In order for a newborn to be added as a dependent, you must complete an application and provide your human resources department with a birth certificate or a copy of the birth letter within 30 days of the child’s birth date. The birth letter will suffice as proof of parentage only if it contains the relationship of the child and the employee. If the birth certificate or birth letter is not received, enrollment may not take place until the next annual enrollment period or an OGB Plan Recognized Qualified Life Event.
