It shouldn't be difficult, BZ6 is code 0072; see para 3:

Thanks Roland, that's very useful. But is just possible that some
ticket clerks don't know this stuff?

If their job, all day long, is selling tickets, they really ought to
know at least a substantial subset of those codes. Or have a
company-provided crib sheet.

And when the alphanumeric for BZ6 is "Boundary Zone 6", there's really
no excuse...
