Abstract: Methods and systems for disambiguating entries within a contacts listing database of a mobile device detect newly created contact records having a same data element (e.g., a telephone number) and alert the user. Other contact records storing the same data element may be identified. Matching contact records may be grouped and provided a group label so that when a call is received from a member of the group, the mobile device can identify the caller using the group label. Call logs can similarly be disambiguated by informing a user when a call has been made to or received from a number that matches values in data fields of more than one contact record and enabling the user to edit or augment information recorded in the call log to properly reflect the identity of the other party to the call.
