Area Code 251 – Bogor

Overview of Area Code 251 (Bogor, Indonesia)

Area code 251 is a geographic National Destination Code (NDC) assigned to the city of Bogor and its surrounding metropolitan area in West Java, Indonesia. Bogor is a significant urban center located approximately 60 kilometers south of Jakarta, known for its cooler climate, the Bogor Botanical Gardens, and its role as a satellite city within the Greater Jakarta metropolitan area. The code covers the administrative city of Bogor (Kota Bogor) as well as the regency (Kabupaten Bogor), including districts such as Cibinong, Depok (partially), and other adjacent areas that fall under the Bogor numbering plan area.

In the Indonesian national numbering plan, area codes are used for fixed-line (PSTN) services. The complete international dialing format for a Bogor landline number is +62 251 XXXX XXXX, where the local number typically consists of 7 to 8 digits after the area code. When dialing domestically from another part of Indonesia, you must include the trunk prefix 0 before the area code, resulting in 0251 XXXX XXXX. For example, a Bogor landline number might be 0251 8312345 (domestic) or +62 251 8312345 (international).

Local Dialing and Overlay Considerations

Within the Bogor area, local calls between landlines in the same numbering area can be made using only the 7- or 8-digit subscriber number without the area code. However, due to the expansion of the subscriber base, some areas have introduced 8-digit local numbers. It is essential to verify the exact number of digits when dialing. As of recent updates, no overlay area code has been introduced for Bogor; the 251 code remains the sole geographic code for the region. Callers from outside Indonesia should replace the leading zero with the country code +62.

Caller Instructions

• Domestic callers (outside Bogor): Dial 0251 followed by the subscriber number. Example: 0251 8312345.
• Local callers (within Bogor): Dial the subscriber number directly (without 0251). Example: 8312345.
• International callers: Dial your country's exit code, then 62 (Indonesia's country code), then 251, then the subscriber number. Example: +62 251 8312345.

Bogor's fixed-line services are provided by PT Telkom Indonesia and other licensed operators. Mobile numbers in Indonesia are non-geographic and begin with prefixes such as 0811, 0812, 0813, etc., and are not associated with area code 251. When calling a Bogor landline from a mobile phone, you must include the area code (0251) even if you are in the same city, unless you are using a fixed-line phone within the local calling area.

Importance for Businesses and Residents

For businesses operating in Bogor, having a local landline number with the 251 code establishes a local presence and can be more cost-effective for customers calling from within the region. For international businesses, understanding the correct dialing format ensures seamless communication with partners, suppliers, and clients in Bogor. As Indonesia continues to develop its telecommunications infrastructure, area code 251 remains a stable and essential part of the national numbering plan.
