How to say class numbers?

[D6975]

How would you say 150271? One-fifty-two-seven-one? So it sounds like 15271?

I'd say 150271 as one five oh two seven one.

Oddly enough for the class 43 I say one-two-five

The 777 is the exception! Seven-seventy seven is too much of a mouthful of sevens, as is seven-seven-seven. People in the business almost universally refer to it as the triple seven. They also refer to the other Boeings as just seven-three, seven-five, seven-eight etc.

Or they refer to the Boeings as the first two numbers of type plus the first of the variant. So a 744 is a 747-400.

And a 91 would be two two five?

I tend to go with the following:

73 - Seventy-three
158 - One-five-eight
175 - One-seven-five
350 - Three-fifty
507 - Five-oh-seven

Although when it comes to individual units (for example 350118) I'd say three-five-oh-one-one-eight. Not very consistent!

Who determined what terminology is "correct"|?

It's very appropriate that such an authoritative post should be made by somebody called "Controller"!

Nowadays everything has to be said in a very unambiguous way.

So just as in aviation the phonetic alphabet is used and numbers are stated zero to nine (niner is used in aviation). It is done so that over radio or SPT it is 100% clear what is being said at all times.

Yes, I appreciate the importance of 100% clarity in an operating environment, but who determined that this approach should be used - DfT, Railtrack, Network Rail, RSSB....?

Outside the operating environment, when I was standing with a group of enthusiasts watching an excursion train a few weeks back, and someone commented that there was a Class Sixty at one end and a Sixty Seven at the other, I think anyone who'd declared "Six Zero and Six Seven, please, my good fellow" would have risked being booed off the pitch.
