Verification Numbers

Short-term US numbers for one-time SMS verification codes. A 15-minute window with an automatic full refund if no code arrives.


For one-time verification codes (OTP, account registration and similar).

  • Duration: 15 minutes
  • Country: US numbers
  • Use case: receive a verification code from the service you picked
  • Refund: if no code arrives within the 15-minute window, the rental is cancelled and refunded in full automatically. You can also cancel it yourself for a full refund any time before a code arrives. Once a code has been delivered, the rental can't be refunded.
  • Reuse: need another code from the same service? Reuse the number

The exception is services marked non-refundable: the dashboard warns you before you rent, and those numbers are charged whether or not a code arrives.

How It Works

  1. Rent a number for your chosen service
  2. Enter the number on the service you're verifying
  3. Wait for the code: it appears on the number's page as soon as it arrives
  4. Use the code. Release Number moves the rental to your history (optional: the slot is already free once the code arrives)
  5. Need another code? Use Reuse while the rental is still active
  6. If no code arrives within 15 minutes, the rental is cancelled and refunded automatically

If No Code Arrives

A code that doesn't arrive usually means the service declined to send to that number or session, not that the number is broken. Try a new number from a clean connection without a VPN. For strict services, a dedicated number has the best success rate.

If Telegram says the code was sent to your Telegram app instead of by SMS, the number already has a Telegram account. Cancel the rental for a refund and take a new number.

Service Not Listed?

If your service isn't in the list, the "Service Not Listed" option works as a fallback, with lower success odds. You can also request a service from the dashboard. One-time numbers and rentals aren't offered for banking, payments, lending, investing, gambling, government, identity verification or gift card services (crypto exchanges are available).
