What a Japanese phone number looks like: example and format

Example of a Japanese phone number: +81 90-XXXX-XXXX — Japanese mobile numbers start with 070, 080 or 090 (the zero is dropped when dialing internationally: +81 90…), Tokyo landlines start with +81 3. A random Japanese number from a generator will not receive SMS: it is a non-existent combination. A virtual Japan number from DIDVN is a real +81 number assigned to you, receiving SMS and calls.

Frequently Asked Questions About the Japan Number

What's the code for Japanese numbers and which carriers are available?

Japanese numbers start with +81. The main carriers are NTT Docomo, SoftBank, and au (KDDI), and for services tied to a specific provider you can specify the one you need when ordering.

Will the number work for registering on Mercari?

Yes, Mercari — Japan's largest resale marketplace — requires verification with a Japanese number when registering, and a virtual number works for this just like a regular one.

Can I use the number for verification at banks like MUFG or SMBC?

Yes, Japanese banks send an SMS code to any active +81 number when logging into online banking or confirming a transaction — the bank doesn't distinguish the number's origin.

Why is a local Japanese number so important for many Japanese services?

Japan has a widespread practice of tightly linking registration to a local phone number — banks, delivery, government services, and marketplaces often simply don't accept foreign numbers, so a Japanese number is critical for full access to local services.

If partners in Tokyo call this number, is it a local call for them?

Yes, for someone calling from Japan it's a regular domestic call to a +81 number at the local rate, not an international one.

Can I register LINE on a Japanese number?

Yes, the number supports registering on LINE — the dominant messenger in Japan, without which it's difficult to handle both personal and business communication in the country.

Is the number suitable for business with Japanese partners?

Yes — Japan is one of the world's largest economies, and a local number is important for business contacts, especially given local business communication culture.

Does the number support calls, SMS, or both?

Both options are available — you can choose an SMS-only number for one-time codes or a full number with voice calling, depending on the task.

How quickly does a Japanese number activate after payment?

Disposable numbers and mobile numbers with an XXXX mask are activated immediately after purchase. Activating a rented or permanent number takes 1–5 business days, most often 1–2 days.

Yes, using a virtual number doesn't require Japanese citizenship or residency — it's a standard carrier service.
