Summary

Bird Verify confirms control of a phone number or email address by sending a code and checking the response. It supports SMS, email, WhatsApp, and channel orchestration; voice OTP is described as rolling out. An eligible fallback can send a code through another channel while retaining the same verification and expiry. Bird says codes are generated from a cryptographic random source, stored as HMAC-SHA256 hashes, and compared in constant time. Sessions have a bounded number of code checks, five by default, and sends have recipient caps and a resend cooldown. Phone numbers must use international format, and requests cannot add channels unavailable in the country configuration. WhatsApp verification uses a Bird-managed business number and authentication template, with availability restrictions in some countries. Developers can build with Node.js, Python, Go, PHP, cURL, CLI, or MCP. The free Verify plan has no separate verification fee; charges apply for channel messages sent. Bird lists API and web platforms, plus workspaces, API controls, team roles, and audit logs.
