US Patent 11356477 Verifying incoming communications

Disclosed are systems, methods, and non-transitory computer-readable media for verifying an incoming communication. A recipient client device receives an incoming communication including an identifier identifying a second client device as having initiated the incoming communication. A verification service installed on the recipient client device queries a call placement service directory based on the first identifier. The call placement service directory maintains a listing of identifiers for client devices and corresponding communication providers that manage the identifiers. The call placement service directory returns information identifying the communication provider that manages the identifier. In turn, the verification service transmitting a request to the communication provider to confirm whether the second client device initiated the incoming communication. The verification service processes the incoming communication based on the response from the communication provider indicating whether the second client device initiated the incoming communication.
