Area Code 374 – Bima

Overview of Area Code 374

Area code 374 is a geographic National Destination Code (NDC) within the Indonesian numbering plan, assigned to the city of Bima and its surrounding regency on the eastern coast of Sumbawa Island, West Nusa Tenggara (Nusa Tenggara Barat) province. This code follows the ITU-T E.164 international dialing standard, where the full international format for a fixed-line number in Bima is +62 374 XXX XXXX (with the leading trunk prefix '0' omitted).

Geographic Coverage and Administrative Jurisdiction

The 374 area code serves the administrative jurisdictions of Bima City (Kota Bima) and Bima Regency (Kabupaten Bima), including notable districts such as Rasanae Barat, Mpunda, and Woha. The region is a significant economic and cultural hub on Sumbawa, with the Port of Bima facilitating trade and ferry connections to Lombok and Flores. Local fixed-line services are predominantly provided by PT Telkom Indonesia, the incumbent operator, though alternative licensed operators may offer services in the area.

Dialing Formats and Caller Instructions

For callers within Indonesia, dialing a Bima fixed-line number requires the trunk prefix 0 followed by the area code and the subscriber number: 0 374 XXX XXXX. For example, to call a Bima landline with the subscriber number 123 4567, a domestic caller would dial 0374 123 4567. International callers must replace the trunk prefix with Indonesia's country code +62, resulting in +62 374 123 4567. When dialing from a mobile phone, the same international format applies, but the leading '+' may be replaced with the local international access code (e.g., '011' in the US, '00' in most countries).

Numbering Structure and Overlay Considerations

Bima fixed-line numbers typically consist of 7 to 8 digits after the area code, depending on the operator's allocation. As of the latest ITU-T national numbering plan, there is no overlay code for the 374 area; the code remains exclusively assigned to Bima and its environs. However, subscribers may have migrated to VoIP-based fixed lines, which do not alter the dialing format but may affect call quality and routing. For emergency services, callers should use the national emergency numbers (e.g., 110 for police, 118 for ambulance) regardless of the area code.

Practical Tips for Callers

• Always verify the subscriber number length before dialing; omitting a digit may result in a misdialed call.
• When calling from overseas, check with your service provider for international calling rates to Indonesia, as charges vary.
• For fax or modem connections, ensure the line is analog; some VoIP services may not support such transmissions reliably.
