Comcast Headquarters Address, Corporate Office Location, and Contact Details

About

Comcast Corporation (NASDAQ: CMCSA) is the largest cable and broadband provider in the United States and one of the world’s largest media and technology conglomerates, headquartered at Comcast Center, 1701 John F. Kennedy Boulevard, Philadelphia, Pennsylvania 19103 — the 58-story glass skyscraper that is the tallest building in Philadelphia and was the largest private commercial development in Pennsylvania’s history at the time of its construction. Comcast was founded in 1963 by Ralph J. Roberts, Daniel Aaron, and Julian Brodsky in Tupelo, Mississippi as a single cable system operator with 1,200 subscribers, and has since grown through relentless acquisition and organic expansion into a $123.7 billion Fortune 50 conglomerate. The company operates through three major divisions: Connectivity & Platforms (Xfinity cable TV, broadband, wireless, and smart home — the largest cable and broadband business in the US serving 50.8 million total customer relationships); NBCUniversal (NBC broadcast network, MSNBC, CNBC, E!, Syfy, USA Network, Telemundo, Universal Pictures, DreamWorks Animation, Peacock streaming, and Universal theme parks in Orlando, Hollywood, Osaka, Beijing, and Epic Universe opening in 2025); and Sky (Europe’s largest pay-TV and broadband platform, acquired for $39 billion in 2018, serving 23+ million European customers across the UK, Germany, Austria, Italy, and Switzerland). For FY2025 (ending December 31, 2025), Comcast reported total revenue of $123.71 billion (flat YoY), full-year net income of $19.998 billion (+23.5% YoY), adjusted EBITDA of $37.384 billion, adjusted EPS of $0.84 for Q4, and returned $11.7 billion to shareholders — including $6.7 billion in share buybacks reducing share count by 5%. Comcast’s broadband business continues to face subscriber pressure from 5G fixed wireless competitors (T-Mobile and Verizon), losing 181,000 broadband customers in Q4 2025, though Xfinity Mobile continues to grow, adding 364,000 wireless lines in Q4 to reach 9.31 million total.

About the Comcast Center: The Comcast Center at 1701 JFK Boulevard is a 58-story, 975-foot glass tower designed by world-renowned architect Robert A.M. Stern — the tallest building in Philadelphia and at the time of its completion in 2008, the largest private commercial development ever built in Pennsylvania, constructed under a 15½-year lease signed in 2005 with Liberty Property Trust. The tower anchors Comcast’s presence in Center City Philadelphia and houses thousands of Comcast corporate employees across executive leadership, finance, technology, marketing, HR, and legal functions. Adjacent to the Comcast Center, Comcast completed the Comcast Technology Center at 1800 Arch Street in 2018 — a second skyscraper serving as Comcast’s technology and innovation hub. Together, the two towers make Comcast the defining corporate presence in Center City Philadelphia and among the city’s largest private-sector employers.

How to Escalate a Complaint

1. Call Xfinity at 1-800-934-6489 first — For the vast majority of residential billing, service, and equipment complaints, Xfinity’s 24/7 customer service line is the starting point. Request a supervisor if your initial representative cannot resolve the issue.
2. Request a retention specialist or escalation supervisor — When calling 1-800-934-6489, explicitly ask to speak with a “retention specialist” or “executive customer relations” team member — these agents have greater authority to issue credits, waive fees, and modify contract terms.
3. File with the FCC — File a formal complaint at fcc.gov/consumers/guides/filing-informal-complaint. The FCC has regulatory authority over Comcast’s cable and broadband services. FCC complaints typically generate a formal response from Comcast’s regulatory relations team within 30 days.
4. File with your state Public Utility Commission (PUC) — State PUCs regulate cable and telecom services in most states. Comcast complaints filed with the state PUC typically receive a faster response than FCC complaints. In Pennsylvania: puc.pa.gov.
5. File with the CFPB — For Xfinity Mobile billing disputes and financial product-related complaints, file at consumerfinance.gov/complaint.
6. Mail to the Philadelphia HQ — Write to Comcast Corporation, Office of Executive Customer Relations, 1701 JFK Boulevard, Philadelphia, PA 19103. Send certified mail. Include your account number, prior contact history, and the specific resolution requested.
7. File with the BBB — Comcast is listed with the BBB (not BBB Accredited). File at bbb.org — Comcast has a long-documented complaint history on the BBB platform.
8. File with the FTC — For deceptive billing practices, promotional pricing bait-and-switch, or data privacy violations, file at reportfraud.ftc.gov
