Telecommunications
Southeastern Pennsylvania was served only by the 215 area code beginning in 1947 when the North American Numbering Plan went into effect. The area covered by the code was severely truncated when area code 610 was split from 215. Today only the city and its northern suburbs are covered by 215. Overlay code 267 was added to the 215 service area in 1997. A plan to introduce area code 445 as an additional overlay in 2001 was delayed and later rescinded .
Philadelphia is now also served by Wireless Philadelphia, a citywide initiative to provide Wi-Fi service. the Proof of Concept area was approved ony May 23, 2007 and service is now avaialable in many areas of the city.
