這 寮國國家代碼是+856 — 透過寮國電信 (LTC)、Unitel + ETL 的行動覆蓋，涵蓋湄公河中心地帶約 750 萬寮人，覆蓋東南亞唯一的內陸國家。從萬象商務到瑯勃拉邦旅遊，寮國銀行OTP（BCEL，寮國發展銀行）的預期都是+856。
寮國被國際電聯分配為+856－將其與東南亞大陸一起置於第8區。萬象 (021) 坐落於湄公河沿岸，與泰國隔海相望。
寮國使用 +856 國家代碼，與泰國 +66、越南 +84、柬埔寨 +855、馬來西亞 +60 + 緬甸 +95 一起位於 ITU 8 區。 「856」字尾是寮國獨有的－東南亞唯一的內陸國家，周圍環繞著泰國、越南、柬埔寨、中國+緬甸。
寮國的電信業受以下機構監管 科技及通訊部 （MTC）。三個主要營運商：寮國電信（LTC，部分國有的現有營運商）、Unitel（Star Telecom - Viettel 合資企業，用戶數量最大）+ ETL（寮國電信企業）。所有老撾手機均使用 20 前綴。
寮國區號在國內帶有前導 0（在國際上被丟棄）。主要：<b>021</b>萬象（首都）、<b>071</b>瑯勃拉邦（聯合國教科文組織城鎮）、<b>041</b>沙灣拿吉、<b>031</b>巴色（佔巴塞）。寮國手機皆以 <b>20</b> 開頭 — 國際上寫作 +856 20 XXXX XXXX（國內寫作 020 XXXX XXXX）。
寮國有「東南亞電池」之稱。 湄公河是該國的脊梁，為一系列水力發電大壩提供動力，這些水壩將電力出口到泰國、越南等其他國家，使寮國成為該地區的可再生電池。瑯勃拉邦是聯合國教科文組織世界遺產小鎮，擁有鍍金的佛教寺廟，坐落在湄公河和南汗河的交匯處；豐沙灣附近的巨石缸平原仍然是亞洲最大的考古謎團之一；萬榮 (Vang Vieng) 是南宋 (Nam Song) 上的背包客和探險中心。
國際格式的寮國電話號碼寫為 +856 [area code without 0] [local]。例子： +856 21 234 567 萬象（021 234 567 國內）， +856 71 234 567 對於瑯勃拉邦來說， +856 20 XXXX XXXX 適用於聯合電信 (Unitel) 或寮國電信 (Lao Telecom) 手機。
寮國手機號碼全部開頭 20 （020 國內；+856 20 國際）。國際上去掉前導0。固定電話區號為 2 位數（21 萬象、71 瑯勃拉邦）；手機是 8 位元 20 系列。
從萬象的塔鑾佛塔到瑯勃拉邦的寺廟，每個寮國號碼都位於+856後面。選擇與您的客戶城市相符的區號。
+856 之前每個國家使用不同的退出代碼。透過任何手機， + 替換退出代碼 - 所以 +856 21 234 567 在全球範圍內工作。始終刪除老撾數字中的前導 0。

+856 reaches the heart of mainland Southeast Asia — Vientiane business, Luang Prabang + Mekong tourism + the hydropower "battery of SE Asia". Lao banks (BCEL, Lao Development Bank) verify with +856 mobile OTPs.
Lao banks — BCEL (Banque pour le Commerce Extérieur Lao), Lao Development Bank, Joint Development Bank + the BCEL One app — verify with +856 mobile OTPs. A Lao number keeps you reachable for banking, mobile-money (U-Money, M-Money) + government services.
A +856 line connects you to Laos's tourism economy: UNESCO Luang Prabang, the Plain of Jars near Phonsavan, Vang Vieng adventure travel, the Vientiane riverfront + Mekong cruises. Tour operators, guesthouses + the Laos-China Railway all run on +856.
A 021 area code says "Vientiane — the capital on the Mekong, across from Thailand". It is the seat of government, the ASEAN secretariat liaison + most Lao corporate HQs. A 071 says Luang Prabang; 041 Savannakhet; 031 Pakse (Champasak).
Laos brands itself the "battery of Southeast Asia" — its Mekong + tributary hydropower dams export electricity to Thailand, Vietnam + Cambodia. A +856 number is essential for energy, infrastructure + cross-border trade businesses operating in the Lao power sector.
Laos runs on Indochina Time (ICT, UTC+7) all year with no daylight saving — the same clock as Thailand, Vietnam + Cambodia. Regional business hours across mainland SE Asia align cleanly with a +856 number.
As the only landlocked country in Southeast Asia, Laos is the land bridge between China, Thailand, Vietnam + Cambodia. The Laos-China Railway + Mekong corridors make a +856 line a gateway for logistics, trade + cross-border commerce.
