Geographic Coverage and Administration

Funabashi is a major city in the Greater Tokyo Area, located on the eastern shore of Tokyo Bay. The 4775 area code serves the central and northern districts of Funabashi, including areas such as Narashino (partially), Kamagaya, and Shiroi. The code is administered under the Japanese Ministry of Internal Affairs and Communications (MIC) and follows the ITU-T E.164 numbering plan.

Dialing Formats

Local calls (within the 4775 area): Dial the 7-digit subscriber number (XXXXXXX) without the area code. For example, to call a local number, simply dial 1234567.
National calls (from other areas in Japan): Dial 0-4775-XXXXXXX. For instance, from Tokyo, you would dial 04775 1234567.

Numbering and Overlay Considerations

Japanese area codes can have variable lengths. The 4775 code is a 4-digit area code, and the subscriber number is 7 digits, making a total of 11 digits when including the trunk prefix '0'. This is standard for many Japanese geographic codes. Currently, there is no overlay code for this area; the 4775 code is exclusive to the Funabashi region. However, due to number exhaustion, some adjacent areas have adopted overlay codes, but Funabashi has not yet required one.

Caller Instructions

For local callers: If you are within the 4775 area, you can dial the 7-digit number directly. If you are calling from a mobile phone, you must always include the area code (04775) even if you are in the same region, as mobile networks do not recognize local dialing.

For foreign callers: When calling from overseas, remember to replace the leading '0' with the country code +81. Ensure you have the correct exit code for your country. For example, from the UK, dial 00 81 4775 1234567.

Services and Usage

Numbers with the 4775 prefix are primarily used for residential and business fixed lines. They are also used by VoIP providers that offer geographic numbers. Emergency services (police 110, fire/ambulance 119) are reachable without an area code. For directory assistance, dial 104.
