Abstract: A system and methods for enabling access to one or more accounts associated with a Mobile Directory Number (MDN), wherein transactional tasks may be enacted, are disclosed. Such a system includes a server coupled to receive an input transaction request from a user through a point-of-entry device and coupled to a database that corresponds the MDN to the logical address of a user account. The server includes a processor for accessing the database to identify the logical address of the MDN-associated account. A method for using the system is also disclosed in which a user enacts a transaction with an account associated with an MDN. The method includes obtaining the MDN and transaction request from a point of entry device, identifying the account using a database that corresponds MDN with account logical address, and enacting the requested transaction on the identified account using access information obtained from the database.
