Area Code 541 – Samarinda/Tenggarong

Geographic Coverage and Administrative Jurisdiction

The +62 541 country and area code combination corresponds to a geographic numbering plan area within the Republic of Indonesia, specifically allocated to the municipalities of Samarinda and Tenggarong in the province of East Kalimantan (Kalimantan Timur). Samarinda serves as the provincial capital and is the primary city covered by this code, while Tenggarong, the seat of Kutai Kartanegara Regency, is also included within the same local calling area. The code covers the administrative districts of Samarinda City (Kota Samarinda) and parts of Kutai Kartanegara Regency, including the urban and suburban zones surrounding these centers.

Dialing Formats and Caller Instructions

For callers within Indonesia, the area code is dialed with a leading trunk prefix 0, followed by the area code and the subscriber number. The national significant number (NSN) for fixed-line numbers in this region is typically 8 digits, excluding the trunk prefix. The format is: 0 541 XXX XXXX.

For international callers, the country code +62 replaces the trunk prefix, and the area code is used without the leading zero. The international format is: +62 541 XXX XXXX. For example, a fixed-line number in Samarinda might be dialed as +62 541 123 4567 from abroad, or 0541 123 4567 from within Indonesia.

Local calls within the same area code (Samarinda/Tenggarong) can be made using only the 7-digit subscriber number (without the area code) in most cases, though this may vary depending on the operator and the implementation of local dialing. However, for clarity and to avoid misdialing, it is recommended to always use the full national format when dialing from mobile phones or VoIP services.

Overlay Considerations and Numbering Plan

Currently, no overlay code has been introduced for the Samarinda/Tenggarong area; the 541 code remains the sole geographic code for this region. Subscriber numbers are allocated by the Indonesian Telecommunication Regulatory Authority (BRTI) to local fixed-line operators, including Telkom Indonesia and other licensed PSTN providers. As with all Indonesian geographic numbers, the code is used exclusively for fixed-line services, and mobile numbers in the area use separate non-geographic prefixes (e.g., 0811, 0812, etc.) that are not tied to location.

Practical Guidance for Callers

When calling a Samarinda or Tenggarong fixed-line number from a mobile phone within Indonesia, it is essential to include the trunk prefix and area code (e.g., 0541) even if you are physically located in the same city, as mobile networks do not interpret local 7-digit dialing. For international callers, always use the plus sign (+) or the international access code of your country, followed by 62 and the area code without the leading zero. Ensure you have the correct 7-digit subscriber number, as numbers in this region are not portable across geographic areas; they remain tied to the physical location of the line.
