But, remember, the first 3 positions indicate a zone, so that affects
your calculation of how many are available.
Back in the '80s, I worked for a banking software firm and we were
notified by the feds that all software relating to SSNs needed to be 10
digits because there would be an expansion 'down the road'. We complied.
Since we were using packed numbers, we changed everything to S9(11), but
we only displayed 9 positions on the BMS screens since 11 positions
would have confused everyone.
Ok, it's been 30+ years and we have not seen it actually expand, but
they did tell is...
(Just like we knew in the 80's that Y2K would be upon us 'down the road'.)

9 characters with 10 possible values = 10 to the 9th = 999,999,999 aka = 1
billion.
Allow one position to be alphanumeric adds what? Does position matter?
Thought 10 to the 36th plus 10 to the 8th??
But if allow all alphanumeric = 36 to the 9th = ?
