International Dialing Laos
This is the international dialing code used when dialing from Laos. International Dialing Laos Code is also known as Laos International Direct Dialing prefix (or IDD) is used when dialing from the Laos to outside Laos (sometimes also refers to as Laos international access code). Do not use Laos IDD code when dialing within Laos. By simply using the Laos Dialing Code before the number, it unables you to place a call to outside Laos from within Laos. Without this international dialing Laos Code, you will not able to place a call outside the Laos because the telephone exachange will not reconginize it as a valid international call.
To dial a international number outside Laos from within Laos, you have to dial International Dialing Laos Code or Laos International Direct Dialing prefix (IDD), Laos Country Code, City/ Area Code, and then the subscriber telephone number respectively as:
+856 (International Dialing Laos Code) + (Country Code) + City Area Code + Number you wish to call.
When dialing from a mobile phone outside Laos from Laos, only Dial '+' + (Country Code) + City Area Code + Number you wish to call. (The "+" is universal mobile international direct dialing prefix also includes Laos)
On the other hand, when dialing to Laos from outside Laos, a Laos Country Code is used. Laos Country Code however is not used when dialing within Laos.
The other type of code is Laos National Direct Dialing prefix (or NDD). It is used only when dialing to a destination within the Laos (Refer to dialing Laos code). Laos NDD code is only used as long distance dialing within the Laos. Do not use Laos National Direct Dialing prefix when dialing from outside Laos into Laos.
