East Timor country code +670 — call East Timor & get a number.

What is the country code for East Timor?

Most countries have held the same ITU dialing code since international numbering was standardized. East Timor has not. Under Portuguese colonial administration, the territory was assigned code +670 as Portuguese Timor. Following Indonesia's 1975 invasion and annexation, the territory was folded into the Indonesian numbering plan and dialed using Indonesia's +62 country code for the next 24 years.

When Indonesian forces withdrew in September 1999 amid a UN-supervised independence referendum, the territory needed its own code again — but by then +670 had, in the interim, also been assigned for use by the Northern Mariana Islands' NANP numbering, creating a brief international numbering conflict before the ITU restored +670 specifically to East Timor as the territory moved toward full independence on May 20, 2002.

Few countries anywhere have had their international dialing identity swing between three different systems — colonial, occupying, and independent — within a single generation. It's a small but telling window into East Timor's turbulent 20th-century history, visible in something as mundane as a phone number.

East Timor time zone

Timor-Leste operates on UTC+9 year-round, with no daylight saving time observed. This places it in the same time zone as Japan, South Korea, and most of Indonesia's eastern regions, but 1 hour ahead of the Philippines and China, and roughly 13 to 14 hours ahead of the US East Coast depending on American DST status.

Because Timor-Leste's offset never changes, once you've confirmed the offset against your own city, it stays correct indefinitely — the only variable is whether your own city shifts its own clock seasonally.

Why this matters for business: if you're coordinating call center hours, IVR schedules, or SLA windows against Timor-Leste, the math you calculate once remains valid — Timor-Leste's side of the equation never changes.

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

Why businesses get a East Timor virtual number

Timor-Leste's mobile market went from a single state-linked monopoly to a genuinely competitive three-operator market within about a decade. Timor Telecom began commercial service in 2003 under an exclusive license that was terminated early in 2012 to open the market to Telkomcel and later Telemor — a rapid modernization for a country that had to rebuild its entire telecommunications infrastructure from almost nothing after 1999.

As a mountainous, partially archipelagic nation, all three mobile operators still rely heavily on satellite connectivity for their international uplink, which keeps data costs relatively high and connection speeds slower than in better-connected Southeast Asian markets. Internet adoption estimates vary by source, ranging from roughly 13% (ITU figures) to over 27% (World Bank, more recent years) of the population — a wide range that itself reflects how quickly connectivity has been changing.

Timor-Leste's business culture reflects its Portuguese colonial heritage layered with Southeast Asian and Catholic traditions — the country is one of the most heavily Catholic nations in Asia, and religious holidays, particularly around Easter and All Souls' Day, significantly affect business availability. Meetings tend to move at an unhurried pace by Western standards, and relationship-building before business discussion is customary.
