Wrong Addresses - Sad Situation

If a customer puts a wrong zip code sometimes the software we have will catch it. We then call the customer, unless its very obvious. Obvious being the bill to zip code was put in the ship to zip code with different cities and states for each.

Another time the mailing software asked if a street was West or East, so we called the customer and they replied it did not matter.

Another time the address was so new that that the mailing software did not include it.

If the software we use does not catch it, we don't find out till the package is returned to us. The Postal Service does not send any notification of a problem with an order till its returned to us.
