Re^2: Shorter ID Codes

Of course if you use A..Z then you may introduce confusion between 0 => O and I => 1.

Update: Good point below, although you could mitigate that by reading it back using a phonetic alphabet (papa delta bravo tango), but again that'd take longer.

I'm going to echo this and add that purely numbered IDs are much easier to hear. There is tremendous aural confusion around B & D & P & T etc, even among speakers with the same accent. You might find that while 4242 4242 4242 4242 takes longer to read it's a false economy to switch it out with something like PDBT.	[reply]
