How it works

Pick your Claude number type.

If you’re testing a signup, you can try a free inbox. If you want a better success rate or may need access again later, choose Activation or Rental. Those options are usually more stable for OTP delivery.

Choose the country + number.

Select the country you need, get a number, and copy it carefully. Paste it in clean format: +CountryCodeNumber or digits-only if the Claude form does not accept the plus sign.

Request the OTP on Claude

Enter the number on Claude, request the verification code, and avoid repeated resends. Send the code once, wait a bit, then refresh or resend only once if needed.

Receive the SMS on PVAPins

When the OTP arrives in your PVAPins inbox, copy it and enter it into Claude right away. Verification codes can expire quickly, so it is best to use them as soon as they appear.

If it fails, switch smartly.

If no code arrives or the verification fails, do not keep retrying. Switch to another number or use a better route, such as Activation or Rental. In most cases, that is the fastest way to fix Claude SMS verification problems.

Japan number format (quick copy)

Country code: +81
International prefix (dialing out locally): 010
Trunk prefix (local): 0 (drop it when using +81)
Mobile pattern (common for OTP): mobiles typically start with 070 / 080 / 090 locally
Mobile length used in forms: usually 10 digits after +81 (because the leading 0 is removed)

Common pattern (example):

Mobile: 090-1234-5678 → International: +81 90 1234 5678 (drop the leading 0)

Quick tip: If the form rejects spaces/dashes, paste it as +819012345678 (digits only).
