Details About How many area codes are in America:
In the US, there are 380,600,000 phone numbers, which is strange considering that there are only 331 million people and 18% of them are under the age of 14. However, this figure is attributed to landlines, work, and burners. Even though a phone can only have ten digits, an area code can have seven distinct numbers, which means that a code can have 7,920,000 numbers in total.
