OTTO verification numbers

Median delivery is under 9 seconds from the moment the service sends the SMS. The number itself is issued instantly. If nothing arrives inside the 20-minute activation window, the order is cancelled automatically and refunded in full.

That means the operator range is flagged for that specific service. Cancel the activation — you are refunded — and buy again: you will get a different range. If a whole country keeps failing for a service, its success-rate badge on the pricing page will already show it; pick a country above 85 %.

Not with a one-time activation: the number returns to the pool afterwards. If you need the same number for repeat logins, use a rental — from four hours to twelve months, with unlimited SMS from the chosen service.

Enable multi-SMS before buying, and the activation stays open for additional messages from the same service until the window closes. Each extra message is billed at 30 % of the base price. Rentals include unlimited messages.

Automatically and in full whenever an activation ends without a code: no SMS in the window, the number turns out to be blocked by the service, or you cancel before any message arrives. The credit is on your balance within seconds. Balance itself is not withdrawable back to crypto except for referral earnings above €50 — see the refund policy.

Yes, on every account, at no extra cost, from the first euro of balance. Create a key in the dashboard, send it as a bearer token, and you have the same capabilities the web interface uses.
