Overview of Area Code 2545

Area code 2545 is a geographic National Destination Code (NDC) within the Japanese numbering plan, assigned to the city of Murakami in Niigata Prefecture. It covers the former Murakami city area, including the central urban district and surrounding administrative zones. The code is used for fixed-line (PSTN) services, and calls to this region are routed via the Nippon Telegraph and Telephone (NTT) network.

Geographic Coverage and Administrative Jurisdiction

The 2545 area code serves the northern part of Niigata Prefecture, bordering Yamagata Prefecture. The primary city is Murakami, which is the administrative seat of Murakami City. The area includes the former towns of Arakawa, Asahi, and Sanpoku, which were merged into the expanded Murakami City in 2008. The region is known for its salmon fishing, traditional crafts, and scenic coastline along the Sea of Japan.

Dialing Formats

When calling a fixed-line number in Murakami from within Japan, you must dial the area code (without the leading 0) followed by the subscriber number. The full national format is 0-2545-X-XXXX, where X-XXXX is the 5-digit subscriber number. For example, a local number might be 0-2545-12-3456.

For international callers, the format is +81-2545-X-XXXX (drop the leading 0). For instance, if the local number is 0-2545-12-3456, you would dial +81-2545-12-3456 from overseas.

Local and Foreign Caller Instructions

Within Japan, callers from other area codes must dial 0-2545-X-XXXX. Calls from mobile phones or VoIP services may require the area code even when calling within the same region, depending on the service provider. For callers outside Japan, the international access code of their country (e.g., 011 from the US) must be used before the country code and area code.

Overlay Considerations

As of the current numbering plan, there is no overlay code for 2545. The area code is unique to the Murakami region, and no additional area codes have been assigned to the same geographic area. This simplifies dialing, as there is no need for 10-digit dialing within the region.

Important Notes

All numbers within the 2545 area code are geographic and tied to physical locations. They are not portable to other regions, but fixed-line number portability within the same area is possible. For emergency services, dial 110 (police) or 119 (fire/ambulance) regardless of the area code.
