Japan Calling Code FAQ
- What is the country calling code for Japan?
- +81. From abroad, dial your network’s exit code (or +), then 81, then the Japanese number with the leading 0 removed. From Japan outbound, the standard exit prefix is often 010 when digits are required instead of +.
- Is it +81 or 81?
- Same code. +81 is the portable form for contacts and mobiles; 81 is what follows an origin exit prefix (for example 011 81… from the US, or 010 81… when dialing out from Japan with digits).
- Do I drop the leading 0?
- Yes for Japanese numbers after +81. Domestic 03… → +81 3…; domestic 090… → +81 90…. Do not store +81 (0)… or +81 03….
- How do I dial a Japan mobile from abroad?
- From 090 XXXX XXXX, drop the first 0, then dial or save +81 90 XXXX XXXX (or exit code + 81 90 XXXX XXXX).
- Is Japan’s exit code 00?
- Usually not. Japan’s documented standard exit is 010; carrier-selection alternatives (for example 001, 0033) also appear. Do not assume the Europe-style 00 exit when dialing from Japan.
How to Dial Japan
Saving the number in contacts
Start with +81, then use the reviewed national significant number. Remove the first domestic 0 before adding +81.
Calling from abroad
On a mobile, use the + form. If a network requires digits instead, replace + with that origin network's international prefix. Japan's own standard exit prefix for outbound calls is 010; documented alternatives include 001, 0033, 0041, 0061.

Exceptions and Routing Notes
Common Japan Formatting Mistakes
- Keeping the leading 0 after +81.
- Assuming 00 is the normal exit code from Japan.
- Treating a carrier-selection prefix as part of the destination number.
Number Portability and Carrier Data
Mobile number portability means a prefix may not identify the current carrier. Treat carrier data as a timestamped lookup result, not a permanent property of the number.
