Step by step
How to verify WhatsApp with a Japan number
One WhatsApp code on a +81 number costs $1.90 — the 32nd cheapest of 32 countries in Asia. Full WhatsApp walkthrough and troubleshooting: WhatsApp 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 WhatsApp OTP number ($1.90).
Open WhatsApp
Go to the first screen after installing WhatsApp (or WhatsApp Business) — “Enter your phone number”.
Enter the +81 number
Select Japan (+81) in WhatsApp's country picker, then paste the digits your dashboard shows after +81 into WhatsApp.
Enter the WhatsApp code
WhatsApp sends a 6-digit code by SMS, or a voice call if the SMS does not arrive. SMS codes appear in your PhoneBorn dashboard next to the +81 number; type the code into WhatsApp 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 $0.18 for WhatsApp, against $1.90 here.
- Turn on two-step verification (Settings → Account) so nobody can re-register your number.
Why use a Japan number for WhatsApp?
Day-to-day life in Japan runs on LINE, X and Instagram, yet WhatsApp remains the app for reaching customers, family and a business audience in the country. A +81 number keeps that account tied to the country without using your personal SIM.
Selling and buying on Mercari: Resellers and collectors trading anime goods, cameras or vintage fashion on Japanese marketplaces use a +81 number for account verification.
WhatsApp re-verifies whenever you move to a new phone, reinstall or restore a backup, so a number you keep is the only way to stay in control of the account.

The cheapest option nearby is Malaysia (+60) at $0.18. Among the 113 apps we sell Japan codes for, WhatsApp is the 89th cheapest.
Can I use a Japan number for WhatsApp?
Yes. WhatsApp expects a real mobile number, and every Japan (+81) number we sell is one. If WhatsApp turns yours down, the 7-day replacement guarantee swaps it for another Japan number; a single WhatsApp code that never arrives is refunded to your PhoneBorn balance.
OTP number or phone-number plan for WhatsApp in Japan?
One WhatsApp code on a Japan number costs $1.90 and covers a single WhatsApp check; a plan (from $1.80/month on the 12-month plan) keeps the +81 number and receives WhatsApp codes as often as WhatsApp asks. WhatsApp sends its 6-digit code by SMS, or a voice call if the SMS does not arrive: a plan receives SMS and incoming calls, an OTP number the SMS code only.
