Can I use 5 digit zip codes with SalesTaxII?

Overview

I need to use five digit zip codes with SalesTaxII. 

Environment

SalesTaxII 

Resolution

  • The use of 5 digit zip codes is allowed, but accuracy may be noticably reduced.

  • Using Signature Code or City Name with Zip+4 are the most accurate methods when accessing tax rates in SalesTaxII.

  • Please be aware that a 5 digit zip can be shared by more than one city and/or county.

  • To improve accuracy when using 5 digit zips, you should supply the city name along with the zip code. Even with city name misspellings, accuracy will be greatly improved.
