Getting Started with SIM Swap API

The SIM Swap API is a beta feature that allows developers to determine if the SIM card linked to a phone number has recently changed, enabling an additional layer of security in environments where having an uncompromised phone number is crucial. The API includes two endpoints: one to check if a SIM swap occurred during a specified time period and another to retrieve the date when the last swap happened. To use the API, developers need to authenticate themselves using a JWT token and obtain an access token, which can then be used to make API calls. The SIM Swap API belongs to Vonage Network APIs, a collection of APIs that expose network capabilities of mobile carriers. Integrating the SIM Swap API can complement various scenarios, including adding a risk factor or fraud score to individuals, strengthening traditional 2FA methods, and monitoring fraudulent activity on customers' phone numbers.
