History and Evolution of the Code
Area code 816 has a long history, dating back to the establishment of the North American Numbering Plan. For a very long time, it was the sole area code for the entire western part of Missouri. This changed in 1997 when the proliferation of cell phones and fax machines created a need for more numbers. As a result, the 975 area code was introduced as an overlay for the 816 region. Later, in 2022, the 975 area code was replaced by the new 913 area code for Kansas Kansas City, solidifying the current distinction between the Missouri and Kansas sides of the metro area.
Why Multiple Overlays Matter
The introduction of overlays like 975 and 913 was not just about running out of numbers; it was a strategic decision to manage telecommunications growth. An overlay allows multiple area codes to serve the same geographic region. This means that new phone numbers can be assigned with the 975 or 913 codes even as the 816 area code continues to support existing numbers. This system ensures the stability of the telephone network, preventing the need for widespread number changes and the confusion that would ensue.
For anyone looking for the Kansas City area code, it is vital to specify whether they are looking for the Missouri side (816) or the Kansas side (913). This distinction is critical for routing calls correctly and avoiding misdials. Businesses operating in the region must be particularly aware of this when listing contact information, ensuring they use the correct code for their target audience. The 816 area code remains a proud symbol of identity for the Missouri side of this dynamic metropolitan area.
