Which term best describes the sequential order in which a form is added to a policy?

The correct term that describes the sequential order in which a form is added to a policy is "Endorsement Number." In insurance terminology, an endorsement typically refers to a change or addition to an insurance policy, and each endorsement is assigned a unique number to identify it in relation to the policy. This sequential numbering allows for easy tracking and reference of the specific modifications made to the policy over time, ensuring clarity and organization.

In contrast, the other terms do not specifically denote the order of form additions to a policy. A policy number identifies the overall insurance policy itself, a form code indicates the specific type of form used without implying any sequential order, and a tracking number is often used to monitor processes or items but is not specific to the sequencing of forms within a policy. Thus, "Endorsement Number" accurately conveys the intended concept of the sequential addition of forms.
