A multi-modal address book for a customer associated with at least one account in an electronic communications environment is provided. The multi-modal address book is associated with a customized profile of the customer and has multiple entries. Each entry of the multi-modal address book is associated with a communications partner and includes at least one address. Information of a centrally stored copy of the address book is automatically synchronized with a copy of the address book provided at a remote communications device when information of an entry is altered at either the centrally stored address book or the copy of the address book. An indicator can be stored in association with at least one of the entries of the address book. The indicator indicates that an address book of a communications partner corresponding to an entry is to be automatically updated when the profile of the customer is altered. The updating occurs without regard to the modality used to communicate with the stored address.
