Global OTP service for fast, secure user verification

OTP and Verification SMS

OTP and Verification SMS

are a specialized type of transactional SMS used to securely verify a user’s identity through a one-time, time-limited code. These messages deliver an otp code or sms code directly to a user’s mobile phone to confirm actions such as account login, registration, password reset, or sensitive transactions.
Unlike promotional messaging, OTP SMS and Verification SMS are generated automatically in real time, expire quickly, and are designed solely for security and authentication purposes. Their primary objective is fast, reliable delivery with minimal latency, ensuring the otp service works even during peak traffic and across international networks. Thanks to universal mobile phone support and direct operator routing, OTP and Verification SMS remain one of the most widely adopted and trusted methods of user verification worldwide.

Robust REST API, SDKs, and documentation plus help with local compliance and sender-ID registration make deployment rapid and safe.

Easy API integration and compliance support

If a primary route fails, Mamonty automatically switches to tested fallbacks — ensuring OTPs arrive even during carrier disruptions.

Automatic fallback & routing redundancy

We separate transactional (Verification SMS) and marketing traffic so your otp service avoids spam filters and maintains consistent performance.

Transactional traffic isolation to prevent filtering

OTP timeouts cost conversions — our network is optimized to deliver OTP SMS in seconds, keeping authentication flows fast and frictionless.

Ultra-low latency for instant user verification

Mamonty routes OTP traffic through prioritized, operator-grade channels to maximize delivery rates for otp code and sms code across regions.

High global deliverability via premium A2P routes
