We get that all the time I live at 11613 S. Creek & the street over from me is 11613 N. Creek, we're always swapping mail lol
And we found out that if our address of "West Main Street" didn't have the word "West" spelled out completely, we wouldn't get our mail! Crazy! All my BLOCK issues have arrived safely. We're having mail forwarded right now, so I called MSQC when I had a notification about the #4 issue and they assured me that I'd be home before it arrived. WHEW!
