Southeastern was a United States Postal Service regional Processing and Distribution Center (P&DC) in Tredyffrin Township, Chester County, Pennsylvania, United States, near Devon. It was primarily known for its post mark on mail originating in many ZIP codes in the region. The retail post office remains open at the location of the former P&DC. Many bills for Verizon Communications and Comcast as well as statements from The Vanguard Group are sent from this post office. Videos for Netflix were also sent from this post office for customers in the Philadelphia region. This post office served as the regional mail center for the 193xx group of zip codes and post offices, and much of the mail from this area to the rest of the country bore a Southeastern, PA 193xx postmark instead of the actual zip code of origin. Prior to closing, Southeastern processing was being studied for consolidation with other facilities due to the excess capacity in the postal network. On September 8, 2010, notice was given to the postal union of possible consolidation with the Lehigh Valley P&DC. On September 15, 2011, the USPS announced that they were studying a consolidation into the Philadelphia P&DC. A public meeting was held on January 3, 2012. According to a published summary of the study, "retail and other services currently available at the Southeastern facility will not change at this time."The Southeastern P&DC was consolidated into the Philadelphia P&DC in 2012–2013.

Philicon Valley is a neologism for Philadelphia's version of Silicon Valley. Forbes coined the term on November 17, 1999 to refer specifically to the suburbs of Valley Forge and Wayne, Pennsylvania, which was also referred to as "Silicon Valley Forge" and "E-Valley Forge." In the Delaware Valley, many "... new-economy companies have located themselves in the suburbs along Route 202..." due to the high tax base in the city of Philadelphia. From a marketing perspective, the term has been used by Internet companies to lure potential employees in the tech sector, that markets the firm as part of a large community of like companies in a suburb of Philadelphia. "Pennsylvania Dutch Country is only about a 90 minute drive away..." noting that the area is home to "... large high-tech companies..." The lure in the region has many Penn graduates, as well as other graduates do not consider Philadelphia to be the "hot spot" and some have chosen this region as an alternative. A briefing on the region, says the area contributes to Pennsylvania being ranked eighth in hi tech employing more than 170,000 according to the Ben Franklin Technology Partners of Southeastern Pennsylvania, WHYY-TV, and the Council for Urban Economic Development.
