To make a call to a domestic phone number in the United States, you can follow this way in English:
Dial the country code of the United States (it’s "1"), then the area code of the city you want to reach, followed by the specific phone number you want to call. For example, if you want to call a number in New York City, the area code is "212," and the phone number is "1234567890," you should dial "1-212-1234567890."
Note that some phone companies may charge for international calls, so it’s important to check with your phone company before making the call to avoid any unexpected charges.
