Spoken Numeric Labels

This is a question about spoken non-arithmetic numbers – numbers found in labels and identifications such as telephone numbers, badge numbers, account numbers, years, telephone numbers, license plate numbers, and street addresses, for example.  Numbers you don't add, subtract, or otherwise manipulate.

Is there a uniform, standard way of speaking such numbers?

In American English, I tend to be relatively casual about this.  For example, when asked my phone number, I usually reply with each digit of the area code and exchange, but the remainder I express as something like "twelve forty seven".  But if the last four digits were 8006, I'd never say "eighty six" for that would be ambiguous and leave my listener wondering what the remaining part of the number was.

It occurs to me that this could be ambiguous in another way in French.  If my address were 427 Main Street, in English I'd not hesitate to say "four twenty seven Main Street", but in French, "quatre vingt sept" has a completely different meaning.  As another example, 6012:  "sixty twelve" would be no problem, but "soixante douze" would send my auditeur to the wrong address.

Even if unambiguous, is there a standard?  When I first started learning French, I learned the year as something like dix-neuf cents soixante-six.  In English, we'd (usually) leave off the "hundred" and just say nineteen sixty six.  Formally, we might hear "in the year one thousand nine hundred and sixty six".  Since then I learned that "mille neuf cents …" is acceptable, too.  (Is one preferred over the other?)

I don't recall ever hearing a ZIP code spoken in English other than digit by digit.  "Oh five oh three eight."  Certainly never "five thousand thirty eight."

Okay, so that's my question.  How do les français and other francophones speak such numbers?  Does the Academie dictate this?
