Business would like to electronically communicate with a customer but may not have the resources to actively acquire the customer's phone number. To passively acquire and link a customer's phone number to the customer's account, a unique code may be created for each customer. A proxy code for the unique code may also be created. The proxy code may be sent to the customer with an invitation to open a new account, receive a new service, or renew a service by returning the proxy code by phone call or text message. The proxy code may then be received from the customer by phone call or text message. The phone number from which the phone call or text message has been received may be authenticated. The phone number may then be linked to the unique code based on the proxy code. |
