How do addresses in Vietnam work?

If you are sending something to Vietnam, you can leave the address in English or ask the recipients for the Vietnamese version. In general, the number of the house comes first and followed by lane number of street names, districts and cities.

Here are some useful words:
Quận/ Huyện: District 
Phố: Street 
Đường: Road 
Ngõ: lane 
Ngách: smaller than lane unit 
Số: House number 
Khu đô thị: Apartment building complex

Example of an address:

Chu Ngoc H. 
So 4, ngo 12, pho H.H, Dong Da, Hanoi.   

Note: Vietnam does not have postal code.
