   12014 2QJJ52H 

As they are positional codes pointing to a specific latitude and longitude, interpretable only through a mobile telephone app, rather than postal codes in the traditional sense, I do not categorise them as postal codes in this resource.
