PSC MODIFIES HEARING SCHEDULE IN 314, 636 AND 816 AREA CODE ISSUES
Jefferson City (March 22, 2000)---The Missouri Public Service Commission has modified,
based upon a request by various parties, the hearing schedule in a case examining 314, 636 and 816 area
code issues in Missouri.
Hearings, originally scheduled for June 19-22, 2000, are now scheduled to begin on July 31,
2000, in the Commission’s hearing room which is located on the fifth floor of the Truman State Office
Building in Jefferson City. These hearings will continue through August 3, 2000, if necessary.
Parties to this case requested additional time based upon anticipation of a Federal
Communications Commission (FCC) decision on a number of issues including number pooling. The
additional time was sought in order for parties to be able to address the anticipated order in their
evidentiary and legal presentations to the Commission.
CASE BACKGROUND: North American Numbering Plan Administrator NeuStar, Inc. (NANPA) filed a
petition with the Missouri Public Service Commission requesting the Commission approve “overlay”
plans to alleviate an apparent exhaustion of available NXX codes (telephone prefixes) in the 314 area
code in eastern Missouri (the St. Louis metropolitan area) and the 816 area code in western Missouri
(including the Kansas City and St. Joseph areas). The “overlay” plan proposed would also apply to the
636 area code in eastern Missouri.
NANPA suggests an “overlay” be introduced in the 816, 314 and 636 area codes as a means of
alleviating the exhaustion of available NXX codes. When NXX codes become unavailable, the new area
code is introduced. The introduction of a new area code will require ten digit dialing for local calling
(the area code plus the seven digit telephone number).
A significant reason for the apparent exhaust is the current industry-wide practice of issuing
numbers in blocks of 10,000. Other factors include an increasing demand for faxes, second lines,
cellular phones, pagers, as well as Personal Communication Service
