MNP stands for Mobile Number Portability. It is the customer's right to switch operators while keeping their original phone number. It is important because the MNP API allows you to know which actual operator the number currently belongs to, which is vital for reliably directing your communications and preventing fraud via mobile telephony.
The API provides the current operator where the number is active, and in many cases, can also indicate the original operator.
MNP API information is obtained from portability databases, which are constantly updated with operator changes. The Plusmo API ensures that you receive information in real-time or with the lowest possible latency.
Although the main goal is to identify the operator, the API can often indicate the number's status (if it is a real number and if it is active on a network), which is a basic validation of validity and operability, complementing your onboarding and data cleansing processes.
