Area Code 1466 – Erimo, Hokkaido

Geographic Overview

The area code 1466 is a geographic National Destination Code (NDC) assigned to the town of Erimo, located in the Hidaka Subprefecture of Hokkaido, Japan. This code is part of the Japanese telephone numbering plan, which adheres to ITU-T E.164 standards. Erimo is a coastal town known for its dramatic cliffs and the Cape Erimo, a prominent landmark. The code covers the administrative area of Erimo Town, including its central districts and surrounding rural communities. For callers within Japan, the local dialing format is 01466-X-XXXX, where X represents the subscriber number. When dialing from abroad, the international format is +81 1466-X-XXXX, with the leading zero of the NDC omitted. It is important to note that this is a geographic code, meaning that the number is tied to a physical location and is typically associated with fixed-line PSTN services, although some VoIP providers may offer numbers with this code.

Dialing Instructions

For local callers within Erimo, dialing the full 01466 number is required, as there are no shorter local dialing procedures. For callers from other parts of Japan, dial 01466-X-XXXX. For international callers, dial the international access prefix (e.g., 011 from the US, 00 from most countries) followed by 81 (Japan's country code), then 1466, and the subscriber number. For example, a call to a subscriber number 123456 would be dialed as +81 1466-123456 from abroad. It is essential to omit the leading '0' of the NDC when dialing internationally.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for the 1466 area. The code serves a relatively small population, and number exhaustion is not a current concern. However, with the ongoing migration of fixed-line services to IP-based networks, some numbers with this code may be assigned to VoIP services, but the geographic association remains unchanged for emergency services and caller location identification. When calling from a mobile phone within Japan, the same dialing format applies, and no additional prefixes are required.

Practical Information

For businesses and residents in Erimo, having a local number with the 1466 code establishes a strong local presence and can be important for local customer trust. For those outside Japan, understanding the correct international dialing format is crucial to avoid call failures. Always verify the subscriber number length, as it may vary, but the total number of digits after the country code (81) and NDC (1466) is typically 6 to 7 digits, making the full international number 10 to 11 digits long.
