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

  • Pick your Firebase number type.

    If you’re only testing a signup, a free inbox can be enough. If you want better delivery success or may need to log in again later, choose an Activation or Rental number, since those options are usually more reliable and blocked less often.

    Choose the country and number.

    Select the country you need, get a number, and copy it carefully. When entering it on Firebase, use a clean format like +1XXXXXXXXXX or digits only if the form does not accept symbols.

    Request the OTP on Firebase

    Paste the number into the Firebase verification form and tap Send code. Do not spam the resend button. Send the request once, wait a bit, and refresh or resend only once if needed.

    Receive the SMS on PVAPins

    Once Firebase sends the code, the OTP will appear in your PVAPins inbox. Copy the code and enter it back into Firebase as soon as possible, because verification codes can expire quickly.

    If verification fails, switch smartly.

    If you see messages like “Try again later” or no OTP arrives, avoid resending the OTP repeatedly. The better fix is usually to switch to a new number or upgrade to a stronger route like Activation or Rental.

    • Spain number format (quick copy)

    Country code: +34

    Typical format: +34 XXXXXXXXX (9 digits)

    Tip: Don’t add a leading 0 or extra spaces. If the platform has both Spain and Spanish territories/regions, pick Spain and enter the full 9 digits.
