Question 1

What is RealNonVoipUSNumber?

Accepted Answer

RealNonVoipUSNumber provides real temporary phone numbers for OTP and SMS verification. You can verify accounts on apps like Telegram, WhatsApp, Google, and thousands more without using your personal SIM. You only pay when a code is successfully delivered.

Question 2

How does it work?

Accepted Answer

Create an account, top up your wallet, then choose a service and country from the dashboard. We assign a temporary number, you use it on the target app, and the OTP appears in your dashboard within seconds. Developers can automate the same flow through our REST API.

Question 3

Which countries are supported?

Accepted Answer

We support 200+ countries through global number routes, plus dedicated USA non-VoIP lines (USA-1 and USA-2). Availability varies by service — check the Get Number pages in your dashboard or call GET /api/v1/services/ for live inventory.

Question 4

How long does it take to receive an OTP?

Accepted Answer

Most codes arrive within a few seconds to a couple of minutes. Delivery time depends on the target platform and carrier route. Your dashboard updates in real time as soon as the SMS is received.

Question 5

What happens if I don't receive an SMS?

Accepted Answer

If no SMS arrives before the order expires, it is automatically marked as timed out and the full order amount is refunded to your wallet. You can also cancel eligible pending orders manually. See our Refund Policy for details.

Question 6

Can I cancel an order?

Accepted Answer

Yes. Pending orders can be cancelled from your dashboard after the cancel window opens (6 minutes after the order is placed). Cancelled orders are refunded to your wallet automatically.

Question 7

What is the timeout period?

Accepted Answer

Each order is active for 20 minutes. If no OTP is received within that window, the order times out and your balance is refunded automatically.

Question 8

How do I add funds to my wallet?

Accepted Answer

Go to Dashboard → Wallet, enter an amount, and complete payment through our secure crypto checkout. Funds are credited to your balance once the payment is confirmed on-chain.

Question 9

What payment methods are accepted?

Accepted Answer

We accept cryptocurrency payments — including USDT (TRC20/ERC20), BTC, ETH, LTC, SOL, TRX, and other major coins.

Question 10

Do I get a refund if order times out?

Accepted Answer

Yes. Timed-out orders are refunded automatically to your wallet. No support ticket is required. Completed orders (where an OTP was received) are not refundable.

Question 11

What is the minimum deposit?

Accepted Answer

The minimum wallet deposit is $1. There is no subscription fee — you only spend balance when you place orders.

Question 12

How do I get an API key?

Accepted Answer

Log in and open Dashboard → API Key. Your unique key is shown there and can be regenerated at any time. Use it as Authorization: Bearer YOUR_API_KEY on API requests. Full reference is on the API Docs page.

Question 13

What is the rate limit?

Accepted Answer

API keys are limited to 60 requests per second with burst headroom for bulk jobs. If you need higher throughput for enterprise use, contact us through the Help Center or Contact page.

Question 14

Is there an SDK available?

Accepted Answer

We provide copy-paste examples in cURL and Node.js on the API Docs page. Official typed SDKs are on our roadmap — the REST API is stable and can be integrated from any language.
