Find any 816- phone number in Missouri

The 816 area code is a telephone area code in the state of Missouri. It is one of Missouri's three original area codes, which were established in 1947 when the North American Numbering Plan (NANP) was created. This area code originally served the entire state, but has since been split to form several other area codes and is now largely used in the Kansas City metropolitan area.

The 816 area code is a part of the North American Numbering Plan, which is a system of organizing and allocating phone numbers to telecommunications providers in the United States, Canada, and some Caribbean nations. This system was established to better organize phone numbers and make them easier to remember. Area codes are determined by the NANP in an effort to divide up the country into geographical segments. Each area code is then assigned to a specific geographic area, such as a state, province, or city. Each number within the area code is unique and assigned to a specific customer of a telecommunications provider.
