Why Real Non-VoIP Numbers Work Better for Verification
OTP Grove delivers real non-VoIP phone numbers online for SMS verification — receive OTP codes on genuine carrier routes across 150+ countries. Built for WhatsApp, Telegram, Google, PayPal, Discord, and 500+ apps that reject VoIP numbers.
- How does OTP Grove work?
- Sign up, top up your wallet with crypto via Cryptomus, pick a service and country, and order a number. The OTP appears in your dashboard within seconds. If no SMS arrives, you are auto-refunded.
- What payment methods are accepted?
- Crypto only via Cryptomus — USDT (TRC20 / ERC20), BTC, LTC, ETH, SOL, TRX and other major coins. There are no credit cards or bank transfers.
- Are these real non-VoIP USA numbers?
- Yes — carrier-grade non-VoIP USA lines, which is why they consistently succeed on apps that reject VoIP numbers (WhatsApp, Telegram, PayPal, financial services).
- How fast is OTP delivery?
- Typically under 30 seconds. If the SMS does not arrive within the delivery window, the cost is refunded automatically — you only pay for verifications that actually succeed.
- Which countries are supported?
- 150+ countries across the USA, Europe, Asia, Africa and Latin America. The flagship product is the USA Main non-VoIP line for high-security app sign-ups.
- Is there an API for developers?
- Yes — see the REST API documentation for endpoints, auth, and language examples.
