System and method for mobile number verification
A mobile phone number that is been provided by a customer during enrollment is verified for use. SS7 protocol data associated with the mobile phone number is collected and evaluated, and if the condition of the subscriber account associated with the phone number has changed or is inconsistent with the circumstances surrounding the enrollment of the phone number, the phone number is designated as one that is not to be called.
1. A method for verifying that a phone number, after authorized by a customer for use in contacting the customer, subsequently continues to be authorized for use, comprising:
maintaining, at a customer data management system and on behalf of an entity desiring to contact a customer, a phone number specified by the customer as authorized for use in contacting that customer;
when the customer is to be contacted by the entity, sending, by a status verification system, a request for status data relating to the specified phone number, the status data collected from out-of-band protocol data generated when communications are made using the specified phone number and stored in a mobile call database, the status data collected from out-of-band protocol data including a Mobile ID Created Date reflecting a date that a mobile account associated with the specified number has been set up;
accessing, by the status verification system, a ported number database having porting data representing a porting date on which the customer having the specified number has changed mobile carriers;
evaluating, at the status verification system, the status data stored in the mobile call database and the porting data in the ported number database for an eligible condition for the specified phone number, the eligible condition indicative that the specified number associated with the customer continues to be authorized for receiving communications and has not been assigned to a person that has not consented to receiving the communications, where communications to such a person is prohibited, the evaluating of the status data including: (1) determining that there is the eligible condition and that the specified phone number is authorized when the Mobile ID Created Date is about the same time as the porting date and (2) determining that the specified phone number is no longer authorized when the Mobile ID Created Date is not about the same time as the porting date.
2. The method of claim 1 , wherein the out-of-band protocol data comprises SS7 protocol data.
3. The method of claim 1 , wherein the specified phone number comprises a Mobile Subscriber Integrated Services Digital Network Number (MSISDN).
4. The method of claim 1 , wherein the specified phone number is dialed using an auto dialer to make a voice phone call to the customer when it is determined that the specified phone number may be used for contacting the customer.
5. The method of claim 1 , wherein a text message is sent to a mobile device identified by the specified phone number, when it is determined that the specified phone number may be used for contacting the customer.
6. The method of claim 1 , further comprising:
determining that the specified phone number is not a mobile phone number; and
in response to determining that specified phone number is not a mobile phone number, determining that the specified number continues to be authorized for use in contacting the customer.
7. The method of claim 1 , wherein the status data collected from out-of-band protocol data is generated when communications are made using the specified phone number within a public switched telephone network (PSTN).
8. The method of claim 7 , wherein the status data is collected within the PSTN by a Service Control Point (SCP), and is thereby based on the most recent calls made within the PSTN.
9. The method of claim 7 , wherein the status data is collected on-the-fly at multiple databases associated with multiple Service Control Points (SCPs) within the PSTN.
10. The method of claim 1 , wherein the specified phone number is removed from data maintained at the customer data management system when it is determined that there is not the eligible condition determined for the specified phone number.
11. A system for verifying that a phone number, after authorized by a customer for use in contacting the customer, subsequently continues to be authorized for use, the system comprising:
a customer data management system for maintaining, on behalf of an entity desiring to contact a customer, a phone number specified by the customer as authorized for use in contacting that customer;
a mobile call database that stores status data, the status data collected from out-of-band protocol data generated when communications are made using the specified phone number, the status data including a Mobile ID Created Date reflecting a date that a mobile account associated with the specified number has been set up;
a ported number database that stores porting data representing a porting date on which the customer having the specified number has changed mobile carriers; and
a status verification system, the status verification system:
accessing the mobile call database for status data relating to the specified phone number, when the customer is to be contacted by the entity;
accessing the ported number database for porting data associated with the specified number; and
evaluating the status data stored in the mobile call database and the porting data stored in the ported number database for an eligible condition for the specified phone number, the eligible condition indicative that the specified number associated with the customer continues to be authorized for receiving communications and has not been assigned to a person that has not consented to receiving the communications, where communications to such a person is prohibited, the evaluating of the status data including: (1) determining that there is the eligible condition and that the specified phone number is authorized when the Mobile ID Created Date is about the same time as the porting date and (2) determining that the specified phone number is no longer authorized when the Mobile ID Created Date is not about the same time as the porting date.
12. The system of claim 11 , wherein the out-of-band protocol data comprises SS7 protocol data.
13. The system of claim 11 , wherein the specified phone number comprises a Mobile Subscriber Integrated Services Digital Network Number (MSISDN).
14. The system of claim 11 , wherein the specified phone number is dialed using an auto dialer to make a voice phone call to the customer when it is determined that the specified phone number may be used for contacting the customer.
15. The system of claim 11 , wherein a text message is sent to a mobile device identified by the specified phone number, when it is determined that the specified phone number may be used for contacting the customer.
16. The system of claim 11 , further comprising:
determining that the specified phone number is not a mobile phone number; and
in response to determining that specified phone number is not a mobile phone number, determining that the specified number continues to be authorized for use in contacting the customer.
17. The system of claim 11 , wherein the status data collected from out-of-band protocol data is generated when communications are made using the specified phone number within a public switched telephone network (PSTN).
18. The system of claim 17 , wherein the status data is collected within the PSTN by a Service Control Point (SCP), and is thereby based on the most recent calls made within the PSTN.
19. The system of claim 17 , wherein the status data is collected on-the-fly at multiple databases associated with multiple Service Control Points (SCPs) within the PSTN.
20. The system of claim 11 , wherein the specified phone number is removed from data maintained at the customer data management system when it is determined that there is not the eligible condition determined for the specified phone number.
