Maps of US Area Codes

Using Area Code Mapping to Visualize Your Data

You can easily create a map of US area codes with Mapline. A note on area codes: Area codes were first introduced in the US with the Bell System in 1947. An area code is a numbering plan developed based on geographic areas. Each plan area is assigned a numeric routing code (area code) which is placed before the telephone numbers assigned within that area. In the US, a fixed length of 3 digit numbers represent an area code.

Since New York has the highest call volume, it was assigned the 212 area code – the easiest and quickest code to dial on a rotary phone. Next is Los Angeles (213), Chicago (312), Detroit (313), Philadelphia (215), and Dallas (214).

Because US area codes are based on call volume, area code mapping can give you a lot of information about your data in a particular region. Area codes often cover a larger geographic space than do zip codes, so you can see populations from a bigger-picture standpoint. They can cover whole cities, sections of cities or entire states, and increasingly people are identifying more and more with their area codes, using them as an indicator of local pride, especially in urban areas.

Get insights into your data with telephone area code maps and see how your sales, distribution or other factors are performing in specific regions.
