Couldn't you also just make your phone's title your name?
You misunderstood a bit. My dog tag is so old that it doesn't have a social security number on it, my original service number is all that is listed on it.
I have plenty of I.D. for someone to ID me by. My DNA is on record just in case I get wiped out totally and they just find a few cells of me.
Mine was only 7 characters. x xx xx xx
I'd put it down but it is one of those unique numbers that I use for my passwords, nobody knows it but me!
Current dog tags are no longer notched.

When I told people what the notch in dog tags were really for, the fable must have sounded better to them. The notch, for you younger troops, was an alignment aid when the tags were typed in the old machines.
