Southwest Airlines doesn't have a traditional "office" in NYC, but they operate out of LaGuardia Airport (LGA), primarily using Terminal B, with ticket counters open before flights for specific New York-area support, you call their main numbers for Reservations, Baggage, or Groups, like the number found on MapMyRun for assistance (+1-866-829-1086), but always check the official Southwest site for current airport info.
