Addresses with Apartment or Suite #'s

Good Evening,

We are having a continuous problem with Address Validation in Shiprush web for addresses that have an apartment or suite number. We run our address validation on strict however even when we reduce it to basic we still are unable to confirm the addresses. We have contacted the many customers and they have verified the address. When this occurs we have to pull up Fedex Ship Manager and ship with in that program.

What can we do to fix this?

Sincerely,
