Number Recycling
API Description
The “Number Recycling” API allows businesses to verify whether a phone number has changed ownership since a given date. This is essential for security-sensitive applications like authentication and customer communication, where ensuring that a phone number still belongs to the intended user is critical.
The API works by:
- Accepting a phone number and a reference date as input.
- Checking whether the number has been reassigned since that date.
- Returning a response indicating whether the number is still associated with the original user.
This helps businesses prevent fraud, ensure secure authentication, and maintain accurate customer records.
