Area Code 462 – Atsugi, Kanagawa

Overview of Area Code 462

Area code 462 is a geographic National Destination Code (NDC) within the Japanese numbering plan, assigned to the Atsugi area in Kanagawa Prefecture. It covers Atsugi City and its surrounding regions, including parts of Isehara, Ebina, and Samukawa towns. This code is part of the greater Tokyo metropolitan area's telecommunications infrastructure, though it operates under the separate 0462 numbering block, which is distinct from the 03 Tokyo code.

Geographic Coverage and Administrative Jurisdiction

The 0462 area code serves the central and western portions of Kanagawa Prefecture, with Atsugi City as the principal city. Atsugi is a significant industrial and commercial hub, home to major technology companies and the Atsugi Naval Air Facility. The code also covers the northern part of Isehara City and the eastern part of Ebina City, as well as the town of Samukawa in Koza District. These areas are within the administrative jurisdiction of Kanagawa Prefecture, which is part of the Kanto region.

Dialing Formats and Caller Instructions

For local callers within the same area code, the national subscriber number is typically 7 digits, and local calls are made by dialing the 7-digit number without the area code. However, for calls from outside the 0462 area (but within Japan), the full national format is used: 0462-XXX-XXX. For international callers, the format is +81 462 XXX XXX (or +81-462-XXX-XXX). When dialing from abroad, the leading zero of the area code is dropped, so 0462 becomes 462 after the country code. For example, to call a number in Atsugi from the United States, one would dial 011 81 462 XXX XXX (or +81 462 XXX XXX on a mobile phone).

Overlay Considerations and Numbering Changes

Currently, there is no overlay code for the 0462 area, meaning that the area code is not shared with another NDC. However, in recent years, Japan has implemented 10-digit dialing for all calls to mobile and IP phones, but geographic numbers like those in 0462 still use the traditional format. It is important to note that some numbers in the Atsugi area may be assigned to VoIP services, which are non-geographic and may not be tied to a physical location, but they still use the 0462 code for routing purposes.

Practical Tips for Callers

When calling from a fixed line in Japan to an 0462 number, you must dial the area code even if you are within the same region, unless you are in the same charging group. For international callers, always replace the leading zero with the country code and ensure you have the correct number of digits. For example, a typical Atsugi number might be +81 462 12 3456. If you are unsure about the number length, note that Japanese geographic numbers are usually 10 digits in total (including the area code without the leading zero). Always verify the number with the recipient to avoid misdialing.
