[nos-bbs] BID/MID Limitations

Is there a definitive source of information as to how the various bbs
systems use BID and MID?  Here's the scenario.  My JNOS system has been
running since the late 90s and my numbers are approaching 1 million!
What I have found out is that when my number is something like 976405,
it gets circulated around as 76405 and a mismatch occurs when checking
the number to see if a system already has it or it gets duped.  Not good.

We would have more wiggle room if letters were used along with the numbers.

5 Character Limitation(?):
Numbers only = 10 * 10 * 10 * 10 * 10 = 100,000
Both numbers/letters = 36 * 36 * 36 * 36 * 36 = 60,466,176

6 Character Expansion:
Numbers only = 10 * 10 * 10 * 10 * 10 *10 = 1,000,000
Both numbers/letters = 36 * 36 * 36 * 36 * 36 = 2,176,782,336


Of course, this will only work if the bbs systems can make use of this 
scheme.
Let's put our collective and aging brains together to solve this problem.
