Free vs Activation vs Rental (what to choose)

Free (public inbox)Good for quick tests. Higher block risk because numbers are reused.
Activation (one-time)Better OTP success for verification flows. Use when success matters.
RentalBest for re‑logins, password resets, and recovery. Keep access longer.
Simple ruleFree → Activation when blocked → Rental when you need continuity.

How it works

  • Choose your number type
    Free inbox = quick tests. Activation or Rental = typically better delivery and fewer rejections.

  • Pick country + copy the number
    Select the country you need, grab a number, and copy it exactly.

  • Request the OTP on Anthropic
    Enter the number on the Anthropic verification screen and tap Send code (avoid rapid retries).

  • Check PVAPins inbox
    Refresh once or twice, copy the OTP as soon as it arrives, and enter it immediately (codes expire fast).

  • If it fails, switch smart
    Don’t spam resend. Switch number/route, wait a bit, then try once again.

  • Japan number format (quick copy)

    Why Use a Virtual Number for Anthropic in Japan?

    You stay in control. You decide when to activate, which route to use, and whether you’ll keep the same line for future checks. That flexibility fits one-time signups, two-factor authentication (2FA), and account recovery without tying everything to your personal SIM.

    • Keep your personal number private and separate work/life cleanly.

    • Cut spam and promotional texts hitting your real phone.

    • Switch country routes quickly if an OTP slows or fails.

    • Choose Temporary for quick activation or Rental for re-logins.

    • Works with most mainstream verification flows, with no complex setup.

    • Local note: In Japan, delivery can vary by carrier/peak hours; route switching usually fixes delays.

    Example: If an OTP stalls during evening peak, switching to an alternate Japan route (or a nearby country) often resolves it within moments.


    Steps to Get Anthropic Verified in Japan Without a SIM Card

    Let’s break it down into five quick moves, and you’re done.

    1. Open PVAPins → choose Japan and select Anthropic.

    2. Pick Temporary (one-time) or Rental (long-term).

    3. Click "Get Number" and copy your assigned line number.

    4. Please enter it in Anthropic, then request the verification code.

    5. Watch your PVAPins inbox; paste the OTP into Anthropic to verify.

    Closing tip: If you’ll re-login often, switch to a rental so your line stays the same.

    Cost & Rental Plans for Japan Users

    Temporary: Perfect for one-time verifications or quick tests. Pay once, receive the OTP, and you’re done, ideal for new Anthropic sign-ups.

    Rental: Best for continuity, frequent re-logins, password resets, or device changes. Keeping the same line reduces lockouts and repeated checks.

    With PVAPins, pricing is transparent. You’ll see the rate before you start, and there are no hidden fees. For many users in Japan, a short rental saves time (and frustration) by preventing repeat verifications during busy weeks.
