To dial home from Laos, use the international access code 00, followed by the destination country code, area code and number you wish to dial. Local numbers should be prefixed with 0.

For calls to Laos, the international dial code prefix may vary depending upon the country from which the call is made, but will be followed by the Laotian international number +856, followed by the area code and local number.

The main police emergency number is 1191, which is free to call, and is suitable for use in all types of emergency.  However, police response is patchy in Laos, and there have been instances of unanswered calls. Additional free to call numbers are 1195 for fire emergencies and 1190 for an ambulance.

When travelling with Haivenu, you will also always be provided with an emergency contact number to access our help and assistance.

For mobile handsets, consult your service provider in advance of departure to activate your handset for use in Laos and seek advice concerning roaming charges, which are, however, likely to be expensive.

If your phone is unlocked, another option is to buy a SIM card locally, from one of the several networks, ETL and Unitel being the most widely used. It should be noted, however, that coverage beyond the cities and towns is sporadic.

You can also purchase contract free handsets locally, though you will also need to purchase a SIM card.


Many hotels in Laotian towns and cities provide free wifi access, along with several and restaurants in tourist areas, as well as internet cafes and bars who charge for access. It is not recommended to use such facilities for financial transactions to avoid the possibility of criminals accessing your most sensitive data.

Land based internet speeds are generally quite slow and the 3G mobile network is a more effective system in most cases.


The electricity supply in Laos is 230 Volts, at 50 HZ.

A useful visual reference guide to the full range of international plug and socket varieties can be found at, which describes the type system in use on this website.

As yet, there is no standardised socket system for Cambodia, and you will likely encounter different socket systems in hotels all over the country. The majority of connections are variants of two-pin outlets, some of which are round-pin (type C and type F), others flat pin blade types (type A).

There are also some 3 pin sockets in use, the flat blade type B and the round pin type E.

For this reason it is best either to carry a range of suitable adapters or invest in one of the new universal adapters with retractable pins which are adaptable to differing formats, particularly if you are travelling to more than one country. Usefully, some models also provide additional USB connections.

It is helpful to consider your likely needs in advance. If you will need to charge several items such as mobile phones, tablet computers, cameras etc., it may be worth bringing a multiple, preferably surge protected, outlet from your own country to avoid having to purchase several adapters, or to deal with a limited number of wall sockets.

In most cases, if your equipment normally runs on a 110 volt, 60 HZ supply, you will additionally need a portable transformer.


Although Laos has a traditional system of weights and measures, the model in everyday use is the international metric system based on the metre and gram.


Laotian postal services are run by Laopost (Enterprise des Postes Lao). Opening hours are from 08:00-12:00 and 13:00-17:00 on weekdays, and 08:00-12:00 on Saturdays. For ordinary post the service is generally reliable, but for high value items, a private carrier such as DHL or Fedex in Vientiane, although expensive, is the best option.


The time zone in Laos is GMT+7, though it should be noted for calculation purposes that the country does not operate a daylight saving mechanism.
