How Asia's Country Codes Are Organized, and How to Dial Across Them Without Errors

In short

Asian country codes are not random; they follow the numbering zones the ITU laid out decades ago, and knowing the zones makes unfamiliar numbers readable. This guide explains where zones 6, 8, and 9 fall, how exit codes differ across the region, and the mistakes that most often break calls.

Three Zones Cover Most of the Continent

Global numbering divides the world into zones by first digit. Southeast Asia and Oceania largely occupy zone 6, which is why Malaysia is +60, Indonesia +62, the Philippines +63, and Singapore +65. East Asia fills zone 8: Japan +81, South Korea +82, Vietnam +84, and China +86.

Zone 9 sweeps from Turkey through South Asia and the Middle East, giving India +91, Pakistan +92, and Sri Lanka +94. Smaller territories carry three-digit codes within these zones, such as Hong Kong +852, Macau +853, Cambodia +855, Taiwan +886, and Bangladesh +880.

Exit Codes Are Not Uniform in Asia

Callers inside Asia face more exit code variety than Europeans do. Japan dials 010 to go international, while most of the region uses 00 and Australia uses 0011. This trips up travelers who memorize one sequence and reuse it across borders.

The plus sign solves it. Entering a number as + followed by country code and subscriber number lets any mobile handset, and any browser dialer, apply the right routing regardless of where you are standing. Store every Asian contact in plus format once and stop thinking about exit codes.

Within each country a second layer of structure applies. Japan and Indonesia keep city codes for their fixed lines, Chinese mobiles all begin with 1, and Indian mobiles start with digits 6 through 9. Learning the destination's mobile pattern lets you spot a miscopied number before wasting a call.

The Mistakes That Break Calls

The classic error is keeping the domestic trunk zero after the country code. An Indian mobile written 098765 43210 dials internationally as +91 98765 43210, zero removed. The same rule applies in Indonesia, Pakistan, Thailand, and most of the region, so treat a 0 after the plus code as a red flag.

Length assumptions cause the rest. Chinese mobiles run eleven digits domestically, Japanese numbers ten, Singaporean numbers eight with no area codes at all. When a number looks too short or too long, verify against the destination country's format instead of padding or trimming digits yourself.

Half-hour and quarter-hour offsets add a final trap. India sits at UTC+5:30, Myanmar at UTC+6:30, and Nepal at UTC+5:45, so meeting times converted casually in whole hours arrive thirty or forty five minutes wrong. Convert precisely for any call that crosses these zones.

Calling Across the Region Affordably

Rates to Asia vary enormously by destination and by number type, since many Asian countries price mobiles above landlines. Comparing the per-minute rate for the specific country before dialing matters more here than in North America. A rate table check takes seconds and prevents surprises.

Browser calling keeps every route on one balance. StartACall connects to any Asian country code through WebRTC in Chrome, Safari, Firefox, or Edge, pay-as-you-go with no subscription and credits that never expire, useful when your calls spread across several countries in a month.

Frequently asked questions

Why do some Asian countries have three-digit codes?+

Two-digit codes went to early, high-traffic assignments like +81 Japan and +91 India. Later assignments within full zones received three digits, which is why Hong Kong is +852, Taiwan +886, and Bangladesh +880.

What exit code do I dial from Japan?+

010, followed by the destination country code and number. Japan is the notable exception to the 00 pattern common elsewhere in Asia, though the plus sign works on mobiles everywhere.

Do I keep the leading zero in Asian mobile numbers?+

Almost never. India, Indonesia, Thailand, Pakistan, and most of the region drop the trunk zero internationally. Singapore and Hong Kong have no trunk zero at all, so their numbers dial as written.

Are calls to Asian mobiles more expensive than landlines?+

In many countries, yes. Unlike North America, much of Asia assigns mobiles distinct ranges billed at different rates, so check the mobile rate for the specific country rather than assuming one price.

Can one service cover calls to every Asian country?+

Yes. A browser-based per-minute service applies its published rate per destination from a single credit balance, so calls to India, the Philippines, and China can share one account without separate plans.
