My family uses unit numbers, but not very often. Names work just as good.
In my family; my wife and I, and our oldest son are all hams. Our 2 younger sons are not hams. (yet)
What's funny is that our youngest son takes this GMRS identification business more seriously than any of the rest of us. I will call him on GMRS as: "Hey Mike, it's Dad, copy?" He will respond with: "This is WQYM-Five Four One, unit 5 to unit 1, go ahead Dad."
