Why does the Zip code change with General Delivery?

Overview

We are running transactions with General Delivery on line address  it's changing the zip-code and returning a incorrect tax rate.

Environment

Avalara Avatax

Resolution

  • When General Delivery is used it generalizes the address it can change the base zip code as well as add the zip-code extension '9999' for this reason General Delivery is a last resort to pass address validations with new addresses that are not in the system yet 

This is not a replacement for a street address.
