I would really, REALLY recommend you get them to change it. I moved in the same town last year and had a frigging packaged RTS'd to Japan rather than them forward the package.
It made no sense and just pissed me off. I was getting mail forwarded just fine, I tracked the package and saw it was out for delivery to my old address. Instead of them checking or whatever so to see that it was a forwarded address, the USPS guy somehow knew I was no longer living there when he got to the house, and decided to RTS the package back to Japan, rather than check if there was a forwarding address. I went to the USPS the next day and they were like, 'it's in the automated processing center, we can't stop it.' and they couldn't. It was in their processing center and even though it didn't leave the country to go back to ****ing Japan like a day or 2 later, they couldn't do anything to stop the package and grab it before it was loaded back on a plane. There's a certain point where it's all automated and you literally can't do anything.
I had to contact Nippon Yasan and have them ship the package back to me, at my expense of course.
