Laos numbering plan & how to dial
Under country code +856, Laos numbers follow an open plan built from a 2-digit area or mobile prefix and a 7-digit subscriber line — 9 digits in all. A domestic "0" typically precedes the prefix, but that digit is dropped when dialing Laos internationally.
3 major networks cover Laos (Lao Telecom, Unitel, ETL), against 62% internet penetration. VoIP is restricted and Ministry of Information, Culture and Tourism (MICT) / Ministry of Technology and Communications licenses only approved operators. Because Lao is the primary language and LAK the local currency, both should inform IVR scripts, SMS content, and support hours.
Asian markets range from fully liberalised to licensed-only VoIP, so compliant routing and correct local caller ID have an outsized effect on answer rates.
Skipping the exit code
Reaching Laos from the US requires the 011 exit code ahead of +856 — skip it and the call won't connect.
Keeping the national trunk "0"
If a Laos number is written with a leading 0 for domestic use, omit that 0 after the +856 country code when calling from abroad.
Ignoring the time difference
UTC+7 governs local business hours in Laos; confirm the time there before placing the call.
Using non-compliant routes
Ministry of Information, Culture and Tourism (MICT) / Ministry of Technology and Communications restricts VoIP into Laos — unlicensed grey routes get blocked or dropped, so compliant termination is the only reliable path.
Restricted — MICT licensed only
Regulated by Ministry of Information, Culture and Tourism (MICT) / Ministry of Technology and Communications
- VoIP services are tightly controlled and require government-issued licenses.
- Unauthorized VoIP bypass using SIM boxes is illegal and actively monitored.
- Internet and VoIP content is subject to government monitoring under Lao cybercrime law.

FAQ
Calling Laos — frequently asked questions
Yes — Ministry of Information, Culture and Tourism (MICT) / Ministry of Technology and Communications only licenses approved operators in Laos, so unlicensed routes risk being blocked or dropped mid-call. Twiching terminates strictly over compliant, licensed paths to avoid that risk.
Over Tier-1 direct interconnects with major local networks like Lao Telecom, rather than lower-quality wholesale transit routes. That direct-carrier approach is what keeps delivery rates and call clarity high.
The major networks in Laos are Lao Telecom, Unitel, ETL. Twiching interconnects with Tier-1 carriers for direct delivery to these networks, rather than routing through cheaper wholesale transit that can degrade call quality.
The US exit code is 011 for any international call, including to Laos. It comes right before the +856 country code, and Twiching adds both automatically when you dial from the app, so you only need to enter the local number.
Yes — Laos numbers often carry a domestic leading 0 that should be dropped once you've dialed the +856 country code from abroad. Keeping that 0 in is one of the most common reasons an international call to Laos fails to connect.
Vientiane is the capital of Laos. A local +856 number is recognisable to callers there and nationwide, which is part of why presenting local caller ID tends to improve answer rates across the whole country, not just the capital.
