Sending SMS to Indonesia

Indonesia is a high-volume, price-sensitive market spread across thousands of islands and four major networks, which makes route quality more variable than in a single-operator country. Masking rules differ by operator, so a sender ID that works on Telkomsel may be rewritten on another network.

Sender ID rules for +62

Alphanumeric sender IDs require registration and behave differently per operator; some routes replace unregistered IDs with a numeric long code.

Number format+62 8XX XXXX XXXX — mobile numbers begin 08 nationally.

Delivers across every major network in Indonesia: Telkomsel, Indosat Ooredoo Hutchison, XL Axiata, Smartfren.

What people send most: OTP for fintech and e-wallets · Ride-hailing and delivery notifications · E-commerce promotions.

Message length: under the standard SMS encoding, a segment typically holds 160 GSM-7 characters, or 70 once a message uses Unicode — Arabic, Chinese, Cyrillic, emoji. Longer messages split into several segments automatically and are billed per segment; exact limits are confirmed for Indonesia as part of onboarding.

What businesses send in Indonesia

OTP for fintech and e-wallets

Time-critical — it has to land in seconds, which is the reason SMS still wins here over push or email.

Ride-hailing and delivery notifications

Keeps the recipient's attention without needing an app open, for the moment they actually care about the update.

E-commerce promotions

Needs clear consent and a working opt-out — the requirements above apply directly to this traffic.

Dialling

How to dial Indonesia

Every part of the number, laid out separately, then the same thing written the way an API expects it.

+Exit

62Country code

8XX XXXX XXXXNational number

+62 — +62 8XX XXXX XXXX — mobile numbers begin 08 nationally.

From abroad, replace your exit code with +, then 62, then the national number — dropping the national trunk prefix if the country uses one (a leading 0 in most, though not in the +1 numbering plan). Store numbers in E.164 (+62…) and they work from any country and any API.
