Japan Phone Number Format

Country code +81 — Complete guide to Japan phone number formats, mobile and landline structures, and area codes.

Number Format Overview

Phone numbers in Japan use the international country code +81. When dialing from outside Japan, you must include this country code before the local number.

International Format

+81 [area code] [local number]

From the United States

011 81 [area code] [local number]

When dialing a number within Japan, local dialing rules apply. You may need to include a trunk prefix (often 0) before the area code for domestic calls, but you should omit this prefix when dialing internationally.

Dialing Tips

Remove the leading zero: When dialing internationally, drop the trunk prefix (usually 0) that is used for domestic calls in Japan.
Use the + notation: From a US mobile phone, use +81 instead of 011 81.
Verify the number length: Make sure you have the correct number of digits. If your call does not connect, check whether you need to add or remove an area code digit.
Save contacts in international format: Always store phone numbers with the full +81 prefix so they work from any country.
