Verify API: Identity Verification

A phone verification API is a tool that allows developers to confirm user identities by sending one-time passwords (OTPs) to phone numbers.

It boosts success rates by reaching users on their preferred channels. A multi-channel API also helps reduce drop-offs and adapt to different user environments.

SMS OTP is the most widely used option, but other channels like email, WhatsApp, and voice calls can work just as well depending on your users’ preferences, location, and device access. It's best to offer multiple options so users can choose what works for them.

Dexatel supports global phone number verification API coverage in over 190 countries. It works across all major regions, helping you authenticate users no matter where they are.

It depends on your usage and channel preferences. Dexatel offers flexible, usage-based pricing. If you're sending occasional verifications, the standard pay-as-you-go plan is usually enough. For larger volumes or specific regional needs, you can request custom pricing that better fits your scale and preferred channels like voice or SMS OTP.
