Area Code 918 was created in 1953 for serving the Northeastern areas of the Oklahoma State of United States. The particular code was created for providing numbering relief to area code 405. The 405 area code was getting exhausted because of the ever increasing demands foe telephone lines. It was necessary to split off the exhausted area for providing the customers with telephone services resourcefully and efficiently.
The newly created area code-918 was reserved for Northeastern particularly the Tulsa region of the Oklahoma State.
