@USPSHelp a customer left their apartment number off their address. The package (from UK to Oregon) hasn't reached the local Post Office yet. Is there any way I can add the apartment number or somehow make sure the package still gets delivered?
Well, I've just used the new Royal Mail doofer for sending to the USA. So far, so good, it calculated and added the customs charge (10% of item value) and I've got my label.
If it's accepted no problem at the Post Office later, then I'm a happy bunny.
