Area Code 755 – Solok

Geographic Overview

The +62 755 area code is a geographic National Destination Code (NDC) assigned to the city of Solok and its surrounding regency (Kabupaten Solok) in the province of West Sumatra, Indonesia. This region is located in the highlands of Sumatra, approximately 60 kilometers northeast of Padang, the provincial capital. The code covers Solok City, the administrative and economic hub, as well as nearby towns and rural areas within the regency, including Aripan, Koto Baru, and Lubuk Selasih. The service area is part of the PSTN (Public Switched Telephone Network) and is served by both fixed-line operators and, in some cases, fixed-wireless access services.

Dialing Formats

When calling a landline in Solok from within Indonesia, subscribers must dial the trunk prefix '0' followed by the area code and the subscriber number. The national format is: 0 755 XXX XXXX (where the subscriber number typically consists of 7 to 8 digits, depending on the operator and service type). For example, a local number might be dialed as 0755 1234567.

For international callers, the country code for Indonesia is +62, and the leading '0' of the trunk prefix is omitted. The international format is: +62 755 XXX XXXX. For instance, if the national number is 0755 1234567, an international caller would dial +62 755 1234567.

Calling Instructions

• Local callers (within Solok): For calls within the same area code, local numbers can often be dialed without the area code, depending on the operator's dialing plan. However, to ensure connectivity, it is recommended to dial the full national number (0755 XXX XXXX) for all calls, including local ones.
• National callers (from other Indonesian cities): Dial 0 755 XXX XXXX using any landline or mobile phone.
• International callers: Dial your country's international access prefix (e.g., 00 from many countries, or +), then 62 755 XXX XXXX.

Regulatory and Technical Notes

Area code 755 is part of the Indonesian national numbering plan, administered by the Ministry of Communication and Informatics (Kominfo) and the Indonesian Telecommunication Regulatory Authority (BRTI). It follows ITU-T E.164 recommendations. The code is exclusively geographic, meaning it is tied to the Solok region. Overlay codes are not currently in effect for this area, so the 755 code is the sole NDC for the region. Fixed-line numbers in Solok are typically used by residential and business subscribers, and are not portable to mobile networks. Calls to 755 numbers are charged based on the caller's location and service provider, with national calls subject to standard domestic tariffs.

For businesses and individuals seeking to establish a presence in Solok, obtaining a local fixed-line number with the 755 code can enhance local credibility and accessibility. However, with the rise of mobile and VoIP services, many residents also use mobile numbers, which have their own prefixes (e.g., 0812, 0852, etc.) and are not tied to geographic locations.
