Off on a tangent somewhat, but is there any sort of numbering system
applied to these modern ID numbers or is it more or less random
allocation?

I'm familiar with the old-style IDs such as "914-1" for White Plains
etc., but I've never been able to figure out how the current system is
supposed to work.

For example, dialing into the NANP from the U.K. using an unallocated
prefix within a valid area code often results in a "Your call cannot
be completed as dialed" recording with an ID of "two" followed by two
letters, e.g. 2BM. Are these class 2 tandem offices? Does the
network even still use the same class designations as in the past?
