In an embodiment, an authentication device receives the call request and associated calling party information that includes a calling party number. The authentication device retrieves parameters associated with the calling party number, where a retrieved parameter is a number of accounts linked to the calling party number. The authentication device determines whether the number of accounts is between one and a threshold value, inclusive, and verifies that the call request originates from a location or a device associated with the calling party number. Based on the verifying and determining, the authentication device generates an authentication result that indicates whether the calling party number is authenticated. Then, the authentication device sends the authentication result to a call processing device that processes the call request from the caller according to the authentication result. ## Claims ### Claim 1 A method, comprising: receiving, by an authentication device, a call request and associated calling party information that includes a calling party number, wherein the call request is initiated by a caller; retrieving, by the authentication device, one or more parameters associated with the calling party number, the one or more parameters comprising a number of accounts linked to the calling party number;
