# When to rent a number instead of buying a one-time OTP

Rent the number if you will log in again, reset a password, or add a second device. Buy an OTP only for a single code.

Rent a number when the same phone field has to keep working after the first signup. On SMS.Red an OTP dies after 20 minutes. A rental is the product you open under New rental — Unlimited or a specific app — and keep for 12 hours to a year.

## Signals you need a rental

- The app sends a new code every time you switch devices.
- You enabled SMS 2FA and you will actually use it.
- Support told you they will text a reset link to the original number.
- You already burned an OTP and the account now refuses a different prefix.

## Unlimited vs per-service

Unlimited Rental is the generic pool: one number, many senders. Per-service rentals (Telegram, WhatsApp, Amazon, Claude, and the rest of the catalog) are the right pick when that one app is the whole point of the line.
