Apparatuses, computer-implemented methods, and computer program products for improved user account identification for shared account linking

Abstract

Embodiments are provided that improve identification of user accounts for linking with a shared account, specifically user accounts suggested for linking with a consumer sharing account using specific electronically managed data to dynamically allocate data to the consumer sharing account. Some example embodiments detect electronic marketing information corresponding to user identifier(s) via a plurality of data sources, identify a consumer sharing account associated with a first user identifier, determine suggested user identifier(s) not associated with the consumer sharing account based on a portion of the electronic marketing information associated with the suggested user identifier(s), detect a transaction associated with the first user identifier, allocate at least a first portion of a dynamically-allocable transaction metric, and in response to detecting the transaction, cause generation at a first user device of a graphical user interface display that upon interaction causes sending of a consumer sharing account notification.
