Inside Japan, numbers are dialled with a leading 0; leave it out after +81.
Japanese mobile numbers start with 070, 080 or 090 inside Japan. From abroad, drop the leading 0 and add +81, so 090 becomes +81 90, followed by eight more digits.
Didn't get the code?
Free numbers are shared, so a code can fail to arrive for reasons nobody here controls:
- Someone else may already have used the number to sign up to the same service, so it refuses the number.
- Many apps can block VoIP numbers and numbers that many people have used, and every public number here is used by many people.
- Some services only send codes to certain countries.
VoIP and non-VoIP numbers
A VoIP number runs over the internet. It is cheap and quick to issue, and many apps reject it for verification. A non-VoIP number belongs to a mobile carrier and is tied to a SIM card. Apps accept it more often, but none of them promise to.
A private number is used by you alone, so nobody else can read your codes or reuse the number.
You'll continue on app.privasto.com to choose a number and pay. The app shows whether a number is a virtual (VoIP) line before you buy.
