Look at the electrical panel. It will have a main breaker at the very top and will be labelled 100 or 200 depending on amps.

Wire size and meter can size. a 100 amp meter can is considerably smaller than a 200 amp. You can go to a hardware store and measure them because newer ones are all about the same dimensions. Wire size is the only definite way to tell the size of the service though. 2 ought wire is the minimum size of a 200 amp service on a residential (house) service, but 3 ought is the minimum for a commercial service. Anything less than 2 ought on a house is not a 200 amp service. All above answers are not necessarily correct. a service can be 200 amps and have a 100 or 150 amp main.
