The present USA voltage standard range is 120/240VAC 60Hz at +-5%, and has been for many years. There are exceptions to this in large buildings, where polyphase systems are sometimes used, but standard single phase residential and light commercial is all 120/240 service. We haven't had 110/220 for well over 60 years.
In the US, 120V is the standard single phase voltage with one 120V power wire and one neutral wire. In some countries, 230V is the standard single phase voltage with one 230V power wire and one neutral wire.
