Laos +856

Laos, officially the Lao People's Democratic Republic, is a landlocked Southeast Asian nation known for its mountainous terrain, French colonial architecture, and Buddhist monasteries. For international telecommunications, Laos is assigned the country code +856 by the International Telecommunication Union (ITU). This code is essential for any inbound or outbound international call involving Lao numbers. The country's telephone network is administered by the Ministry of Technology and Communications, with services provided by state-owned Lao Telecom and other private operators like Unitel and Star Telecom (Beeline). Understanding the structure of Lao phone numbers is crucial for businesses, expatriates, and travelers who need to maintain reliable communication within the country and across borders.

How to Call Laos from Abroad

Placing an international call to Laos requires a specific sequence of digits that includes the international exit code, the Laos country code, the area or destination code, and the local subscriber number. The standard format is: International Exit Code + 856 + Area/Destination Code + Local Number. The exit code varies by the country you are calling from—for example, it is 011 in the United States, 00 in most European and many Asian countries, and 0011 in Australia. After dialing the exit code, you must enter 856, followed by the appropriate Lao area code (without the leading '0' that is used for domestic calls). Finally, dial the local number, which typically consists of 7 to 8 digits for landlines and 8 digits for mobile phones.

For instance, to call a landline in Vientiane, the capital, from the US, you would dial: 011 856 21 123456 (where 21 is the area code for Vientiane and 123456 is the local number). To call a mobile phone in Laos, you would dial: 011 856 20 12345678, where '20' is the mobile prefix. Note that '20' is not an area code but a mobile network indicator, and it is essential to include it when dialing a Lao mobile from abroad. Omitting the '0' from the domestic trunk prefix is a common mistake; always remember to drop the leading '0' when dialing internationally.

Area Codes and Numbering System

Laos uses a hierarchical numbering plan with area codes assigned to provinces and specific cities. The capital, Vientiane, uses the area code 21. Other major area codes include: Luang Prabang (71), Savannakhet (41), Pakse (31), and Champasak (31). However, the mobile network dominates telephony in Laos, with numbers beginning with 20 (all mobile operators), 30 (for some VoIP services), and 54 (for certain satellite services). Since the government introduced a unified numbering plan, all mobile numbers are now 8 digits long, starting with '20' followed by 6 digits. For example, a typical mobile number looks like 020 12345678 domestically, and internationally as +856 20 12345678.

It is important to note that area codes are not always strictly geographic, especially with the rise of mobile phones. Many residents and businesses in Laos rely solely on mobile phones, and even landline numbers may be assigned to different regions without clear geographic boundaries. When calling from abroad, you must always include the area code (or mobile prefix) even if the number you are trying to reach is in the same city. The Lao numbering plan does not have a separate 'trunk prefix' like some countries; the '0' is used only for domestic dialing and is always omitted when calling from overseas.

Special Rules and Considerations

When making international calls to Laos, there are several special rules to keep in mind. First, the use of the plus sign (+) is the most reliable way to dial from mobile phones, as it automatically selects the correct international exit code for your current location. For example, you can dial +856 21 123456 directly from your smartphone. Second, if you are calling from a country that uses a different exit code, always verify the correct digits—dialing the wrong exit code will result in a failed call. Third, be aware that some Lao numbers, particularly older landlines, may have fewer or more digits than the standard 7-8 digits. The current national numbering plan specifies that landline numbers are 7 digits (including the area code) and mobile numbers are 8 digits (including the mobile prefix '20'). However, some rural areas may still have 5- or 6-digit numbers, which are being phased out.

Another critical consideration is the use of VoIP and internet-based calling services. While international calls to Laos are generally reliable, the quality may vary depending on the operator and the region. In remote areas, connectivity can be poor, and it is advisable to use a satellite phone or a local SIM card with a strong network for critical communications. Additionally, Laos has implemented a strict SIM card registration policy, requiring foreigners to present their passport when purchasing a local SIM. This is important for travelers who plan to use a Lao number for local calls, as they must register the SIM in their name.

Traveler and Business Tips

For travelers and business professionals, understanding the local dialing norms is essential. When you are inside Laos, domestic calls are made by dialing the full number including the leading '0' (e.g., 021 123456 for a Vientiane landline, or 020 12345678 for a mobile). To call another country from Laos, you must first dial the international exit code 00 (or use the '+' sign on a mobile phone), followed by the destination country code, area code, and local number. For example, to call the United States from a Lao landline, you would dial 00 1 212 1234567.

For businesses, it is recommended to maintain accurate records of Lao numbers in international format (+856) to avoid confusion. Many Lao companies use mobile numbers as their primary contact, so ensure that you have the correct mobile prefix (20) when dialing. Also, be aware of time differences; Laos is in the Indochina Time Zone (ICT, UTC+7) and does not observe daylight saving time. This means that during winter months, the time difference with many Western countries may be larger, affecting business hours. Finally, consider using messaging apps like WhatsApp or Viber, which are widely used in Laos, to reduce costs and improve connectivity, especially when calling abroad.

In recent years, Laos has expanded its telecommunications infrastructure, with 4G and 5G services becoming available in urban centers. However, in rural and mountainous areas, signal coverage remains sporadic. For international travelers, purchasing a local SIM card from operators like Unitel or Lao Telecom is often the most cost-effective option, as they offer competitive data and call packages. When making international calls to Laos from abroad, be mindful of the rates charged by your home provider—some may consider Laos a 'high-rate' destination, so using a VoIP service or a calling card might be more economical. Overall, with proper knowledge of the dialing format and special rules, staying connected with Laos is straightforward and efficient.
