The address gods must really frown on such things.
My reason for asking is sort of cheating, I guess. I just came across a 6666 address on a Shreveport street. A co-worker tells me the fourth 6 probably cancels out the evil powers of the other three.
I realize home owners probably don't get to pick the actual digits in their address, but I think I'd have to look on another street or beg the city to renumber my plot.
Either way, the multitude of 6s is just kind of creepy.
Why do I even care? I suppose because when I was little, my family's P.O. box was 777, and I thought that was so cool. But any address (especially a lucky one like that) would be better than any combo of the triple 6!
