📍 Geographic Location of Probolinggo
Geographic Overview
Area code 335 is a geographic National Destination Code (NDC) assigned to the Probolinggo region in East Java, Indonesia. It covers the municipality of Probolinggo (Kota Probolinggo) and the surrounding regency (Kabupaten Probolinggo), including districts such as Kraksaan, Paiton, and Besuk. The code is part of the Indonesian national numbering plan under ITU-T E.164, with the country calling code +62.
Dialing Formats
When calling a fixed-line number in Probolinggo from within Indonesia, subscribers dial the trunk prefix 0, followed by the area code 335, and the subscriber number (typically 5 to 7 digits). The complete national significant number (NSN) is 8 to 10 digits, including the leading 0. For example, a local number might be dialed as 0335-XXXXX.
From outside Indonesia, callers must use the international prefix (e.g., 00 or +), followed by the country code 62, then the area code without the leading 0, and the subscriber number. For instance, if the local number is 0335-12345, the international format would be +62 335 12345.
Local and International Calling Instructions
- Local callers within Probolinggo: For calls within the same area code, it is often possible to dial only the subscriber number, depending on the local exchange configuration. However, for clarity and to avoid misdialing, it is recommended to use the full national format (0-335-XXXXX).
- Callers from other Indonesian cities: Dial 0-335-XXXXX (e.g., 0-335-12345).
- International callers: Dial your country's exit code, then 62-335-XXXXX (e.g., +62-335-12345).
Overlay and Numbering Considerations
As of the latest ITU-T operational bulletin, there is no overlay code for the Probolinggo area. The area code 335 is exclusively used for geographic fixed-line services. Subscriber numbers within this code are allocated to local fixed-line operators, primarily PT Telkom Indonesia. The numbering plan is closed, meaning that the length of the subscriber number may vary, but the total length of the national significant number (0-335-XXXXX) is fixed at 10 digits (including the leading 0).
For businesses and individuals, it is essential to use the correct format to avoid call failures. When storing numbers in international databases, always use the +62 format without the leading 0, as per E.164 guidelines.
