What is the country code for Laos?

Laos runs a country code — +856 — that covers a nation shaped less like a single dense grid of cities and more like a long ribbon following the Mekong River, from the mountainous north down to the Cambodian border in the south. Unlike many of its neighbors, Laos didn't build its mobile numbering plan around a patchwork of regional prefixes: nearly all mobile numbers in the country share a single nationwide prefix, 020, regardless of which operator issued the SIM or which province the subscriber lives in.

Landline numbers, by contrast, still carry the older province-based structure, with 021 identifying Vientiane and other codes (such as 041 for Champasak Province) identifying the rest of the country.

That split — one universal mobile prefix layered over a traditional province-code landline system — is the first thing to understand about dialing Laos, and it's a structure shared with several of Laos's Southeast Asian neighbors that modernized their mobile numbering separately from their legacy fixed-line plans.

Laos time zone

Laos sits in Indochina Time (ICT), UTC+7, year-round.

Here's what makes scheduling with Laos simpler than with many other international destinations: Laos does not observe daylight saving time, and never shifts its clock seasonally. The UTC+7 offset holds constant all year, matching Thailand, Vietnam, and Cambodia — so once you've confirmed the offset against your own city, you don't need to re-check it twice a year the way you would with a DST-observing country.

Why this matters for business: if you're coordinating call center hours, IVR schedules, or SLA windows against Laos, the math you do once stays correct indefinitely — the only variable is whether your own city shifts its clocks, not Laos's.

Common mistakes when calling Laos

Almost every failed international call is a formatting issue, not a network issue.

Why businesses get a Laos virtual number

Laos is the only landlocked country in Southeast Asia, bordered by Thailand, Vietnam, Cambodia, Myanmar, and China, with the Mekong River serving as both a geographic backbone and, for long stretches, the border with Thailand. That landlocked, river-oriented geography shaped a country where population and infrastructure cluster along the Mekong corridor rather than spreading evenly across the land.

It's also a strikingly diverse country ethnically and linguistically — Laos officially recognizes dozens of distinct ethnic groups, each often with its own language or dialect, even though Lao is the sole official language for government, education, and business.

For businesses and callers, the practical upshot of the numbering plan is convenience: because virtually every mobile number in the country shares the same 020 prefix, a single Laos virtual number reads as fully local no matter which province your customer, partner, or contact is calling from — there's no regional prefix mismatch to worry about, unlike in countries where mobile numbering is split by area.
