In Cause No. PUD 201800086, Neustar, Inc., the North American Numbering Plan Administrator ("NANPA"), in its role as the neutral third party NPA Relief Planner for Oklahoma under the North American Numbering Plan and on behalf of the Oklahoma Telecommunications Industry, petitioned the Oklahoma Corporation Commission for approval of the Industry's consensus decision to recommend to the Commission an all-services distributed overlay as the preferred form of relief for the 405 Numbering Plan Area ("NPA").

On January 8, 2020, the OCC ordered that an all-services distributed overlay shall be utilized to provide relief for the impending exhaust of the 405 NPA. The all-services distributed overlay area code is 572.

• October 24, 2020 – Permissive 10-digit dialing began
• April 24, 2021 – Mandatory 10-digit dialing began
• May 24, 2021 – 572 area code added for new phone numbers

No, this change will not change how local calls are billed (i.e., local calls will remain local calls, regardless of whether the number dialed is a 405 or 572 area code).
