Japanese phone number for SMS verification 🇯🇵

Japan numbers, in detail

• Which services work with Japan numbers?

  The list above is the full catalogue for Japan, and each row carries its own state: measured by us, reported by a named supplier, or no data at all.

  Every success rate on this site is either measured from our own orders — shown with the sample size and the time window — or a named supplier's figure we pass through and label as theirs. Where we have neither, we say so. We never show a number we can't source.

• How do I get a Japanese phone number for verification?

  Choose the service you need from the list above and pay for that one code. A temporary Japanese phone number and a Japanese phone number for verification are the same thing here: one private line, rented for a single code.

  No signup needed to see any price. No hidden fees. When ordering opens: if a code doesn't arrive, you don't pay.

• Do I have to be in Japan?

  No. The SMS is delivered to the number itself, so the country of the number is what matters, not where you happen to be.

• What does a Japan number look like?

  Japan numbers start with the country code +81. National mobile numbers carry 10 digits after the country code.

  You see the full number the moment the rental starts — we never show it before, because a number nobody has rented yet is not yours to use.

• What if the code does not arrive?

  If a code doesn't arrive, you don't pay. We auto-refund your wallet within 5 minutes when a number fails to receive a valid code. No form, no waiting. Refunds go to your readynum balance instantly and never expire. Prefer a card refund? Ask support and we'll send it back the way you paid within 5 business days.

• Are free Japan numbers good enough?

  Free numbers are public — anyone can read the messages. Great for throwaway signups.

  Need it to actually arrive? Free numbers are public and often blocked. Get a private number.

• Is a number ever shown as available when it is not?

  Stock is a yes or a no, never a count — and when ordering opens, anything shown in stock is buyable.

  Availability is binary on this site. A route is either buyable at this moment or it is marked out of stock — we never publish how many lines sit behind it, because that figure is not verifiable for anyone reading it.
