Step by step
How to verify Coinbase with a Japan number
One Coinbase code on a +81 number costs $2.74 — the 32nd cheapest of 32 countries in Asia. Full Coinbase walkthrough and troubleshooting: Coinbase verification guide.
Get your Japan number
Sign up with an email, top up with USDT or USDC and pick Japan: a plan to keep the +81 number, or a single-use Coinbase OTP number ($2.74).
Open Coinbase
Go to the phone step during sign-up or Settings → Security.
Enter the +81 number
Select Japan (+81) in Coinbase's country picker, then paste the digits your dashboard shows after +81 into Coinbase.
Enter the Coinbase code
Coinbase sends a numeric SMS code by SMS. SMS codes appear in your PhoneBorn dashboard next to the +81 number; type the code into Coinbase to finish.
Tips for Japan numbers
- After +81, Japan mobile numbers begin with 70, 80, 90 — a quick check that you pasted the whole number.
- Only need one code and the country doesn't matter? Malaysia costs $0.26 for Coinbase, against $2.74 here.
- Coinbase requires identity verification; the phone number does not replace it.
Why use a Japan number for Coinbase?
Day-to-day life in Japan runs on LINE, X and Instagram, yet Coinbase remains the app for a stable 2FA number for a crypto account. A +81 number keeps that account tied to the country without using your personal SIM.
LINE for Japanese contacts: LINE is the default messenger in Japan, and a Japanese number makes it easier to connect with friends, landlords and small businesses there.
Coinbase sends sign-in and recovery codes to the number on file.
