The Laos country code is +856 — reaching the only landlocked nation in Southeast Asia, ~7.5 million Lao across the Mekong heartland with mobile coverage from Lao Telecom (LTC), Unitel + ETL. From Vientiane business to Luang Prabang tourism, Lao bank OTPs (BCEL, Lao Development Bank) all expect +856.
Laos was assigned +856 by the ITU — placing it in zone 8 with mainland Southeast Asia. Vientiane (021) sits on the banks of the Mekong, directly across from Thailand.
Laos uses the +856 country code, placing it in ITU zone 8 alongside Thailand +66, Vietnam +84, Cambodia +855, Malaysia +60 + Myanmar +95. The "856" suffix is unique to Laos — the only landlocked country in Southeast Asia, ringed by Thailand, Vietnam, Cambodia, China + Myanmar.
Laos's telecom industry is regulated by the Ministry of Technology and Communications (MTC). Three main carriers: Lao Telecom (LTC, the partly state-owned incumbent), Unitel (Star Telecom — a Viettel joint venture, the largest by subscribers) + ETL (Enterprise of Telecommunications Lao). All Lao mobiles use the 20 prefix.
Lao area codes carry a leading 0 domestically (dropped internationally). Major: <b>021</b> Vientiane (the capital), <b>071</b> Luang Prabang (UNESCO town), <b>041</b> Savannakhet, <b>031</b> Pakse (Champasak). Lao mobiles all start with <b>20</b> — written +856 20 XXXX XXXX internationally (020 XXXX XXXX domestically).
Laos is the "battery of Southeast Asia". The Mekong River — the country's spine — powers a fleet of hydropower dams that export electricity to Thailand, Vietnam + beyond, branding Laos as the region's renewable battery. Luang Prabang, a UNESCO World Heritage town of gilded Buddhist temples, sits at the confluence of the Mekong + Nam Khan; the megalithic Plain of Jars near Phonsavan remains one of Asia's great archaeological mysteries; Vang Vieng is a backpacker + adventure hub on the Nam Song.
A Lao phone number in international format is written as +856 [area code without 0] [local]. Example: +856 21 234 567 for Vientiane (021 234 567 domestic), +856 71 234 567 for Luang Prabang, +856 20 XXXX XXXX for a Unitel or Lao Telecom mobile.
Lao mobile numbers all start with 20 (020 domestically; +856 20 internationally). Drop the leading 0 internationally. Landline area codes are 2 digits (21 Vientiane, 71 Luang Prabang); mobiles are the 8-digit 20-series.
From the That Luang stupa in Vientiane to the temples of Luang Prabang, every Lao number lives behind a +856. Pick the area code that matches your customer city.
Every country uses a different exit code before +856. From any mobile, + replaces the exit code — so +856 21 234 567 works worldwide. Always drop the leading 0 from Lao numbers.
