sending the query requesting CNAM information to a CNAM database and receiving CNAM information in response thereto; and

sending the reputation message and the CNAM information to the carrier platform in response to the query requesting CNAM information.

8. A non-transitory computer readable storage medium storing executable computer program instructions for delivering reputation information, the computer program instructions comprising instructions that when executed cause a computer processor to:

receive a query from a carrier platform requesting caller ID name (CNAM) information associated with a call from a caller number;

responsive to receipt of the query, interfacing with the carrier platform to delay the call;

determine reputation information responsive to the caller number, the reputation information indicating a likelihood that the call is a nuisance call;

generate a reputation message describing the reputation information; and

send the reputation message to the carrier platform in response to the query requesting CNAM information.

9. The computer readable medium of claim 8 , wherein the computer program instructions for receiving a query from the carrier platform requesting CNAM information comprise instructions that when executed cause the computer processor to:

intercept a query sent from the carrier platform to a CNAM database requesting CNAM information for a call placed by a calling device having the caller number;

wherein the carrier platform sends the reputation message to a called device using a caller identification (ID) service and the called device displays the reputation message.

10. The computer readable medium of claim 8 , wherein the computer program instructions for determining reputation information comprise instructions that when executed cause the computer processor to:

send the query requesting CNAM information to a CNAM database and receiving CNAM information in response thereto, the CNAM information and the caller number comprising caller identity information; and

query a reputation database using the caller identity information, the reputation database storing reputation information in association with caller identity information, and receiving the reputation information in response thereto.

11. The computer readable medium of claim 8 , wherein the computer program instructions for determining reputation information comprise instructions that when executed cause the computer processor to:

generate the reputation information responsive at least in part to a call activity history associated with the caller number.

12. The computer readable medium of claim 8 , wherein the computer program instructions for generating a reputation message comprise instructions that when executed cause the computer processor to:

represent the reputation information as a quantitative reputation score having a value indicating a likelihood that the call is a nuisance call;

associate a text label with the quantitative reputation score; and

generate the reputation message responsive to the text label.

13. The computer readable medium of claim 8 , wherein the computer program instructions for generating a reputation message comprise instructions that when executed cause the computer processor to:

determine a text label describing the reputation information;

identify a code value corresponding to the text label in a dictionary; and

form a reputation message containing the code value;

wherein the carrier platform sends the reputation message to a called device using a caller identification (ID) service, the called device detects and interprets the code value contained in the reputation message to identify the text label describing the reputation information, and the called device displays the text label.

14. The computer readable medium of claim 8 , wherein the computer program instructions for delivering reputation information further comprise instructions that when executed cause the computer processor to:

send the query requesting CNAM information to a CNAM database and receiving CNAM information in response thereto; and

send the reputation message and the CNAM information to the carrier platform in response to the query requesting CNAM information.

15. A computer system for delivering reputation information, the system comprising:

a computer processor for executing computer program instructions; and

a non-transitory computer readable storage medium storing computer program instructions executable by the processor to:
