    Pennsylvania area code

    Pennsylvania is one of the thirteen states that founded the United States in 1787, following the declaration of Independence. There are nearly 13 million persons living in the Keystone State and most have a phone number. Looking at Pennsylvania area codes is one way to tell an unknown caller’s city or town on the Pennsylvania phone numbers database.

    Phone companies in Pennsylvania used to connect callers using a phone number that comprised two letters and five numbers (2L-5N). The two letters (2L) help the caller know the switchboard to dial (which would be a mobile carrier today), while the last five numbers, 5N, were the call recipient’s unique identifier.

    Today, phone companies use a 10-digit all-number system of:

    • a three-digit area code
    • a three-digit prefix code, and 
    • a four-digit line number.

    This system helped phone companies meet demands for phone numbers in Pennsylvania.

    Take your typical ten-digit Philadelphia phone number, 267-PHH-XXXX, and think of it as a physical house address.

    267 is the area code, which represents a geographic area within Pennsylvania. In a house address, this would be your county or city of residence – in this case, Philadelphia.

    The next three digits, PHH, make up the prefix code. In a house address, this would be your town or street name within Philadelphia.

    The last four digits, XXXX, is the line number that is unique to every phone number owner. In a house address, this would be your house number, flat number, or room number.

    Pennsylvania started with four area codes in 1947 based on the North American Numbering Plan. Soon enough, four area codes proved insufficient to cover everyone who needed a phone number, so the state created new phone numbers using overlay and geographic split. 

    Besides connecting you with the person you wish to call, area codes also let you identify an unknown caller’s general location. But you will need a reverse phone search to get more specific information about the caller’s address and public records from the Pennsylvania phone numbers database.

    Several persons can have the same area code if they live in the same area. Close neighbors can even have the same prefix code. However, line numbers are unique. No two persons can have the same line number, but one person or business can have several line numbers.
