Supported Operations

The following operations are supported for Vietnam:

  • Geocoding—Takes one or more addresses as input and returns latitude/longitude coordinates and other information.
  • Reverse Geocoding—Takes one or more latitude and longitude coordinates as input and returns the address of the location.

Input Fields

The input address may contain some or all of the following address elements.

Field NameParameter Type Description
placeName String Specifies the building name, place name, Point of Interest (POI), company or firm name associated with the input address. Optional.
mainAddress String Single Line Input—If no other address field is populated, then the mainAddress entry will be treated as a single line input. Single line input can consist of multiple input address fields; these should be entered in the typical address order for the country. For more details, refer to the section "Single Line Input" below.

Street Address—If the post address components (city, postalCode, etc.) are provided separately or in the lastLine field, then the contents of mainAddress will be treated as the street address part and can include company name, house number, building names and street names. Optional.

Street Intersection Input—To enter an intersection, specify the two street names separated by a double ampersand (&&).
lastLine String The last line of the address. Optional. For example:

Paseo Meneses

areaName1 String Specifies the state. Optional.
areaName2 String Specifies the region. Optional.
areaName3 String Specifies the city or town.

country String The three-letter ISO 3166-1 Alpha-3 country code. For Vietnam, the country code is VNM. Required for forward geocoding.

Single Line Input

Instead of entering each address component in separate fields, you can enter the entire address in the mainAddress input field with the address elements ordered as follows:

[street_info][address_number][areaName3][postal_code][areaName1]

Where:
  • [street_info] consists of the street name, street type and any pre- or post-directional information (e.g. East, West, etc.). Optional.
  • [address_number] is optional.
  • [areaName3] is the city.
  • [postal_code] is the postal code.
  • [areaName1] is the state.
  • Either the [areaName3] or [postal_code] is required.
For best results, put a comma between the street information and the last address line information.
