Overlays and Numbering Considerations
Currently, there is no overlay code for the 845 region, meaning the area code is unique to this geographic area. However, number portability allows subscribers to retain their 845 numbers when switching between fixed-line operators, which may result in calls to VoIP or mobile networks. Callers should be aware that despite the geographic nature of the code, the called party may be served by a non-geographic platform.
