The 973 area code covers north-central New Jersey — Newark, Morristown, Paterson, Passaic, Wayne, Parsippany, and surrounding communities. Callifi provides 973 business phone numbers with hosted VoIP, on-site installation, and local support.
The 203 area code covers southwestern Connecticut, including Fairfield County (Stamford, Norwalk, Bridgeport, Danbury, Greenwich, Westport) and New Haven County (New Haven, Milford, Meriden, Waterbury). Originally Connecticut's only area code, 203 was split in 1995 when the 860 code was created for the rest of the state. The 203 region is one of the most commercially important corridors in the Northeast — home to Fortune 500 headquarters, hedge funds, financial services firms, and professional services companies. Many 203-area businesses work closely with clients in Manhattan and need seamless connectivity between Connecticut and New York.
Call Callifi at (203) 599-4048 or our main line at (212) 423-1234. We provide 203 business numbers with a full hosted VoIP system. Porting existing 203 numbers takes 3-5 business days with zero downtime.
