A typical US phone number consists of a total of 10 digits, which include the area code, exchange code, and line number. If you are calling the US from outside, use the following format: your country’s exit code + 1 + area code + local phone number. Local, toll-free, mobile, vanity, and emergency numbers are the types of US phone numbers.
Step 2: After dialing the exit code, dial 1, which is the country code for the United States. This code indicates that you are placing a call to a US-based phone number. Step 3: Next, dial the three-digit area code specific to the region you are trying to reach within the United States.
