Abstract: Systems and methods for managing dynamic number insertion pools are disclosed. Tracking re-use of a phone number in swaps, associated with a client pool, over a first period of time, may be performed. Based on the re-use, generating a risky swap value for the client pool may be done. In response to the risky swap value reaching a threshold, an assignment snapshot may be generated. A recommended value for a pool size may be generated based on the assignment snapshot.

Abstract: A system for dynamic number insertion may include at least one application operable on at least one client device and at least one public facing API operable on at least one server, the at least one API configured receiving a request for a phone number swap comprising attribution information from the at least one client device, providing a phone number based on the attribution information to the at least one client device, receiving notification of a phone call made to the phone number, and attributing the phone call based on the attribution information. The at least one application can be interfaced to the at least one public facing API.
