Area Code 562 – Singkawang/Sambas/Bengkayang

Overview of Area Code +62 562

Area code 562 is a geographic National Destination Code (NDC) within the Indonesian numbering plan, assigned to the western coastal region of West Kalimantan (Kalimantan Barat) on the island of Borneo. Specifically, it serves the municipalities of Singkawang, Sambas, and Bengkayang, along with their surrounding regencies. This code is part of the closed dialing plan used in Indonesia, where the full national significant number (NSN) consists of the area code followed by a subscriber number, totaling 9 to 10 digits when including the leading trunk prefix '0'.

Geographic Coverage and Administrative Jurisdiction

The 562 area code covers a strategically located region bordering Malaysia (Sarawak) and the South China Sea. Key cities and administrative areas include:

• Singkawang – a city known for its multicultural heritage and Chinese-Indonesian communities.
• Sambas Regency – known for its traditional Malay culture and agricultural production.
• Bengkayang Regency – a border area with significant natural resources.

These areas are served by fixed-line operators (primarily Telkom Indonesia and other licensed PSTN providers). The code is strictly geographic, meaning the number is tied to a physical location and does not move with the user.

Dialing Formats and Instructions

Understanding the correct dialing procedure is essential for both domestic and international callers.

• Domestic Calls (within Indonesia): Dial the trunk prefix 0, followed by the area code 562, and then the subscriber number. For example, if the local subscriber number is 12345, dial 0562 12345 from any phone in Indonesia.
• International Calls (from outside Indonesia): Dial the international access prefix (e.g., 00 from most countries, or +), then Indonesia's country code 62, followed by the area code 562 (without the leading 0), and the subscriber number. For the same example, dial +62 562 12345.

Note that the subscriber number length may vary, but the total NSN (including the area code) is typically 8 digits for this region. Always verify the exact number with the called party.

Overlays and Numbering Changes

Currently, there is no overlay code in the 562 area. However, as demand for fixed-line services evolves, the Indonesian Telecommunication Regulatory Authority (BRTI) may introduce additional digits or overlays. Callers should always use the full 10-digit format (including trunk prefix) for domestic calls to ensure proper routing.

Practical Tips for Callers

• For local calls within Singkawang, Sambas, or Bengkayang, you may still need to dial the area code if you are using a mobile phone or if your fixed-line operator requires it. Always check with your service provider.
• When calling from a mobile phone in Indonesia, it is common practice to include the area code even for local numbers to avoid misrouting.
• For international callers, ensure you drop the leading '0' of the area code when using the +62 country code.

This area code is an integral part of Indonesia's E.164 numbering plan, ensuring reliable and efficient telecommunication services for both residents and businesses in the region.
