A new area code was approved this year on January 8 by the Oklahoma Corporation Commission to serve the central portion of the state currently using area code 405. Some of the towns and cities in the 405 Numbering Plan Area include: Arcadia, Blanchard, Carney, Dover, Oklahoma City, Tecumseh or Yukon. The new code will enter service next year in the month of May. As a result, 10 digit dialing will be introduced for all local calls in the area and 11 digit dialing for toll calls.
