Why is tax charging differently with just the zip code?

Overview

When calculating tax with the zip+4 and the street address it charges a different rate then when calculating with just the zip+4

Environment

Avalara Avatax

Resolution

When only the Zip+4 is present Avalara uses the most common rate found within the Zip+4's boundary when the address is included the tax rate for that location might fall outside that boundary resulting in a different tax result.
