305 round hundreds numbers

A round-hundred number ends in two digits and 00: 305-XXX-2100. Said as "twenty-one hundred", it sounds like a main switchboard, and the numbers next to it can be used for direct lines.

It is a natural main line for a professional office, from a Brickell law firm to a medical group in Kendall. The zeros are just as easy to hear in Spanish, which suits a bilingual front desk.
