📍 Geographic Location of Sendai, Miyagi
Geographic Overview
The +81 227 area code is a geographic National Destination Code (NDC) assigned to the Sendai metropolitan area in Miyagi Prefecture, Japan. Sendai, the largest city in the Tohoku region, serves as the administrative and economic hub, with the code covering the city's central wards (Aoba, Miyagino, Wakabayashi, Taihaku, and Izumi) as well as surrounding municipalities such as Tagajo, Natori, and parts of Tomiya. This numbering area is managed under the Japanese Ministry of Internal Affairs and Communications (MIC) and is operated by NTT East, with alternative carriers also providing services.
Dialing Formats
When calling a landline in Sendai from within Japan, you must dial the trunk prefix 0 followed by the area code and subscriber number. For example, to reach a local number such as 123-4567, you would dial 022-123-4567 from outside the area. However, from within the same area code, you may omit the area code and simply dial 123-4567 (local call).
For international callers, the country code +81 replaces the trunk prefix, and the leading '0' of the area code is dropped. Thus, the same number would be dialed as +81 22 123 4567 from overseas. Note that the area code is often written as 022 in domestic format, but the international format omits the initial zero.
Numbering Structure and Overlays
Subscriber numbers in the 227 area code are seven digits long, making the total national significant number (NSN) length 10 digits (including the leading zero). There are no overlay codes in this region; the 227 code is the sole geographic code for the Sendai area. However, due to number portability, a landline number may be routed to a VoIP or mobile service, but the geographic identity remains.
Caller Instructions
For local callers within Sendai, dial the 7-digit subscriber number directly. For callers elsewhere in Japan, dial 022 followed by the subscriber number. For international callers, dial +81 22 followed by the subscriber number. Be aware that some businesses may list their number in international format, so always confirm the correct format before dialing.
