How to read a Laos phone number

A Laos number is +856 followed by 8 digits. Knowing which of those digits mark a mobile is what tells you what the call will cost before you place it.

Inside Laos, numbers are dialled with a leading 0. Drop it when calling from abroad — keeping it is the single most common reason an international call fails.

Prefix ranges still identify a line as mobile or fixed even where a number has been ported between operators, because the mobile and fixed blocks are separate and numbers do not move between them. Operator identification from a prefix, by contrast, stopped being reliable once portability arrived.

Other Asian destinations, cheapest first

Rates vary by more than a factor of ten inside a single region, because each one is set by what the operator at the far end charges to accept the call. Taiwan is currently the cheapest place we publish a rate for near Laos.

Frequently asked questions

What is the country code for Laos?

The country code for Laos is +856. Dial this after the exit code (or use + on a mobile).

What does a Laos phone number look like?

A Laos number is written as +856 21 123 456: the country code +856 followed by 8 digits. That total is fixed by the national numbering plan, so a number with one digit missing is a typo rather than a shorter valid number.

How can I tell if a Laos number is a mobile?

By its leading digits. In Laos, a national number of 8 digits beginning with 20 is a mobile. That still works after a number has been ported between operators, because mobile and fixed-line blocks are separate ranges and numbers do not move between them.

Do I need to drop the leading 0 when calling Laos?

Yes. Laos uses 0 as a trunk prefix for domestic calls. When dialing internationally, drop the leading 0 from the local number.
