Frequently Asked Questions — Japan Temporary Numbers

Can I use a Japanese virtual number for LINE?

Yes, Japanese +81 numbers work for LINE registration. Select Japan (+81) as your country in LINE, enter the mobile number (without +81), and wait for the OTP. LINE typically sends the code within 30–60 seconds. If one number fails, try another freshly added number from our list.

What is Japan's phone country code?

Japan's international dialling code is +81. To call a Japanese mobile from overseas, dial +81 followed by the mobile number without the leading 0. Japanese mobiles use 070, 080, or 090 in local format, which becomes +81 70, +81 80, or +81 90 internationally.

Do Japanese numbers work for Mercari?

Yes, Mercari Japan accepts phone verification via +81 numbers. Enter the Japanese number on the Mercari Japan app or website during registration. The OTP will appear in the inbox on this page. Note: Mercari US and Mercari Japan are separate apps and may have different verification requirements.

Why are Japanese numbers sometimes slow to deliver OTP?

Japanese SMS routing can sometimes take 30–120 seconds longer than Western carriers due to Japan's highly regulated telecom infrastructure. NTT Docomo numbers typically deliver fastest. If you're waiting over 3 minutes, try a different number — the previous number may have been flagged by the platform.

Are these Japanese numbers free forever?

Yes, completely free with no time limits or usage caps. However, these are public shared numbers — anyone can see the incoming messages for each number listed. Do not use them for banking, PayPay wallet funding, or other sensitive financial Japanese services.
