Area Code 338 – Situbondo

Overview of Area Code 338 (Situbondo)

Area code 338 is a geographic National Destination Code (NDC) assigned to the Situbondo Regency in the province of East Java (Jawa Timur), Indonesia. This code is part of the Indonesian public switched telephone network (PSTN) and follows the ITU-T E.164 international numbering standard. When dialing a fixed-line number in Situbondo from abroad, the full international format is +62 338 XXX XXXX, where the leading '0' of the domestic trunk prefix is omitted.

Geographic Coverage and Administrative Jurisdiction

The 338 area code serves the entire Situbondo Regency, which is located on the northern coast of East Java, bordering the Madura Strait. Key administrative districts (kecamatan) covered include Situbondo (the capital), Panarukan, Asembagus, Banyuglugur, and Suboh. The code also covers surrounding towns and villages within the regency, providing fixed-line services to residential, business, and government subscribers.

Dialing Formats and Caller Instructions

For callers within Indonesia, the domestic dialing format is 0338 XXX XXXX. The trunk prefix '0' is used for all domestic long-distance calls. For example, to call a landline in Situbondo from Jakarta, you would dial 0338 123 4567. For international callers, the country code +62 replaces the trunk prefix, so the number becomes +62 338 123 4567. When dialing from a mobile phone in Indonesia, the same domestic format applies, but it is essential to include the area code even when calling from within the same region, as local numbers are not valid without it.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 338 area. Subscribers in Situbondo use seven-digit local numbers (after the area code), resulting in a total of 12 digits when including the country code and trunk prefix (i.e., +62 338 XXX XXXX). The numbering plan is managed by the Indonesian Telecommunication Regulatory Authority (BRTI) under the Ministry of Communication and Informatics. Fixed-line numbers are allocated to incumbent operators such as Telkom Indonesia, as well as other licensed PSTN providers.

Practical Usage and Tips

When calling a Situbondo landline from abroad, always replace the leading '0' with +62. For example, a local number 0338 765 4321 becomes +62 338 765 4321. If you are traveling in Indonesia and need to call a Situbondo number, ensure you include the area code even if you are dialing from a mobile phone, as mobile networks do not automatically add area codes. For international callers, check with your service provider for any specific dialing prefixes (e.g., 011 from the US, 00 from many European countries) before the country code.
