In Europe I know of the suffix being used to indicate apartment number, or floor number - e.g. 379-3 meaning Street Address 379, Floor/Flat 3. Sometimes other characters are used for the floor/flat such as A/B/C or I/II/III - in these cases it is unambiguous because it is non-numeric.

If you mean the US example, some friends were living in Long Island
City, Queens, NY, and their apartment address was something like
1100-157 50th Ave. The other examples are possibly typically European.
Here in the Netherlands there are all kinds of notations in use for
sub-units. The national addressing standard has a field for an
alphanumeric "house number suffix" for this that people in IT know
about, but the average Johan might not know what a
"huisnummertoevoeging" is. Normally the full number, including the
suffix, is written together with some kind of separator. 

There are also areas where the whole neighbourhood has a single street
name, and everybody has a very long house number; the initial digits of
the house number indicate the specific road within the neighbourhood.
Sometimes these house numbers are written as 123-45 to aid navigation.

As I mentioned above I know that hyphenated addresses can be used for
subdivisions (apartments etc). Are there any other scenarios for
hyphenated addresses?
