A group number on an Aetna insurance card identifies the policyholder’s employer or organization through which the health insurance plan was obtained. For instance, if an employee receives health insurance through their workplace, the group number may be found on their Aetna card.
Possessing the group number is crucial because it allows individuals to make changes to their health coverage, access plan documents, and connect with customer service. It was initially introduced to streamline insurance management for employers and employees.
