The teams I've been on:

1075: Ten Seventy-Five.
4343: Forty-three forty-three.

I agree with most of the previous posters that the general formula seems to be to read them as two two-digit numbers (ie. Eleven Fourteen), (or a 1 digit followed by two digit, ie. Two Seventeen), except when the tens digit is a zero, and then its "Twenty Seven Oh Two", or "Seven Oh Three". There are also a few outside cases like 4001: "Four Thousand and One", or 2200: "Twenty-Two Hundred".

What I found really interesting though, is the french-language teams.

Most of the francophone teams refer to themselves (and others) in the same split format, 1075 becomes "dix soixante-quinze" and 1547 becomes "quinze quarante-sept", but the announcer at the montreal regional announced teams (anglophone and francophone), in their language, as individual digits "team one zero seven five", "equipe trois trois six zero".
