Hi Ted,
Some large multiple dwellings or older densely populated areas
have 208/120. The service is a three phase Y...using three 120 volt
transformers.
You get 120 from any legs to neutral/ground, and 208 between any
two legs.
That's largely gone now, but you may have a 120/208 service (you
won't have the last wire needed for the three-phase most likely).
