Overview of Area Code 336 (Jember, Indonesia)
Area code 336 is a geographic National Destination Code (NDC) assigned to the Jember region in East Java, Indonesia. It covers the administrative city of Jember and its surrounding regency, including districts such as Kaliwates, Sumbersari, Patrang, and Ajung. This code is part of the Indonesian public switched telephone network (PSTN) and is used for fixed-line telephony services.
Dialing Formats
When calling a fixed-line number in Jember, the dialing format depends on the caller's location:
- Local calls (within Jember): Dial the subscriber number directly, typically 7 to 8 digits, without the area code. For example, if the local number is 1234567, dial 1234567.
- National calls (from other parts of Indonesia): Dial 0 followed by the area code and subscriber number. For example, to call the same number from Jakarta, dial 0336 1234567.
- International calls (from outside Indonesia): Dial the international access prefix (e.g., 00 or +), then Indonesia's country code 62, followed by the area code without the leading zero, and the subscriber number. For example, from the United States, dial 011 62 336 1234567 or +62 336 1234567.
Numbering Structure
Fixed-line numbers in the 336 area code typically have a total length of 8 to 9 digits when including the area code (excluding the trunk prefix 0). The subscriber number length may vary, but the national significant number (NSN) is usually 9 to 10 digits, including the area code. The exact length can depend on the specific telephone exchange and the number of lines in the area.
Overlay and Regulatory Notes
As of the latest ITU-T E.164 guidelines, the 336 area code is not part of an overlay plan; it is the sole geographic code for Jember. However, the Indonesian telecommunications regulator (BRTI) has introduced number portability for fixed-line services, allowing subscribers to retain their numbers when switching providers, which may affect routing but not the dialing format.
Practical Guidance for Callers
For local callers, always omit the area code when dialing within Jember. For international callers, remember to drop the leading zero from the area code when using the +62 country code. Ensure you have the correct subscriber number, as fixed-line numbers in Indonesia are not mobile and are tied to a physical address.
