Send RCS Verifications With the Vonage Verify RCS Default Agent

Vonage’s Verify RCS Default Agent is a centrally managed, pre-registered RCS sender that lets eligible Verify V2 API customers in supported countries send RCS authentication messages immediately without waiting for carrier approval or completing custom agent registration. Developers enable it by omitting the `from` parameter, setting the workflow channel to RCS, and using the standard Verify API process to initiate and validate one-time passcodes with a returned request ID. Messages are sent from the verified “Vonage Verify” agent, while the customer’s brand can appear in the message body; organizations can register their own branded agent in parallel for a later transition. The service supports fallback workflows that attempt RCS first and SMS second, with Vonage handling channel selection automatically. Compared with SMS, RCS can offer rich OTP cards, copy-code controls, autofill support on compatible devices, and a carrier-verified sender identity, while pricing, general API usage limits, and billing remain the same as standard Verify RCS.
