American 240v service is two 120v lines out of phase with each other. Thus yes, far as most private one to three family homes are concerned 240v electrical service is what enters breaker panel/box.
What happens afterwards is often another matter. Some homes have 120v/240 outlets about the place, others do not. Usually (but not always) in areas where natural gas lines are absent or for other reasons electricity is used say for heating/HVAC, cooking, clothes dryers, hot water, etc... you'll find 120v/240v outlets.
Even where there are gas lines say for a range or dryer homes will have electrical 120v/240v in kitchen, laundry area or wherever to give an option. If it isn't there such outlets can easily be installed.
Multi-family and other buildings have 240v coming in from street to main panel, but not every individual box or apartment is wired for such service.
Despite people always going on about how "everyone" has 120v/240 service in USA that wasn't or isn't true. Miele and other European appliance makers lost many a sale because home or apartment was not wired for 120v/240v service. Worse tenant or owner of unit wasn't allowed (by landlord or co-op board) to install said service. That and or they weren't interested in incurring cost which could be substantial.
Depending upon how electrical box was wired for individual apartment in question and perhaps from street to building upgrading service could be a major undertaking.
