Telephone Area 300

In the United States, telephone numbers are divided into a country code (+1), an area code (or prefix), which is three digits long, and a subscriber number (seven digits).

These are just a few examples, and there are over 300 area codes in the United States. Each code can cover both large cities and less populated areas depending on population density and telephone network distribution.

The table below lists the states and cities that use these prefixes of phone numbers. If you have not found the required prefix in the table, use the search by the exact number.
