The Verify API allows you to send OTPs in over 220 countries and territories using Plivo’s global SMS and voice infrastructure. In some countries, pre-registration of custom Sender IDs is necessary. While Plivo provides default Sender IDs in these regions, we strongly recommend that you register your own Sender ID to ensure reliability, low latency, and an enhanced customer experience.
Verify will automatically select the registered Sender ID for the destination country. Please note that different Sender IDs cannot be used for the same country. For further details on countries with pre-registration, refer here.
