Indonesia voice guidelines
Voice calling guidelines for Indonesia (ID), covering reachability, caller ID formats, DTMF support, and emergency services.
Locale overview
| Field | Value |
|---|---|
| Country | Indonesia |
| ISO code | ID |
| Region | Asia-Pacific |
| Dialing code | +62 |
Reachability
| Call type | Inbound | Outbound |
|---|---|---|
| Domestic | Supported | Supported |
| International | Supported (not guaranteed) | Supported |
| Toll-free | Supported | Not supported |
Outbound calls from toll-free numbers are not permitted.
To improve outbound call delivery within Indonesia, spread traffic across multiple originating numbers rather than concentrating calls from a single number. Using an Indonesian local number as the outbound caller ID (CLI) is strongly recommended for best results.
