Create a Telephone Area Code Map

Using US Area Code Maps to Visualize Your Data

US area code mapping is simple with Mapline. 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 three-digit numbers represents 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 zip codes, so you can see populations from a bigger-picture standpoint. They can cover whole cities, sections of cities or entire states. Increasingly, people are identifying more with their area codes and using them as an indicator of local pride, especially in urban areas.

You can easily create a map of US area codes with Mapline. Get insights into your data with territory mapping and analysis. Use telephone area code maps and see how your sales, distribution or other factors are performing in specific territories or regions.
