Commission determines 715 and 920 area codes will get overlays

by preferred on November 6, 2008

Docket 5-TN-100. The most recent forecast indicates that the 715 area code will run out of assignable central office codes (or NXXs) in the first quarter of 2011, while the 920 area code is expected to exhaust in fourth quarter of 2011.
The two basic methods of area code relief are an overlay or a geographic split (split).
An overlay occurs when more than one area code serves the same geographic area.
