I don't know this is the answer here - but I know of one manufacturer - with the least creative company name in the semiconductor industry, possibly the entire world - whose serial numbers for at least some product lines, despite being stored as bytes, consist entirely of values between 0 and 99.
That said, if I ever saw a serial number printed by anything, and it started with a numeral zero followed by a lowercase b, I would have to excuse myself from any conversation I was having at the moment, becuase I wouldn't be able to hear the other person speak over the alarms blaring in my head....
